Due to their high selectivity, Reverse Osmosis (RO) and Nanofiltration (NF) systems will inevitably experience fouling. Impurities, such as scale, microorganisms and suspended solids will cause the membrane elements to foul, which will cause the performance of the system to drop (e.g. reduced permeate flow, reduced permeate quality). Proper maintenance and cleaning of RO and NF systems significantly extends membrane life and improves the performance of the membrane elements. Aqua Clear offers a full line of chemical products and services for complete care and proper maintenance of Reverse Osmosis and Nanofiltration systems.
