Regular chemical cleaning of RO membranes will help to increase its performance and will extend its useful life. The main concern with cleaning is that it should be done before the situation gets too bad as then the membrane may become fouled and will have to be replaced. Cleaning should be undertaken whenever the permeate flux differential pressure or conductivity changes to undesirable values. However it is better to clean the membrane regularly after a predetermined interval. Each type of fouling requires a different cleaning strategy depending on the water supply membrane fouling may be inorganic organic microbiological or a combination. Our NSF Certified WTROC1800 - FOOD GRADE RO MEMBRANE ALKALINE CLEANER are specially designed chemicals that keep these contaminants from attaching to the membrane surface. They also prove economical in the long run. Our Alkaline Cleaner is highly effective in removing deposits including colloids and organic biofoulants. It is a combination of Alkaline cleaner and a novel surfactant.
