Ultrafiltration Technology For Wastewater Polishing

Ultrafiltration technology can effectively separate colloidal substances and small suspended particles, and has certain removal effects on microorganisms, bacteria and other substances in water.It can effectively purify water. Compared with traditional water technology, ultrafiltration technology has many advantages, such as convenient process operation, low energy consumption, good purification effect and recyclability. It is widely used in domestic sewage treatment and seawater purification.

The principle of ultrafiltration membrane: under the action of high pressure, the solvent and some low-energy solute in the solution can reach the other end of the membrane through the tiny pores on the membrane, which has an intercepting effect on the molecular and high-quality dissolution. Separating the substance, while the surface of the film has chemical properties, intercepting a small amount of material. When the solution is ultrafiltered, pressure is applied to the solution to pass the inorganic salt, water and low molecular substances when the solution passes through the ultrafiltration membrane, and the high molecular substance and the colloid are intercepted to achieve the purpose of purifying the water.
