Summary
Product identification
Scale Inhibitor ROPUR RPI-7000
GENERAL
RPI-7000 is designed for stabilization of waters with high phosphate content and is effective against silicate scales. It prevents the deposition of metal oxides through sequestration. The product is suitable for use in negative or neutral surface charged polyamide, cellulose acetate, and polyether membranes, with no interaction with the membrane material. RPI-7000 is a multifunctional copolymer with a polyacrylic acid backbone, suitable for use within broad pH ranges. It does not contain phosphonates or phosphates.
APPLICATION AND DOSAGE
RPI-7000 is a liquid that should be dosed as concentrated as possible into the RO feed stream. The required dosage level depends on operating conditions and water compositions, varying from 1 to 10 ppm as delivered. The product is easy to handle and does not contain aggressive components. Its pH value is slightly acidic.
Dosage is controlled proportionally to the feed water flow using standard metering pumps. Recommended fitting materials are PE, PP, or coated steel. Injection can be undiluted or as a solution up to 10%. If dilution is required, use only permeate or softened water. Diluted solutions must be consumed within 48 hours after preparation.
