RPI-7000 is specially designed for waters containing phosphate and silicate salts. The 7000 reference effectively prevents the Phosphate Scale and Metal Oxide deposit formation, while exhibiting a bacteriostatic effect, making of the RPI-7000 the ideal Antiscalant for Water-Reuse application.

RPI-7000 is recommended for use with RO polyamide, cellulose acetate and polyether membranes.


RPI-7000 is liquid and should be dosed into the RO feed stream in as concentrated a form as possible. The required dosage level depends on the operating conditions and water composition and varies in the range of 1 to 10 ppm as delivered. RPI-7000 is easy to handle and does not contain any aggressive components. It is recommended to inject RPI-7000 undiluted.
