Multimedia Filtration (MMF) is often used upstream of RO/NF to remove suspended solids that can cause plugging of membrane feed channels and damage the membrane surface. However, MMF media is only efficient at removing particles larger than 20 – 50 microns. AWC has developed a line of membrane compatible organic and inorganic coagulants that agglomerate smaller silts, clays and colloids into larger clusters that are more efficiently filterable. All polymers have been tested extensively to ensure safe use with RO/NF membranes even in case of slight overdosing.
AWC RO biocides have been specifically selected for use with RO/NF membranes. Our product line includes oxidizing and non-oxidizing biocides that are selected based on water quality and frequency of biological fouling.
Our high performance reverse osmosis (RO) antiscalant are effective at remarkably low dosages. The use of AWC antiscalants can eliminate the need for acid dosing, enable plants to operate at higher recoveries, and reduce cleaning frequencies. AWC has developed highly effective inhibitors that are unparalleled in the industry at controlling the most challenging scales. All AWC antiscalants are NSF approved for use in potable membrane systems.
