Suspended and dissolved biodegradable carbonaceous materials and nitrogenous materials present as contaminants in waste water, typically in raw domestic or municipal sewage, are substantially removed by a one-stage treatment. The waste water is contacted with a mixture of activated carbon and microorganisms, known herein as activated sludge, having molecular oxygen absorbed therein, which results in adsorption and biooxidation of the carbonaceous material, biooxidation of non-nitrate nitrogenous material to nitrate and depletion of the molecular oxygen whereupon biological reduction of the nitrate to nitrogen gases occurs. The nitrogen gases are vented and the resulting treated water is separated from the activated sludge. Regeneration of the activated sludge may be achieved by air stripping, after which the regenerated activated sludge material may be recycled. Further, the treated water may be subjected to clarification to complete the biological reactions and to remove residual suspended solids. The activated sludge from the clarification may be regenerated by air stripping followed by recycle of the regenerated material to the reactor.

This application is a continuation-in-part of application Ser. No. 436,480 filed Jan. 25, 1974 now abandoned.
The present invention relates to the treatment of waste water.
Waste waters, typically domestic and municipal sewage, contain a variety of contaminants, typically biodegradable suspended, colloidal and dissolved carbonaceous materials, various nitrogenous compounds, including organic nitrogen compounds, ammonia and nitrates, and phosphate materials.
It is relatively simple to remove carbonaceous and phosphate materials from waste water, but rather difficult to remove nitrogenous materials. It is known that it is possible to remove nitrogenous materials biologically or by physical-chemical processes.
One prior art procedure which has been suggested for the biological removal of nitrogenous materials is a three-stage biological system which includes ammonification and nitrification of the nitrogenous materials under aerobic conditions followed by denitrification under anaerobic conditions. The denitrification procedure involves the addition of energy in a chemical form, typically as methanol. This prior art procedure is described by Barth et al in JWPCF vol. 40, No. 12, p.2040 (1968). In this prior art proposal, the treatment process consists of three separate biological sludge systems. Each system has its own recycle and is distinct from the others. The waste water flows through these systems in series, with intermediate settling between the systems. In this way, the biological activities of carbon oxidation to remove carbonaceous materials, ammonification and nitrification and denitrification to remove nitrogenous materials are isolated from each other and occur in three separate stages.
This procedure is successful in the removal of the contaminants, but suffers from several drawbacks. The procedure is time-consuming, results in high net sludge production, has three separate stages of aeration and clarification, and involves considerable control and operating expenditures.
In accordance with the present invention, waste water containing biodegradable carbonaceous materials in solid, colloidal or dissolved form and nitrogenous materials in organic nitrogen, ammonia, nitrite and nitrate form as contaminants is subjected to a one-stage adsorption-biological oxidation process for the substantial removal of these contaminants from the waste water.
FIG. 1 is a schematic flow sheet illustrating one embodiment of the invention;
FIG. 2 is a schematic flow sheet illustrating a second embodiment of the invention;
FIG. 3 is a part-sectional view of a reactor for use in the embodiment of the invention illustrated in FIG. 2; and
FIG. 4 is a part-sectional view of a clarifier for use in the embodiment of the invention illustrated in FIG. 2.
Referring first to the embodiment of FIG. 1, sewage, or other contaminated waste water, which may be domestic, municipal or industrial sewage, after removal of gross solids by screening or in a primary clarifier is fed to the top of the reactor 10 by line 12. A recycled mixture of powdered activated carbon and microorganisms, known hereinafter as "activated sludge", in line 14, also is fed to the top of the reactor 10 along with the sewage in line 12. The recycled mixture in line 14 is formed as described in more detail below and contains quantities of absorbed oxygen.
The reactor 10, generally of cylindrical shape, includes a first chamber 16 in which the mixture of sewage and activated sludge flows downwardly towards a second chamber 18 located in a lower end closure portion 20 of the reactor 10. The end closure portion 20 generally is of conical shape.
An inverted funnel-shaped member 22 is positioned in the reactor 10 defining a third chamber 24 which is out of fluid flow communication with the first chamber 16, other than through the second chamber 18.
In the first chamber 16, the suspended, colloidal and dissolved organic materials contained in the sewage are adsorbed onto the activated carbon and/or absorbed into the microbial cells, any residual organic materials being removed at a later stage. The adsorbed organic material is biologically oxidized by the microorganisms, while organic nitrogen is converted to ammoniacal nitrogen and ammoniacal nitrogen is biologically oxidized by the microorganisms to nitrites and nitrates.
The biological oxidations occuring in the first chamber 16 deplete the absorbed oxygen to a level at which the heterotropic microorganisms in the activated sludge cause anaerobic conversion of nitrite and nitrate to nitrogenous gases, mainly nitrogen and nitrogen dioxide, as the microorganisms utilize the oxygen values of the nitrite and nitrate. The biological reactions occur simultaneously in the first chamber 16.
The resulting mixture of activated sludge, processed waste water and gaseous substances passes from the first chamber 16 to the second chamber 18.
Part of the sludge separates from processed waste water in the second chamber 18. The processed waste water, some sludge and the gaseous substances, consisting mainly of nitrogen, nitrogen dioxide and carbon dioxide, pass upwardly from the second chamber 18 to the third chamber 24 within the inverted funnel 22.
The liquid effluent from the reactor 10 is removed by line 26 leading from the throat section of the inverted funnel 22. The gases separated in the second chamber 18 are vented to atmosphere through the throat of the inverted funnel 22. The effluent in line 26 has a substantially decreased content of organic substances and nitrogenous materials as compared with the sewage fed by line 12. The reactor 10, therefore, in a single vessel has removed from the processed waste water substantial quantities of the carbonaceous materials and has converted substantial quantities of the nitrogenous material to nitrogenous gases.
The reactor 10, therefore, performs a number of functions on the contaminants of the waste water. Among these functions are those of subdivision of suspended solids by hydrolysis, separation of dissolved organic matter by adsorption on activated carbon and microbial cells, biological oxidation of adsorbed organic matter, biological conversion of organic nitrogen to ammoniacal nitrogen, conversion of ammoniacal nitrogen to nitrites and nitrates and conversion of nitrites and nitrates to nitrogenous gases.
The effluent in line 26 is passed to a clarifier 28, possessing a first chamber 30, a second chamber 32 and a third chamber 34, the latter chamber being maintained out of fluid flow communication with the first chamber 30 other than through the second chamber 32 by an inverted funnel 36.
The effluent in line 26 fed to the first chamber 30 of the clarifier 28 is contacted by recycled activated sludge fed thereto by line 38. This recycled mixture is formed as described in more detail below.
The coagulation and sedimentation of suspended solids from the reactor effluent is improved by addition of the reactivated sludge into the first chamber 30 of the clarifier 28 by line 38. A substantial proportion of the remaining quantities of carbonaceous materials and nitrogenous materials present in the effluent are biologically consumed, thereby further purifying the treated waste water. Since the concentrations of carbonaceous and nitrogenous materials in the reactor effluent in line 26 are very low, the dissolved oxygen in the return sludge in line 38 is not depleted and aerobic conditions exist throughout the clarifier 28, in contrast to the presence of both aerobic and anaerobic conditions in the reactor 10.
In the second chamber 32 of the clarifier 28, the sludge is separated substantially from the liquid phase which exists from the third chamber 34 of the clarifier 28 by line 40 from the throat of the inverted funnel 36. The effluent is substantially free from suspended solids, carbonaceous materials and nitrogenous materials.
The clarifier 28, therefore, performs a number of functions on the contaminants of the waste water remaining in the effluent from the reactor 10 in line 26. These functions include completion of the biological reactions on the carbonaceous and nitrogenous materials, and biological flocculation, sludge coagulation and sedimentation of suspended solids.
The water in line 40, however, may be subjected to further treatment, such as deep bed multimedia filtration with sand, anthracite and activated carbon to decrease further the suspended solids content and/or chemical treatment to decrease its phosphate content. The effluent in line 40 may be treated to provide water of potable quality by various procedures, including coagulation and filtration followed by disinfection; and/or reverse osmosis followed by disinfection; or evaporation followed by disinfection; or ion-exchange followed by disinfection.
The sludge which is separated in the second chamber 18 of the reactor 10 is removed therefrom by line 42 and is passed to an aeration tower 44. The sludge which is separated in the second chamber 32 of the clarifier 28 is passed by line 46 to the aeration tower 44, forming with the sludge in line 42 a composite sludge feed in line 48.
The aeration tower 44 may be of any convenient construction to allow intimate contact between gas and sludge, typically a multistage countercurrent contact column or a cross-flow reactor.
Air, or other gas rich in or consisting of molecular oxygen, is fed by line 50 to the aeration tower 44 wherein it contacts the sludge fed by line 48, causing stripping of volatiles from the sludge, saturation of the sludge with oxygen, reactivation of the carbon by oxidation of the carbonaceous and nitrogenous materials absorbed thereon, and oxidation of a portion of the microbial cells, thereby maintaining a balance of microorganisms in the system. The spent gases are vented from the aeration tower 44 through line 52.
The reactivated sludge is withdrawn from the aeration tower 44 by line 54 and is divided into two streams, one passing by line 14 to the reactor 10 and the other passing by line 38 to the clarifier 28.
In a modification of the embodiment of FIG. 1, feed of activated sludge by line 38 may be omitted. In this modification, some air may be added to the effluent in line 26 for the completion of the biological reactions in the clarifier 28. Alternatively, the addition of air to the effluent in line 26 may be omitted.
In a further modification of this embodiment of the invention, the sewage is fed to line 48 rather than directly to the reactor 10 by line 12.
Turning now the embodiment of FIGS. 2 to 4, a waste water treatment system includes a reactor 110 shown schematically in FIG. 2 and in more detail in FIG. 3 and a clarifier 112 shown schematically in FIG. 2 and in more detail in FIG. 4. Screened or primary clarified sewage is fed by line 114 to the reactor 110. Such sewage typically contains suspended solids, dissolved organic materials, organic nitrogen, nitrate, nitrite and ammonia values. The reactor 110 consists of an upright cylindrical outer container 116 and a cylindrical inner sleeve 118 located coaxially with the container 116 and spaced upwardly from the base 120 thereof to define a first chamber 121 between the outer container 116 and the inner sleeve 118. The inner sleeve 118 extends upwardly to a point located above the intended liquid level in the reactor 110.
A hollow riser-aerator tube 124 is positioned in the reactor 110 extending from the base 120 and upwardly through the second chamber 122 and beyond the upper extremity of the sleeve 118 and terminating exteriorally of the reactor 110.
The tube 124 is flared outwardly at the lower end thereof and is spaced upwardly from the base 120 to allow the passage of fluid into the tube 124. A gaseous material feed tube 126 extends downwardly from the upper extremity of the tube 124 to a position immediately vertically-upwardly displaced from the lower end of the tube 124 to allow the discharge of air, oxygen or a gas rich in molecular oxygen in the tube 124 adjacent its lower end.
The riser tube 124 adjacent its upper extremity but within the reactor 110 communicates with a cross-arm member 128 extending radially of the container 116 which in turn communicates with a tubular discharge member 130 at each radial extremity thereof. The tubular discharge members 130 include a downwardly-extending portion and a horizontally-extending portion positioned above and adjacent the intended liquid level in the container 116 and extending adjacent the inner wall of the container 116 to discharge fluid therefrom substantially tangentially.
While one such riser tube 124 with associated cross arm and discharge members 128 and 130 are illustrated in FIG. 3, any other desired number may be employed, depending on the requirements of the system.
A liquid effluent tube 132 is provided in communication with the second chamber 122 but out of communication with the first chamber 121 for removal of treated liquid from the reactor 110 through the second chamber 122.
A gaseous discharge vent 134 is provided at the upper end of the reactor 110 above the intended liquid level in the reactor 110 for discharge of gases formed in the reactions in the reactor 110.
An inlet opening 160 also is provided in the reactor 110 above the intended liquid level in the container 116 for feed of recycled activated sludge from the clarifier 112, as described in more detail below.
Sewage fed to the reactor 110 by line 114 mixes with mixed liquor suspended solids-activated sludge, discharged from the discharge members 130 and activated sludge recycled from the clarifier 112 and rotates in the first reaction chamber 121. By centrifugal action, the activated sludge particles together with suspended solids tend to partially separate and accumulate along the inner wall of the container 116 and also move downwardly under the influence of gravity and the downflow velocity of the liquid phase to accumulate in a third chamber 136 adjacent the base 120.
Adjacent the base 120 of the container 116, liquor is drawn into the riser tube 124 under the influence of the air rising in the tube 124 as a result of the discharge of the same from the tube 126 and is discharged at the discharge members 130 to mix with further incoming sewage. The liquor rising in the tubes 124 is a slurry of part of the accumulated activated sludge and processed sewage.
Processed liquor, together with some activated sludge, also passes out of the first chamber 121 into the second chamber 122, rises therein and passes out of the reactor 110 through tube 132.
The partial separation and accumulation of the solids along the inner wall of the container 116 under the centrifugal action of the rotating liquid decreases the tendency thereof to enter the second chamber 122 and hence decreases the tendency thereof to be discharged from the reactor 110 with the effluent in tube 132, thereby decreasing the quantity of solids requiring separation by later clarification and decreasing the amount of sludge to be recycled from the clarifier 112 to the reactor 110. The partial separation and accumulation of solids also increases the retention time of the suspended solids in the reactor 110.
The result of the rotation of the suspended solids is a plug flow pattern for the reactor liquor, oriented downwardly along the vertical axis of the reactor 110 and through the first chamber 121. As the liquor and solids flow downwardly in the first chamber 121, substantially all the suspended, colloidal and dissolved organic materials contained in the sewage are adsorbed by the activated sludge. The adsorbed organic material is biologically oxidized by the microorganisms, while organic nitrogen is converted to ammoniacal nitrogen and ammoniacal nitrogen is biologically oxidized by the microorganisms to nitrites and nitrates.
The biological oxidations deplete the absorbed oxygen to a level at which the heterotropic microorganisms in the activated sludge cause endogenous respiration and anaerobic conversion of nitrite and nitrate to nitrogenous gases, the adsorbed organic carbon increasing the rate of denitrification.
The dissolved oxygen concentration gradient is affected by the biological reactions and the downward velocity of the liquor through the first chamber 121, the latter being regulated by the volume of air introduced by the gas feed tube 126 to the riser tube 124.
The biological reactions and adsorption in the chamber 121 also decrease the phosphate content of the sewage to a significant degree.
Since the sludge entering the riser tube 124 has a very low dissolved oxygen content, there is a considerable driving force for oxygen transfer at this point, resulting in rapid and efficient absorption of oxygen by the biomass and saturation of the mixed liquor-sludge with oxygen prior to discharge from the elements 130. The riser tube 124 therefore may be regarded as a "flash aerator".
The velocity of the air-lifted sludge in the riser tubes 124 results in numerous collisons of solid particles, resulting in their abrasion and a higher rate of hydrolysis of recycled suspended solids. This effect may be enhanced by the addition of granular abrasive solids, such as granular activated carbon to the reactor liquor.
The reactor 110 in this embodiment, therefore, replaces the reactor 10 and the aeration tower 44 utilized in the embodiment of FIG. 1, simplifying considerably the equipment and hydraulic requirements of the system. The reactor 110, therefore, achieves the following functions within a single, compact unit: subdivision of suspended solids by abrasion in the flash aeration riser tube 124, hydrolysis of suspended solids, separation of dissolved organic matter from the waste water by adsorption on activated carbon and microbial cells, biological oxidation of adsorbed organic matter, biological conversion of organic nitrogen to ammoniacal nitrogen (for ammonification), biological oxidation of ammoniacal nitrogen to nitrite and/or nitrate nitrogen (or nitrification), biological reduction of nitrite and nitrate nitrogen to nitrogenous gases (or denitrification), biological reactivation of activated carbon, oxygenation of settled microbial cells and activated carbon and stripping of volatiles.
The design of the reactor 110 shown in FIG. 3 allows a number of beneficial effects, including efficient utilization of oxygen from air, efficient mixing of activated sludge, high concentration of sludge for bio-reactions, optimum concentration gradient of dissolved oxygen to accommodate organic matter biooxidation, ammonification, nitrification and denitrification in one reactor, mechanical grinding of suspended solids by high velocity of sludge in flash aerators, utilization of surface media to increase rate of reaction and elimination of air pollution.
The effluent from the reactor 110 containing some entrained activated sludge and suspended solids in tube 132 is passed by line 133 to the clarifier 112. The liquor in line 133 is fed into the clarifier 112 substantially tangentially of the inner wall of a container 137 by pipe 139 at the intended liquid level in the container 137.
An inverted funnel-like member 138 is located within the container 137 and defines therewith a first chamber 140 between the funnel-like member 138 and the container 137 a sludge accumulation chamber 142 and a settling chamber 144 inside the funnel-like member 138.
The funnel-like member 138 includes a skirt portion 146 concentric with and spaced inwardly from the inner wall of the container 137, a truncated cone portion 148 and a throat portion 150 also concentric with the container 137 and extending upwardly above the intended liquid level in the container 137.
The sludge accumulation chamber 142 also is defined by a conical insert 152 engaging the inner side and base of the container 137 whereby the sludge accumulation chamber has a decreasing diameter towards the base of the container 137. A hollow riser tube 154 is positioned concentrically of the container 137 and extends through the chamber 144 and into the sludge accumulation chamber 142 to a location spaced immediately upwardly of the base of the container 137, the riser tube 154 flaring outwardly at its lower end.
A gas feed tube 156 is situated within the riser tube 154 to feed air, oxygen or other gas rich in molecular oxygen into the riser tube 154 adjacent the lower end of the riser tube 154 to lift sludge out of the accumulation chamber 142 and aerate the same during the lifting, prior to discharge from the clarifier 112 for recycle to the reactor 110 by line 158.
The feed of the liquor by line 133 and discharge pipe 139 to form a rotating liquid body in the chamber 140 results in separation of suspended solids from entrained gas bubbles by the centrifugal forces. The gases may be vented from the clarifier 112 through vent 166.
Suspended solids tend to move radially outwardly to accumulate adjacent the inner wall of the container 137 while the gas bubbles tend to move inwardly and upwardly, producing a thin layer of foam at the surface of the rotating liquor. The foam is consistently broken by the incoming stream, so that it never overflows and hence any potential foaming problem is overcome. The solids move downwardly through the chamber 140 towards the sludge accumulation chamber 142 under the influence of gravity and the velocity of liquid flow through the chamber 140.
The separation of the gas bubbles in the first chamber 140 as foam on the top of the liquor prevents substantially the presence of such bubbles in chambers 142 and 144 where they may disrupt the sedimentation of the sludge.
By providing time for efficient gas separation in the first chamber 140, conditions also arise for completion of the biooxidation reactions and denitrification by the mixed microbial population. Granular or powdered suspended solids, for example, activated carbon, may be used to increase the reaction rates and to increase the density of the sludge to improve the rate and efficiency of suspended solids separation.
The sludge is separated from the processed waste water by sedimentation in chamber 144 with further settling and compression of the sludge in chamber 142.
The clarified effluent leaves the clarifier 112 by pipe 162 communicating with the third chamber 144 but out of communication with the first chamber 140 and by line 163. The clarified effluent in line 163 may be subjected to additional treatment, as described above in connection with the effluent in line 40 in the embodiment of FIG. 1.
A pipe 164 may communicate with the sludge accumulation chamber 142 for removal of excess sludge therefrom, if required.
The clarifier 112 therefore achieves a variety of functions in the purification of the waste water, including completion of the biological reactions, biological flocculation, sludge coagulation and suspended solids separation by settling, and provision of sludge in preaerated form for passage to the reactor 110.
The design of clarifier illustrated in FIG. 4 provides a number of beneficial effects in the treatment of the waste water, including efficient separation of scum and foam, reactor volume for completion of biooxidation reactions and denitrification, gentle mixing of mixed liquor suspended solids to achieve biological flocculation and coagulation compression of settled sludge, reaeration of recycled settled sludge and elimination of the need for a sludge recirculation pump.
The operations of the reactor 110 and the clarifier 112 balance the quantity of sludge present in the system and contain the sludge within the reactor 110 and clarifier 112, sludge being substantially absent from the clarified effluent in line 162.
The process of the invention involves several features which enable three different operations to occur in one reactor, the three operations being biological oxidation of organics and nitrogenous materials, nitrification and denitrification in the reactor. There is an efficient and rapid separation of dissolved organic material from the waste water by adsorption on activated carbon and microbial cells which provides ideal conditions for nitrification and denitrification. The overall retention time is considerably less than in the prior art systems.
Activated carbon provides the adsorption capacity of the system for removal of organics in the initial stages of the operation, provides for even redistribution of carbonaceous materials in periods of high and low BOD loadings due to adsorption and desorption of organics in relation to BOD concentration, as a catalyst supports oxidation reactions, and provides a porous structure supporting microbial growth. The resulting sludge has excellent settling properties permitting efficient separation of suspended solids and a fast build-up of the mixed microbial population responsible for the biological reactions.
The oxygen required for the biooxidation reactions and for the reactivation of activated carbon is provided by aerating the settled sludge. Since the concentration of sludge is generally above 8,000 mg/l., the transfer of oxygen from air to the microbial cells and activated carbon is substantially direct and less through molecular diffusion through water than is the case in other biological processes. Consequently, the oxygen mass transfer rates to microbial cells are higher, the required aeration volume smaller and the oxygen utilization better than in conventional systems.
The invention is illustrated further by the following Examples:
Domestic sewage was treated on a pilot plant scale using an apparatus of the type illustrated in FIG. 1 at a flow rate of about 10,000 gallons per day over a continuous period of 60 days. The apparatus was unattended in this period with the exception of the taking of samples for analysis. The reactor 10 and the clarifier 28 were of the same dimensions having a volume of 118 cubic feet. The aeration tower 44 had a volume of 75 cubic feet and an effective aeration volume of 53 cubic feet.
Domestic sewage, which was prescreened to remove gross solids, was fed at a flow rate varying between 5 and 6 gallons per minute to reactor 10 which contained 125 lbs. of activated carbon. The superficial contact time, calculated as the ratio of volume of reactor to flow rate of sewage, varied between 2.4 and 2.9 hours. Over the test period, the constitution of the treated sewage varied widely.
The liquid effluent from the reactor 10 which was obtained at a rate of 5 to 6 gallons per minute and was tested from time to time for various contaminants, was passed by line 26 to the clarifier 28 containing 125 lbs. of activated carbon, resulting in a superficial contact time for the liquor therein of 2.4 to 2.9 hours. The liquid effluent from the clarifier 28 in line 40 was tested from time to time for the concentration of contaminants therein, and was passed to a deep bed activated carbon filter, the effluent from which was tested for contaminants.
The quantity of dissolved oxygen fed to the reactor 10 was about 8 mg/l. while the quantity leaving the reactor was less than 1 mg/l. For the clarifier 28, the quantity of dissolved oxygen fed was about 3 to 8 mg/l while the quantity in the effluent was about 1 to 4 mg/l.
The sludge from the reactor 10 and the clarifier 28 was passed by lines 42, 46 and 48 to the aeration tower 44 wherein it was subjected to countercurrent contact with air, the air consumption being about 30 to 40 SCFM, the sludge concentration being greater than 8,000 mg/l and the superficial contact time of the sludge in the aeration tower 44 being 1.1 to 1.33 hours. During the 60-day run, there was no withdrawal of sludge or addition of activated carbon.
The results obtained over the last 15-day period of the first 30-day pilot plant operation are summarized in the following Table I and results from the 60-day operation are summarized in Table II:

Based on the above experimental results, a comparison was made of the process of this invention and that of the three-stage biological system discussed above and disclosed in Barth et al., JWPCF vol. 40, No. 12, p.2040 (1968), with regard to certain important parameters. This comparison is reproduced in the following Table III:

Additionally, the present invention does not require the addition of methyl alcohol or other chemical source of energy for the denitrification reaction. The advantages of the present invention over the prior art process are readily apparent from the above Table III.
Utilizing a structure in accordance with the embodiment of FIGS. 2 to 4, raw primary treated domestic sewage at a rate of 4,000 gallons per day was treated over a continuous period of 38 days. The apparatus was unattended with the exception of the removal of samples of effluent in line 163 for analysis.
The constitution of the sewage varied widely over the test period as did the operating conditions. The variations in these parameters together with the average removal efficiencies for various contaminants appear in the following Tables IV, V and VI, respectively:
TABLE IV______________________________________Concentrations of Contaminants in Sewage Raw Sewage Contaminant Range Average______________________________________Suspended solids mg/l (S.S.) 63 to 199 122BOD5 mg/l 77 to 217 124Total organic carbon (TOC) mg/l 61 to 124 93Soluble organic carbon (SOC)mg/l 27 to 53 37PO4 mg/l 14 to 29 20Ammoniacal nitrogen mg/l (NH3 -N) 12 to 35 20Total nitrogen mg/l (TKN) 18 to 35 28Nitrite and nitrate nitrogen mg/l 0.2 to 4.3 2.5(NO3 -N)Total dissolved solids mg/l (TDS) 470 to 590 503Turbidity JTU 54 to 125 75Coliform N/100 ml �4 � 107 107______________________________________

It will be seen, therefore, that the process of the present invention is able to remove substantially completely biodegradable carbonaceous, nitrogenous and suspended solids contaminants from waste water containing such contaminants while avoiding the production of substantial quantities of excess biological sludge, the necessity for external reactivation of carbon and the use of chemicals for clarification. In addition, the process of the present invention may be practised in equipment requiring little space and essentially no maintenance. Capital and operating costs, therefore, are significantly lower than with any other known waste treatment.
Modifications are possible within the scope of the present invention.

Florida Teaching Certification Overview: Become a Certified Teacher
More Information:
A certified teacher in Florida will enter a vibrant, strongly connected group of qualified educators. To be successful, it's important to know the process needed to earn your Florida teaching certification.
Requirements for Certified Teachers in Florida
The first step in becoming a certified teacher in Florida is completing a state-approved teacher preparation program. The state has approved the bachelor degree programs at multiple colleges and universities as thorough enough for its teachers. Completing this training earns you a Temporary Certificate.
In order to attain full certification, the state of Florida requires its teachers to take the Florida Teacher Certification Examination. This test is broken down into three portions: general knowledge, professional education and educational leadership. To become a certified teacher in Florida, you must pass all three.
In addition, some teachers may be required to take subject area examinations. Most teachers, regardless of their specialty area, will fall into one of the subject area examination categories. When you apply for your Temporary Certificate, the Florida Bureau of Educator Certification will tell you which subject area tests you need to complete.
Florida Jobs for Licensed Teachers
Your Temporary Certificate is valid for three school years. This gives you the chance to take the required certification tests while you are teaching and earning an income. It allows you to get a job as a classroom teacher before finishing the certification process. This initial certificate is not renewable, so you will need to complete the certification process within the three years allotted for the Temporary Certificate.
Upon successful completion of the Florida Teacher Certification Examination and background check, you will receive a Professional Certificate. This is the highest available certificate for teachers in Florida, and it is valid for five years.
When you are ready to renew your certificate, you will need to show proof that you have taken six semester hours of college credit, or something equivalent. Teacher in-service points can be traded in for credit hours if you are not interested in pursuing another degree.
If you are interested in becoming a certified teacher in Florida, you may want to look into the various grants and loan forgiveness options available to teachers in this state. For instance, certain subject areas are considered Teacher Shortage Areas (TSAs) throughout the state. Because there is a shortage of teachers in these fields, the Department of Education offers grants to those studying education who are willing to teach these subject areas in the state of Florida. While the teacher shortage areas change annually, they commonly include autism teachers, deaf/hearing impaired educators and special educators for students with intellectual disabilities.
If you are planning to study in one of these disciplines and are willing to commit a period of your professional career to a teacher shortage area, Florida has options for you. This could allow you to receive a federal grant for a portion of your education expenses through the Teacher Education Assistance for College and Higher Education Grant Program. In addition, up to 100 percent of your Federal Perkins Loan may be cancelled in return for teaching full time in one of these shortage areas.
Teachers in Florida find it to be an excellent state in which to work, and your Florida teaching certification offers you this chance. The state has higher-than-average graduation rates of over 70 percent, with an average dropout rate of just 3.5 percent. The state also has a vibrant online community of educators led by the Deputy Director of Educator Relations, which makes staying connected with other teachers easier. Access to the Florida Teacher Community is free if you hold a Florida teaching certification.
Teaching License Reciprocity in Florida
If you're licensed to teach in another state and move to Florida, you may be able to take advantage of teaching license reciprocity. This makes it easier to transfer the license from one state to the next. To learn more about reciprocity, visit Teaching License Reciprocity Explained.
Disclaimer: Licensing requirements are subject to change. Please visit your state board of education to check for recent revisions to teaching license requirements.< show all "Licensing" articles

Westin Resort & Spa, Los Cabos Review
Built by prominent Mexican artist Javier Sordo Madaleno, the colorful architecture makes thisWestin more memorable than some of the others in the Corridor. The recently renovated rooms, some set high above a man-made beach, are among the best in their price range, and have Westin's trademark Heavenly Beds, with cushy pillows and comforters. The dramatic setting of the hotel means you'll get plenty of exercise moving from one area to another, which is good for some and less appealing for others. The restaurants receive mixed reviews, with most leaning toward the expensive but mediocre in terms of satisfaction.

An article for teachers and pupils that encourages you to look at the mathematical properties of similar games.
This article for teachers describes several games, found on the
site, all of which have a related structure that can be used to
develop the skills of strategic planning.
Think of a number, add one, double it, take away 3, add the number
you first thought of, add 7, divide by 3 and take away the number
you first thought of. You should now be left with 2. How do I. . . .

patterns of play are similar.
The sum of the numbers 4 and 1 [1/3] is the same as the product of 4 and 1 [1/3]; that is to say 4 + 1 [1/3] = 4 � 1 [1/3]. What other numbers have the sum equal to the product and can this be so for. . . .
Square numbers can be represented as the sum of consecutive odd
numbers. What is the sum of 1 + 3 + ..... + 149 + 151 + 153?

Confirming months of rumors, Bill Fulton, planning director for the city of San Diego, submitted his letter of resignation, according to a memo released Friday by Mayor Kevin Faulconer's office. Hired last summer by then-Mayor Bob Filner, the city's top planner will step down Aug. 30 to take a position as the director of the Kinder Institute for Urban Research at Rice University in Houston.
Here's an update to this week's cover story in CityBeat about Lorne "Hammer" Jones, written by the author of the story, Andrew Gumbel:
Lorne Jones, the convicted former customs inspector whose case is subject of CityBeat's July 30 cover story, is reporting to federal prison today, more than three weeks ahead of the self-surrender date of Aug. 22 imposed by the San Diego District Court, and will serve no more than one-third of the time to which he was sentenced in March.
"I'm tired of fighting," Jones told CityBeat from Reno, an hour's drive from the Herlong Federal Correctional Institution, where he has been assigned by the Bureau of Prisons (BOP). "There's things I could still do, but I just want this to be over."
Jones said he believed he was innocent of the charges on which he was convicted. He was further upset that the BOP was assigning him to a medium-security facility when a sentencing agreement worked out with the prosecution last month—and since made public by the court in an amended judgment—specifically called for the low-security prison at Taft, in Kern County, which is several hundred miles closer to his family in San Diego.
The amended judgment is dated July 11, the date of the hearing that Jones and his lawyer were clearly preparing for, and it cuts his time from 90 months, or seven-and-a-half years, to 30 months, or two-and-a-half years. Technically, he's now sentenced to serve 30 months on each of the two counts—conspiracy and attempted marijuana-smuggling—on which he was convicted, but the agreement makes clear the two sentences are to be served concurrently.
Jones said he expected to be out in less than two years, allowing for time served after his arrest and before he made bail, and assuming he wins credit for good behavior.
The reason why his sentence was abruptly cut by two-thirds, even though he waived his right to appeal, remains shrouded in mystery. Nominally, the reason for the reduced sentence was Rule 35 (b) of the Federal Rules of Criminal Procedure, which refers to a circumstance in which a defendant offers "substantial assistance in investigating or prosecuting another person." But a legal source familiar with the case told CityBeat the reason was something more unusual, "like lightning striking"—curiously, the very phrase the government used at trial to describe one of its strongest pieces of circumstantial evidence.
Volunteers with Books for Prisoners are trying to figure out how to cram dozens of boxes of donated books—tomes that had once filled more than 600 square feet of space—into a storage room one-sixth that size. The UCSD student-run group, which, since 2001, has provided prison inmates with free books, was told last month that they had to vacate the space they'd been using for almost six years.
It's no secret that San Diego needs all the help it can get when it comes to repairing aging water pipes and sewer lines. With more than a billion dollars in unmet infrastructure needs, officials have been looking under every couch cushion to keep the disrepair to a minimum.
What might seem odd, however, is that the city has ostensibly given up access to tens of millions of dollars of infrastructure grants and loans provided routinely by the state. Despite warnings from Sacramento officials, in June 2012, San Diego voters passed a ballot measure, Proposition A, that's in direct conflict with state law.
The San Diego Housing Commission next week will propose to the City Council's Smart Growth and Land Use Committee a new plan for funding affordable housing and making market-rate housing cheaper.
Here's a draft of the report that will go to the committee. CityBeat will follow up with some analysis of the details soon.
The proposal stems from a battle earlier this year: The City Council passed an increase to a fee that developers of commercial properties pay to help finance affordable housing, but opponents of the fee—calling themselves the Jobs Coalition—waged a successful campaign to get a referendum on the ballot to repeal the increase, and the City Council conceded defeat, repealing its own ordinance.
The plan is being billed as a compromise between the Housing Commission, which spearheaded the effort to increase the affordable-housing fee, and the Jobs Coalition, and Mayor Kevin Faulconer is on board.
"I promised to bring housing advocates and the business community to the table to work on a compromise and that's exactly what happened," he said in an written statement provided by a spokesperson. "This deal strikes a fair balance that provides more funding for affordable housing without stifling economic development."
This morning, KUSI aired a live interview with District Attorney Bonnie Dumanis, during which she discussed a controversial letter of recommendation that she wrote for the son of Susumo Azano, who's been charged by federal authorities with making illegal contributions to Dumanis' campaign for mayor of San Diego. Azano's son was seeking admission to the University of San Diego.
One of San Diego County's most touted advisory groups has failed to follow state open-meeting laws.
Since its inception in June 2011, the San Diego County Regional Human Trafficking and CSEC (Commercial Sexual Exploitation of Children) Advisory Council hasn't posted agendas or made its meetings known to the public, Steve Schmidt, spokesperson for county Supervisor Dianne Jacob's office, confirmed Tuesday. No information about the advisory council's meetings can be found on the county's website; nor is any information listed on the "Committee Fact Sheets" web page.

Dog ban row continues in St Ives
As a consultation about banning dogs from some St Ives beaches nears its end, dog owners have come together to fight the plans
As a consultation about banning dogs from some St Ives beaches nears its end, dog owners have come together to fight the plans
A consultation on plans to ban dogs from some of Cornwall's most popular beaches has reignited a massive debate about the matter.
People get to have their say on plans to ban dogs from some of Cornwall's most popular beaches.
Dog owners in South Hams are being warned to keep their pets away from a white substance that's washed up along the Salcombe Estuary.
The Palm Oil like material is similar to the substance found on Cornish beaches in October. The council say teams will be out to clear the North and South Sands beaches this morning.
Devon and Cornwall police's dog section have bred their own pups for the first time.
German Shepherd Ruby gave birth to the litter earlier this week and the results are now being shown on the internet. It's hoped that when the dogs are old enough they'll be trained as police dogs.
After an initial period with their mother, the puppies will go to family homes for twelve to eighteen months before being assessed for training. If successful, they'll then embark on an intensive 13-week course.
You can watch them live here
Restrictions on people taking their dogs to the Eden Project have been lifted this weekend for the first time. Until now, only registered assistance pets have been permitted. But animals won't be allowed in any building apart from through the Visitor Centre.
Eden's Operations Director Ian Williams said: "Lots of visitors have asked us if we would consider letting dogs in. We will see how Dog Weekend at Eden goes and how well it is received by dog owners and general visitors and will then make a call on whether we have more dog days in future."
Devon and Cornwall Police are trying to track down the offspring of three pitbull-type dogs they seized from a couple in Barnstaple.
It's thought there could be more than a hundred of them across the country.
Steven and Tracey Tewkesbury are awaiting sentencing for possessing and offering to supply dangerous dogs.
A controversial order banning dogs from St Ives' beaches comes into affect today.
The 24 hour ban applies to Porthgwidden,Porthmeor and Porthminsterwhile an 8am to 7pm ban also comes into force on Harbour beach.
St Ives Dog Owners Group who oppose the ban are planning a demo this weekend. There will be similar dog bans coming into place on other beaches in the region, including Sidmouth and Instow.
Dog owners in North Devon are the latest to react with anger to plans to ban their pets from a beach. Dozens attended a meeting in Instow this morning where they claimed the ban was being forced through.
Just two months ago councillors in St Ives infuriated many locals when they voted through a dog ban.
Parents and teachers say they've been amazed at how children who needed some extra help at school with things like reading and confidence have improved thanks to working with a dog.
The North Devon based charity Dogs Helping Kids is now training owners and their animals across our region as by word of mouth demand for their volunteer service has exploded.
Our correspondent Seth Conway reports:
Controversial plans to ban dogs from the main beaches in St.Ives during the summer months will go ahead next year.
The move was backed by the town council last night. But dogs will be allowed on the harbour beach early in the morning and in the evening.
The question of whether or not to exclude dogs from the main beaches at St Ives in Cornwall is being hotly debated later.
If it goes ahead, the ban will come into force from next summer.
St. Ives Town Council will decide tonight on whether to ban dogs from beaches in the town from next summer.
The proposal is for a daytime ban on harbour beach in summer and a total summertime ban on the other main beaches. Dog walkers in the town are angry that the suggested alternative beaches are unsuitable at high tide.

you are viewing a single comment's thread.
This is one of the better, more informative strings I've read in quite awhile...on any board.At the end of the day, whenever that day may be of course, fundamentals resolve stock prices. In between, however, many other factors drive the price. My feeling is that right now this stock is still way off the radar and hasn't been influenced by any speculative or technical phenomena whatsoever. Instead, it's almost been trading like a bond with decisions based on net cash, discounted NOLs and "flights" in and out of safety although the meek volume over the past couple of years shows there weren't many people on those flights.When this stock gets some mindshare I expect it to move both above and below whatever fundamental price it should garner. In short, I expect to see it trade above $10 or better and trade a little below where it is today. Mix some speculators in with the stock's miniscule float which is effectively lowered even more by Kanders' position and who knows how high the price could go short term....as in a period of several days in a row.For the next year, I think the price will be driven much more by top line growth guidance rather than earnings and bottom line fundamentals, at least until growth has stabilized or a revenue target is missed.Just my opinions.
I agree, there will likely be more volatility even now as it has gotten more attention but especially once it gets listed. While the swings may be larger, fundamentals are key to keep one's bearing through it all. I don't think about the fundamental value as a destination into the ever extending horizon but rather a centerpoint or mean around which we will see the swings occur. Having a good peg as to where it exists inevitably pays hansomly... as long as you keep your emotions straight. And yes, I think topline growth will be key here but this stock stands a major correction in either direction depending on where margins come out.
