An antiscalant for feedwater with higher silica scaling potential combined with dispersant properties to inhibit colloidal fouling.

Effectively Controls:

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

Effective in retarding polymerization and precipitation of reactive and non-reactive silica.

Effectively controls inorganic scales over a large concentration range.

Efficacious for controlling aluminum, iron, and heavy metals.

Protects membrane surface from deposition of colloidal foulants

Liquid formulation is safe and easy to use.


In the useful dosage range of 1-15 ppm, control of a wide range of inorganic scales at up to 100 x saturation values 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.
