can easily be offset by increasing the filter surface with a modular structure. In gas phase filtration different deposition mechanisms are operative, so that particles having sizes below the pore size of the membrane can be retained as well. Membrane Classification Bio-Membrane is classified in two categories, synthetic membrane and natural membrane. synthetic membranes further classified in organic and inorganic membranes. Organic membrane sub classified polymeric membranes and inorganic membrane sub classified ceramic polymers. Synthesis of Biomass Membrane The composite biomass membrane Green membrane or Bio-membrane synthesis is the solution to protected environments which have largely comprehensive performance. Biomass is used in the form of activated carbon nanoparticles, like using cellulose based biomass coconut shell, hazelnut shell, walnut shell, agricultural wastes of corn stalks etc. which improve surface hydrophilicity, larger pore size, more and lower surface roughness therefore, the separation and anti-fouling performance of membranes are also improved simultaneously. Fabrication of pure biomass based membrane A biomass-based membrane is a membrane made from organic materials such as plant fibers. These membranes are often used in water filtration and wastewater treatment applications. The fabrication of a pure biomass-based membrane is a complex process that involves a number of steps. The first step is to create a slurry of the organic materials. This slurry is then cast onto a substrate, such as a glass or metal plate. The cast is then dried, and the resulting membrane is then subjected to a number of treatments, such as chemical or heat treatments, to improve its properties. One of the challenges in the fabrication of biomass-based membranes is to create a membrane with the desired properties. Equipment & Instrument used in process List of Instruments Used in Membrane synthesis procedure as follows: Centrifuge Casting Machine Plane casting glass Magnetic Stirrer Glass ware: Beakers, measuring cylinders, flask etc. Oven Mortar and pestle Membrane Characterization After casting and synthesis of membrane there is need to characterize the prepared membrane to know more details about membrane parameters, like pore size, function group, material properties etc. It is important to know membrane properties so we are able to remove and treat a particulate pollutant, which causes pollution in the environment. For characterization following different instruments is used: Scanning Electron Microscope (SEM) Transmission electron Microscope (TEM) Fourier Transform Infrared Spectroscopy (FTIR) X-ray Diffraction (XRD) Liquid–Liquid Displacement Porosimetry (LLDP) Biomass Membrane Applications Water treatment Water treatment is any process that improves
