[Name] Waste Water Treatment Research Pilot Plant [Description] 
The Water Treatment Research Pilot Plant is located at the south end of the Hydraulic Laboratory and has a design flow of 76 L/min (20 gpm) with ten unit processes, including rapid mix/coagulation, flocculation, sedimentation, filtration, ozonation, absorption, ion exchange, air stripping, and membrane filtration. Removals of contaminants can be done on any combination of unit processes or any unit processes can be isolated for more fundamental research. On line sensors include: Hach streaming current, Hach turbidimeters, Met One particle counters, and Signet pH, temperature, conductivity, and pressure. The facility is controlled by a MicroDac board with micro-relays to control pumps and valves with unit conversions of 20 mv analog signals to digital calibrations. The facility is operated by a PC computer with backup power and alarm system to provide alerts concerning problems. A break in a water line, for example, would result in an orderly shutdown. The plant can be operated continuously for indefinite periods and can be operated unattended as needed. The computer is connected to the CSU Net for transfer of data, and for remote monitoring and control. The pilot plant has been utilized on a number of research projects since it's construction in 1992, including projects sponsored by the US Army Corps of Engineers, the USEPA, and the American Water Works Association Research Foundation. The pilot plant has been used regularly in teaching design of water treatment processes.
