SR-4040 module compose by the stainless steel housing and the changable hollow fiber UF membrane. it can do forward flush and back washing and the chemcial washing

 when operation, it should Avoid sudden large changes on pressure, it should with slow up or down on pressure

1 center pipe structure design make the  water distribution is more even and better back washing effect.

2. both each side output water, makes it good back wash performance

3. Quick joining piping joint design,easy and fast installation, high leakproofness

4.Stainless steel band structure, deformation, no leaking

5. Membrane material is pollution resistance, high strength, hydrophilic modified PVC.

6.stable water flow, high anti-pollutaion, high  mechanical strength

7. can adopt 200ppm residual chlorine in short time, suitable PH 2-13

8 absolutely removing bacteria, output water flow turbidity ＜0.1NTU

9.Cross flow design, eliminate the dirty and block and improve the life

10. DI15<1  (testing raw water turbidity ＜20NTU)
