Ultrafiltration system for water purification
Ultrafiltration is a low pressure membrane separation technology. The filtration process is driven by the pressure difference between the two sides of the membrane. A pure mechanical screening process in which the membrane pore size has different interception rates for materials with different molecular weights. Dissolved substances and those with diameters less than the membrane pore size will pass through the ultrafiltration membrane with the permeation liquid. Non-permeable substances will gradually be concentrated and discharged into the liquid. Therefore, the producing water contains water, ions and small molecules, while colloidal substances, particles, bacteria, viruses and protozoa will be removed from the membrane. Ultrafiltration membrane can be used repeatedly and can be cleaned with chemical cleaning agent.
Equipment parameters:
The operating pressure of ultrafiltration is generally 1~2.5bar.
With a molecular weight of 1000 ~ 500,000 Dalton,
Filtration accuracy 0.002~1 m, medium temperature 5~80 ℃,
The PH range is 2 ~ 10.
Optional equipment: 0.5~50m3/h.
