The Patented RPI-4900 is specially designed to inhibit scale formation in SeaWater 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, Magnesium hydroxide, calcium sulphate and Iron/Manganese oxides. RPI-4900 also displays anti-oxydizing properties able to block most of SWRO metal catalytic oxidation reactions. It performs over a super broad pH range, ideal for second pass SWRO units.
