Protecmbc551 Alkaline RO Cleaner for Seawater Desalination Remove Bio-Adhesive Organic Fouling

It targets oil, organics, bio-adhesive membranes and acid-insoluble substances including silicates and sulfates. For inorganic scales such as calcium carbonate and metal hydroxides, pair with ProtecMBC1550W acid cleaner. Combined cleaning is preferred for mixed fouling commonly seen in seawater desalination.

Standardized permeate flow drops by 10-15%; standardized feed-to-concentrate differential pressure rises by 10-15%; feed pressure increases by 10-15%; standardized desalination rate decreases by 1-2% or permeate salinity rises obviously. Chemical cleaning is suggested when any above-mentioned sign occurs.

Typically 1-2% (10-20 L per 1000 L water); adjust based on fouling severity and manufacturer guidelines

No, never mix acidic and alkaline cleaners directly; flush thoroughly between different cleaning steps

Add the cleaner slowly into cleaning tank with dilution ratio 1.5%-2.5%. Circulate by clean water pump for full mixing, adjust pH value of cleaning solution to 11.5-12.0. Never inject undiluted chemical directly into membrane housings.
