Reverse Osmosis Membrane Cleaner (Alkaline) - ROCclean 69 Print E-mail

Membrane Cleaner - ROCclean 69 is a liquid blend of dispersants and inorganic builders with an amphoteric surfactant. Specially developed as an alkaline cleaning formulation for removing organic debris and biofouling from RO and UF membranes, ROCclean 69 does not contain any amino carboxylic acid sequestrants.

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