Industrial Reverse Osmosis S-100 Antiscalant

Industrial Reverse Osmosis S-100 AntiscalantAXEON S-100 Antiscalant is a highly effective antiscalant, specially formulated for feedwaters with high levels of metal oxides, silica and scale-forming minerals. It is effective over a wide range of concentrations, and does not flocculate dissolved polymers such as residual coagulants, 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. A special utility is in its application as a substitute for pretreatment with ion exchange beds.

Dosing Recommendations

AXEON S-100 Antiscalant should be injected into the feedstream prior to the static mixter and cartridge filter. Effective pH range is 5 - 10. If frozen, may be thawed and mixed before use. Stability is excellent, but best used within 12 months.

In the useful dosage range of 1 - 15 ppm, S-100 controls of a wide range of inorganic scales at up to 100 x saturation values or higher is possible. By monitoring the concentrate stream and trend charts, optimal dosage can be achieved for the control of scales including that from calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, iron hydroxide, aluminum hydroxide and silica.
