Reverse Osmosis Fresh water purification, food liquids processing, desalination or wastewater recovery, and industrial water purification processes are increasingly based on the use of reverse osmosis (RO) membranes. Such important investments necessitate meticulous care to prevent operational issues, including scaling and biofouling. Deposits on membranes can reduce permeate flow and increase pressure drop, significantly reducing permeate yield. Biofouling Prevention Biofouling can affect the operation of RO membranes requiring operators to temporarily stop water production 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 water reliability. Dow’s reverse osmosis antifouling microbiocides protect RO systems from microbiological fouling so they can supply the quantity and quality of water required. Scaling Prevention Feed water can be from different sources and contain different contaminants such as suspended solids and dissolved salts. Pretreatment focuses mainly on the removal of suspended solids while in RO systems salts can precipitate out due to supersaturation. Dow ACUMER™ portfolio for RO: |
