RO Membrane Cleaner - ROCclean 66 is a good general-purpose reverse osmosis (RO) membrane cleaner designed to support the cleaning of acid insoluble sulphates of calcium, barium and strontium, as well as calcium fluoride. It is effective in removing iron oxides and hydroxides as well as calcium carbonate, though ROCclean 68 or hydrochloric acid are preferred for these scalants.

During normal operation, reverse osmosis and other membranes can become fouled, which greatly reduces the efficiency of the system. Deposits build up on the membrane until they cause a reduction in normalised permeate flow, increases in differential pressure and losses in salt rejection. The effects of fouling can lead to poor water quality, loss in production, unscheduled downtime and premature membrane replacement.

A regular maintenance and cleaning programme can provide a significant return on investment by extending system run time, preventing membrane degradation, maintaining lower feed pressures and extending the membrane’s life. ROCclean 66 is highly effective when used in combination with high pH detergent cleaners such as ROCclean 67 and ROCclean 69 to help remove organic substances and microbial slimes.
