A more cost effective broad spectrum antiscalant for use with RO systems treating water with less scaling potential.

Effectively Controls:

Compatible with RO, NF, and UF membranes from all major manufacturers.

Controls inorganic scale over a large concentration range.

Decreases precipitation of aluminum, iron, and heavy metal salts

Liquid formulation is convenient and easy to use.


In the dosage range of 1 –15 mg/L (neat), control 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.
