Membrane filter technique was presented as a substitute for the most credible number technique for microbiological examination of water samples. The membrane filter technique is used by passing the taster through the membrane using a filter pipe and void system. Any bacteria in the taster are intended on the outward side of the membrane. The membrane is then placed on a distinct plate with its stuck bacteria comprising a pad soaked with a suitable medium. The passage of comestibles through the filter during gestation eases the growth of organisms in the form of gatherings, on the topmost surface of the membrane. MFT technique is an active acknowledged technique for testing fluid samples for microbiological impurities. Membrane filters are used expansively in the laboratory and industry to disinfect liquefied materials.
