Ropur AntiScalant

RPI - Antiscalants For application in Reverse Osmosis Systems

ROPUR RPI® Antiscalants are a set of products designed to operate reverse osmosis systems safely and at maximum efficiency.

ROPUR RPI® Antiscalants are used throughout Europe, the Middle East, Americas and APAC regions in hundreds of reverse osmosis systems, among which are many large drinking-water plants.

ROPUR RPI® Antiscalants products meet today's water treatment requirements, including NSF and KIWA as well as some country-specific drinking-water certifications.

ROPUR RPI® Antiscalants are compatible with RO membranes available on the market.

Environmentally friendly product line

RPI-2000	RPI-2000 is designed to inhibit scale formation in RO systems (equipped with polyamide, celluloseacetate and polyether membranes with an anionically charged surface). RPI-2000 is phosphorous free. RPI-2000 is designed for water with significant amounts of sulphate salts of calcium, strontium and barium as well as calcium carbonate. RPI-2000 also efficiently disperses fine water particles like heavy metal oxides.

RPI-2800	RPI-2800 is designed to inhibit carbonate and sulphate scale formation in RO systems equipped with polyamide, celluloseacetate and polyether membranes with an anionically charged surface. RPI-2800 is free of phosphorous compounds. RPI-2800 reduces organic fouling on membrane surfaces.

RPI-3000A	RPI-3000A is specially designed to inhibit scale formation in RO systems (polyamide, celluloseacetate and polyether membranes with an anionically charged surface). RPI-3000A has high cation dispersing properties. RPI-3000A is an excellent crystal growth inhibitor for calcium sulphate, calcium carbonate and calcium fluoride. A further advantage is the superior stabilization of iron oxide suspension in water in addition to the inhibition of the oxidation properties of salts like manganese (IV) oxide.
RPI-3000B

RPI-4000A	RPI-4000A is specially designed to inhibit scale formation in RO systems (equipped with polyamide, celluloseacetate and polyether membranes with an anionically charged surface). RPI-4000A has strong crystal growth threshold properties. RPI-4000A specifically inhibit calcium, barium and strontium salt scale formation. RPI-4000A is recommended for barium sulphate and strontium sulphate scaling issues. RPI-4000A also complexes transition metal cations like iron, manganese, copper and aluminium.

RPI-4500A	RPI-4500A is specially designed to inhibit the scale formation in RO systems (equipped with polyamide-, celluloseacetate- and polyether membranes with an anionically charged surface). RPI-4500A was specifically formulated to target calcium, strontium and barium sulphate salts. RPI-4500A also efficiently prevents the formation of calcium carbonate and silicate based scale.

RPI-4900	RPI-4900 is specially designed to inhibit scale formation in RO systems (equipped with polyamide, celluloseacetate and polyether membranes with an anionically charged surface). RPI-4900 shows a strong threshold effect and therefore prevents scaling of calcium carbonate, calcium sulphate and calcium fluoride in membrane systems. RPI-4900 aöso prevents deposits of iron salts due to its specific sequestrant property.

RPI-5000A	RPI-5000A is specially designed to inhibit SiO₂ scale formation in RO systems with polyamide, cellulose acetate and polyether membranes with a negative or neutral charged surface. RPI-5000A is a blend of polymers suitable for use within broad pH ranges. RPI-5000A is the most effective solution to prevent deposits of colloidal and dissolved SiO2 on the membrane surface. The maximal silicate concentration achievable in the RO-concentrate stream is between 260 and 300 mg/l.

RPI-6000	RPI-6000 is specially designed to inhibit scale formation in RO systems (equipped with polyamide, celluloseacetate and polyether membranes with an anionically charged surface). RPI-6000 is designed for water with an extremely high sulphate content (up to 15,000 mg/l). RPI-6000 also prevents calcium carbonate scaling. RPI-6000 is also recommended for the prevention of metal oxide deposits (iron oxide, manganese oxide).

RPI-7000A	RPI-7000 is specially designed for waters with high phosphate and silicate content. The product effectively prevents metal oxide deposit formation through sequestration. RPI-7000 is recommended for use with negative or neutral surface-charged polyamide, cellulose acetate and polyether membranes. RPI-7000 is compatible with RO membrane surfaces.
