AWC A-103 Reverse Osmosis Membrane Antiscalant – Silica Antifoulant

Advantages AWC A-103 is a proprietary blend of antiscalants, antifoulants and silica dispersants. AWC A-103 is especially designed for use where silica levels are high, up to 250% saturation of Silica in the reject. AWC A-103 effectively disperses aluminum-silicate foulants such as Kaolinites. AWC A-103 stabilizes metal ions and disperses metal oxides such Iron and Manganese as well as colloidal particles such as silt and clay. AWC A-103 controls calcium carbonate, calcium sulfate, calcium phosphate, calcium fluoride, barium sulfate and strontium sulfate scales in waters with a high fouling potential. AWC A-103 has been approved by the National Sanitation Foundation (NSF) for the production of potable water in membrane separation processes. AWC A-103 is environmentally compatible, especially where discharge of waste into the environment is a concern.

In accordance with good safety practice, handle with care and avoid contact with eyes and prolonged or repeated contact with skin. For more information, see the Material Safety Data Sheet provided with this product.

Chemical Feeding and Control AWC A-103 is normally fed continuously prior to the final cartridge filter. It should be injected by chemical dosing pump from a dilution tank or directly from the drum to the feedwater line. The amount of AWC A-103 required to inhibit scale formation depends on the quality of feedwater and operational parameters of the membrane system. The appropriate dosage rate will be specified by the technical representative. Packaging AWC A-103 is packaged in 55 gallon, non-returnable plastic drums.
