Ultrafiltration membrane technology is under the action of a certain working pressure, water flows through the surface of the membrane, solutes larger than the pore size of the membrane are blocked, and the aqueous solution flowing out is called a concentrated solution. The whole process of ultrafiltration membrane technology is realized under fluidity conditions. The impurities in the water accumulate on the surface of the membrane, which will cause the pollution of uf membrane module, and the characteristics of the membrane can be repaired after cleaning.
The main categories are flat type, tube type, roll type, hollow chemical fiber type, etc. Concentration polarization is a natural phenomenon in the entire process of membrane separation technology. The countermeasures implemented at this stage are to increase the water flow speed on the membrane surface, reduce the thickness of the adhesion layer, immediately bring the concentration of the intercepting substance into the water, and take physical or chemical cleaning countermeasures.
2. The basic principle of ultrafiltration membrane technology filtration technology
The application of ultrafiltration membrane technology in the field of water treatment is becoming more and more common. The ultrafiltration can provide high-efficiency suspended solids, colloidal solutions, organic chemical biological macromolecules, bacteria, microbial bacteria and other residues.
