Vitec 7000

Vitec 7000 is a multicomponent liquid antiscalant and dispersant that provides a high level of sulfate inhibition and allows increased reverse osmosis (RO) system recoveries in challenging waters. It prevents calcium sulfate (CaSO4) scale precipitation, allowing up to 6 times saturation. The primary application of this product is brackish water or wastewater rich in sulfate, which requires a specialty product for economic membrane system recovery. It is successful in industrial and potable applications. Vitec 7000 is approved by the NSF and the UK Drinking Water Inspectorate (DWI) and conforms to EN 15040 standards.
