AWC® ANTISCALANTS

AWC®’s powerful antiscalants for the mining industry enable Reverse Osmosis (RO) systems to operate at higher recoveries with cost-effective dosages, effectively preventing scaling and maintaining system efficiency and performance.

Product DescriptionBenefitsApplications
AWC®
A-102 Ultra
Broad spectrum scale inhibitor designed for use with municipal RO & NF membrane systems.Inhibits formation of calcium sulphate, calcium flouride, barium sulphate, strontium sulphate & silica. Stabilises metal ions to prevent metal oxide precipitation and disperse metal oxides/hydroxides silt and clay particles. Compatible with all major membrane manufacturers.Environmentally compatible, especially where discharge of waste into environment is a concern.
AWC®
A-110
RO antiscalant designed to inhibit silica and phosphate scale formation in membrane separation processes.Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.3. Inhibits calcium phosphate scale formation even in the presence of coagulant carryover carryover, disperses precipitated scales. Effectively stabilises metal ions and disperses insoluble metal oxides in the reject. Inhibits amorphous silica and silicate scale formation. Disperses colloidal silica.Controls calcium fluoride, calcium sulfate, barium sulfate and strontium sulfate scales in waters with a high fouling potential.
AWC®
A-119
Premium broad spectrum antiscalant designed to inhibit inorganic scale formation in membrane separation processes.Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.2.
Maintains good scale inhibition even in the presence of high levels of iron. Effectively disperses metal oxides, colloidal silica and other inorganic particulates such as silt and clays. Stabilises all metal ions to prevent metal hydroxide, metal phosphate, and metal silicate precipitation.
Designed for use with RO/NF feed water that contains high levels of iron in the ferric state (oxidized iron), aluminum, and a high potential for formation of amorphous silica and silicate scales. Controls calcium sulfate, barium sulfate, and strontium sulfate in waters with moderate scaling potential.
