PS Hollow Fiber Ultrafiltration Membrane

Our hollow fiber ultrafiltration membrane is made of excellent polysulfone, a sort of high polymer material. The molecular weight cut off (MWCO) of ultrafiltration membrane for water purification is 67000 Dalton. That means the pore size of our PS membrane is just 1/10000 the diameter of a piece of hair. Thus our product can be used to remove fine impurities, organic matters, microorganisms, bacteria and other hazardous substance from water. Besides standard PS hollow fiber ultrafiltration membrane with diameter ranging from 90mm to 225mm, we can also offer customized product based on customers' special requirements.

1. Powerful Chemical Resistance

With powerful chemical resistance, our PS ultrafiltration membrane can work normally under the condition with PH range of 12-13. During chemical cleaning, it can endure high-density acid and alkali, and has fine flux recovery capacity.

2. Good Filtration Effect
Unique double finger structure makes our product have higher anti-fouling performance and better filtration effect. Our PS hollow fiber ultrafiltration membrane can effectively remove impurities such as suspended solids, colloids and bacteria from water to get high quality permeate water.

3. High Mechanical Strength
Due to high mechanical strength, our membrane for ultrafiltration can be backwashed with high flow water without damaging the fibers. Thus our product has longer service life.
