RO Membrane Cleaner - ROCclean 67 has been developed for the cleaning of reverse osmosis (RO), nano-filtration (NF) and ultra-filtration (UF) membranes. Its formulation is based on an anionic surfactant and is most effective in removing colloidal and other organic matter. 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.

When ROCclean 67 is used in conjunction with microbial control agents such as our ROCbio range of products, it is effective against biofilm.

ROCclean 67 should always be used as recommended by the membrane manufacturer with respect to pH, temperature, flow rate and differential pressure.
