One more question, do you pre-treat the water by UF for RO? If that is the case then you cannot avoid UF membranes as SDI will be much higher to clog your RO Membranes if you bypass UF Membranes.
In addition, DOW UF has an exceptional feature which others UF membrane manufactures have, that is Air Scouring, you can increase time of Air Scouring to eliminate the suspended particles accumulation and Air Scouring is also a Scheduled Task while it goes to Backwash after 12 hrs interval.

HI
I agree with Mr.Ahamed,
it is very important which type of raw water you used, if surface water and sea water is raw water used in your system ,the UF pretreatment was suitable choice.

02: Yes i agree but only problem UF system is old & due not proper operation UF membrane Block, required whole UF system rehabilitation.
