How often should RO membranes undergo chemical CIP (Clean-in-Place) washing?

It depends on feed-water turbidity and scaling tendency; many plants clean every 3 to 6 months, or when normalized permeate flow drops about 10–15%. Low- and high-pH CIP chemicals remove scaling and bio-fouling.

Warranty: 1-Year Official VFD Replacement Warranty

Power supply: Industrial pumps and RO plants need a 3-phase 380/415 V, 50 Hz supply. Light valves and dosing pumps run on 220 V single phase.
Membranes and CIP: Membranes typically last 2.5–4 years depending on feed SDI and TDS. A chemical clean-in-place every 3–6 months restores flow.
Backwash and media: Backwash every 2–7 days depending on turbidity. Replace sand, carbon and softening resin every 18–24 months.
Origin and documents: Brand, model, declared origin and available manufacturer documents are confirmed in the written quotation, with warranty stated per item.
