RPI-4000A
RPI-4000A is specially designed to inhibit the scale formation in RO systems operating difficult Brackish water. RPI-4000A displays a high crystal growth threshold value.
RPI-4000A is the ideal reference for water containing carbonate and sulfate salts and/or with high levels of Barium/Strontium salts and/or with high content of metal cations like Iron, Manganese, Copper, Aluminum…
Application
RPI-4000A 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-4000A can be used as it is or diluted with pure water in any ratio. Diluted preparations must be ideally used rapidly, within 48 hours after preparation. To avoid a storage tank biological fouling, it is recommended to clean from time to time the vessel with a biocide or with a 10% sodium bisulphite solution.
RPI-4000A is easy to use, safe to handle and safe to store for several months.
