Hi Ali, what do you mean with maintenance costs? Do you mean frequently replacement of UF membranes/modules ? What is the application of UF? Is UF used as pre-treatment System for RO? Do you have any P&ID for review? What is the UF feed water and outlet water quality concerning turbidity, TSS & SDI? Do you have any UF projection from DOW?

I would recommend to check and adjust the time intervals for backwash and CEB and also the related chemicals for CEB and/or CIP. Do you use also a recommended strainer (150 micrometer) at the UF inlet? It seams that the UF is overloaded!

Yes UF for RO...... But SDI is also in normal range.

only problem UF system is old & due not proper operation UF membrane Block, required whole UF system rehabilitation.
