The RPI-3000A is designed to inhibit the mineral scale formation inside Reverse Osmosis systems, particularly with difficult Brackish feed water. The RPI-3000A is highly effective against Calcium Sulphate, Calcium&Magnesium Carbonate and Calcium Fluoride scaling.

RPI-3000A has the Dual Strength to inhibit the crystal growth mechanism and to disperse the tiny oxide and micro-crystal particles.


RPI-3000A is approved for use with cellulose acetate and polyamide membranes. The required dosage level ranges from 1 – 10 ppm as delivered. The dosage is proportional to the feed water flow. RPI-3000A can be used in its commercial form or diluted with pure water in any ratio. A maximum dilution ration of 1 to 10 must be respected. Diluted preparations must be rapidly consumed, within 24 hours ideally. RPI-3000A is easy to use, safe to handle and safe to store for several months.
