In normal operation, the membrane sheet in reverse osmosis membrane elements can become fouled by suspended solids, microorganisms, and mineral scale. AM-22 Alkaline RO membrane cleaner is specifically formulated to clean biological growth (also known as organic fouling) from RO membranes.
Organic Fouling can be identified by the following symptoms:
- The RO Membrane will likely exhibit low permeate flow
- Salt rejection will usually be as good if not better than original test
- The membrane may have strong odor
- Possible mold growth on the membrane scroll end
Regular cleaning of the membrane elements minimizes the loss of performance and extends membrane life. Membrane elements should be cleaned whenever the normalized permeate water output rate drops by 10% from its initial flow rate (the flow rate established during the first 24 to 48 hours of operation), when salt passage in the product water increases over 5-10%, or when normalized pressure drop across the membrane increases by 10-15%.
AM-22-5 RO alkaline membrane cleaner is sold in powder form in a 1 gallon pail. Chemical mixing instructions, membrane cleaning instructions, product specifications, and SDS/MSDS sheets are included with each container. AM-22 is not considered DOT hazardous for shipping.
Applied Membranes, Inc. alkaline membrane cleaner is a result of over 35 years of hands-on experience of water quality engineers and chemists. WaterAnywhere offers technical expertise and assistance in troubleshooting and cleaning of RO membranes to give you an optimum system performance.
