The intercepted substances are mainly proteins, various □, bacteria, viruses, latex, microparticles. The filtration precision is 10-4cm~10-7cm. The liquid is separated by ultrafiltration membrane with different pore diameters. The molecular cutting capacity (CWCO) is generally 60 million~500000, and the pore diameter is 100nm (nanometer).
The substances passing through the microporous filter membrane are mainly water, solution and dissolved substances. The intercepted substances are mainly suspended solids, bacteria and particles. The filtering precision is 0.2cm, 0.5cm, 1.0cm, 2.0cm, 3.0cm, 5.0cm and 10.0cm. Its important characteristics in the filtration field are:
All particles larger than the mesh are intercepted on the surface of the membrane, which overcomes the requirement that conventional deep filter media filtration cannot reach the "absolute value", while microporous filter membrane is the selective material of the filter tending to "absolute value".
Uniform aperture, high filtering accuracy
The pore diameter of microporous filter membrane is very uniform, so it is a homogeneous membrane, which is obviously different from reverse osmosis and ultrafiltration. The ratio of the maximum aperture to the average aperture is generally 3~4, and the aperture distribution is basically normal distribution. Therefore, it is often used as a means to ensure *, with high filtering accuracy and separation efficiency. High porosity and fast flow rate.
