RO Membrane Cleaner - ROCclean 68 is a membrane cleaner specifically developed to remove iron fouling from reverse osmosis (RO) and nano-filtration (NF) membranes. It can also be used to remove light calcium carbonate deposition.

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.

The efficacy of ROCclean 68 is enhanced by the addition of ROCclean 66 to the cleaning solution; some minor pH correction may be necessary. ROCclean 68 should always be used as recommended by the membrane manufacturer with respect to pH, temperature, flow rate and differential pressure.
