About the mechanism of formation of iron hydroxide fouling layers on reverse osmosis membranes

Abstract The rate of fouling by deposition of iron hydroxide on tubular reverse osmosis membranes was studied under closely controlled experimental conditions resembling those of brackish water desalination. Feed brines of approximately 5,000 ppm NaCl were used to which small amounts of iron hydroxide were added. The effect of brine flow rate, product water flux, pH and oil contamination on the rate of fouling layer buildup was investigated. Results obtained suggested that the rate of membrane fouling due to iron hydroxide buildup is governed by two processes: nucleation and growth.
