Reverse Osmosis

Protect the integrity of your membranes and decrease downtime due to cleaning

Membrane Biofouling Solutions

Biofouling can affect the operation of reverse osmosis membranes, requiring operators to temporarily stop water production operations to remove and clean the membranes. Not only is the down time costly, but the frequent cleaning can potentially lead to shorter membrane life. An effective membrane biofouling management program should include both contamination control and cleaning procedures to optimize operations and help ensure water reliability.

Our reverse osmosis antifouling microbiocides protect RO systems from microbiological fouling so they can supply the quantity and quality of water required.
