Products AWC® provides customized solutions for membrane cleaning, based on your feedwater chemistry, your operating restrictions and your treatment goals. Our aim is to ensure that your membrane system operates at maximum productivity without impacting your desired water quality. Reverse Osmosis & Nanofiltration Reverse Osmosis & Nanofiltration are now being used in a broad range of applications including potable water, mining, leachate, municipal and industrial reuse. AWC® has developed an extensive line of RO antiscalants, reverse osmosis membrane cleaning chemicals and biocides to control and reverse all scales and foulants that can form in these applications. Pretreatment 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. Learn More Reverse Osmosis (RO) Antiscalant 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 3/5


most challenging scales. All AWC antiscalants are NSF approved for use in potable membrane systems. Learn More RO Biocides 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. Learn More Dechlorination Chemicals AWC dechlorination chemicals have been specially formulated for long term shelf-life and are odor-free. In addition to neutralizing free and combined chlorine to protect RO/NF membranes, they also deactivate all other oxidizing and non-oxidizing biocides; this makes them essential tools for environmental discharge. Learn More RO Membrane Cleaning Chemicals AWC RO membrane cleaning chemicals are highly effective for removing even the most stubborn scales and foulant from RO/NF membranes. High pH and low pH chemicals are available in liquid and powder form. All AWC cleaning chemicals are NSF approved for use in potable membrane systems. Learn More Microfiltration/Ultrafiltration Chemicals MF/UF systems are widely used for treating surface and wastewater, and are sometimes applied as pretreatment for RO/NF systems. AWC has developed an extensive line of antiscalants and cleaning chemicals for use with MF/UF systems. Membrane Antiscalant MF/UF membranes do not reject salts, and scaling is therefore not a common occurrence. However, scaling can occur under certain conditions, especially in systems where air sparging is used frequently or high pH chemically enhanced backwashes (CEB) are applied. AWC has developed a line of membrane antiscalants that are approved for use in potable MF/UF systems. All AWC antiscalants are NSF approved for use in potable membrane systems. Learn More Cleaning Chemicals AWC MF/UF cleaning chemicals are proprietary formulations for extremely stubborn foulants. While aggressive commodity chemicals such as bleach and caustic soda are commonly used with PVDF and PES membranes, they are not always effective at removing organic foulants. AWC has created a full line of MF/UF cleaning chemicals to address the varying chemical tolerances of PVDF, PES, PAN, PP, and CA membranes. All AWC cleaning chemicals are NSF approved for use in potable membrane systems. 4/5
