It is a highly effective antiscalant, designed to inhibit inorganic scale formation in membrane separation processes. Inhibits crystal formation and growth of calcium sulfate, magnesium sulfate, barium sulfate and strontium sulfate scales under severe scaling conditions It is effective over a wide range of concentrations, and does not flocculate dissolved polymers such as residual coagulants or iron or aluminum-rich silica. Use of this product is recommended for reducing the operating and capital costs of reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) systems. Environmentally compatible, especially where discharge of waste into the environment is a concern Membrane Antiscalant. High CaSO4, BaSO4, SrSO4 Saturation ADVANTAGES. Moderate inhibition of carbonate, phosphate and silicate scale formation Stabilizes low levels of metal ions to prevent fouling of the membrane
