RO Membrane Cleaners & Reverse Osmosis Biocides
Regular chemical cleaning of RO membranes will ensure that they continue to perform and extend their useful life. The key thing with cleaning is to do it before the situation gets too bad because if you leave it too long the membrane may become irretrievably foul. Cleaning should be undertaken whenever the normalised permeate flux reduces by 10 – 15% or, either the normalised differential pressure or permeate conductivity increase by 10-15%. In many instances it is best to adopt a programme of regular preventive cleaning.
Depending on the characteristics of the water supply membrane fouling may be inorganic, organic, colloidal or microbiological in nature and often a combination. Each type of fouling requires a different cleaning strategy. 
AV-08is an alkaline reverse osmosis membrane cleaner for removing fouling caused by organic and colloidal foulants from RO and UF membranes.
AV-08 packages in 10kg buckets. 
AV-05is a mildly-acidic RO membrane cleaner for removing fouling caused by iron salts, oxides and hydroxides. It can also be used to remove light calcium carbonate scaling.
AV-05 packages in 10kg buckets. 
AV-13 is a cost effective RO biocide that can be used as an RO cleaner to remove biofouling or as a preservative to prevent microbial fouling developing when a reverse osmosis system is left off-line for an extended period.
AV-13 packages in 25kg buckets.
