Ultrafiltration is a kind of pressurized membrane separation technology, that is, under a certain pressure, the small molecule solute and solvent through a certain aperture of special film, but the large molecule solute can not pass through, stay in the membrane side, so that the large molecule material has been partially purified.The principle of ultrafiltration is also a membrane separation process. Ultrafiltration USES a pressure active membrane to trap colloids, particles and substances of relatively high molecular weight in water under the action of external force (pressure), while water and small solute particles pass through the membrane separation process.The material with molecular weight of 3x10000-1x10000 can be trapped by micropore screening on the membrane surface.When the treated water passes through the membrane surface at a certain velocity with the help of the external pressure, water molecules and solute with the molecular weight less than 300-500 penetrate the membrane, and particles and macromolecules larger than the membrane hole are trapped due to the screening action, so that the water can be purified.In other words, when the water passes through the ultrafiltration membrane, most colloidal silicon contained in the water can be removed, and a large number of organic matters can be removed.
