Vitec 7000A

Vitec 7000A is a proprietary liquid antiscalant and dispersant designed to inhibit scale and disperse colloidal particles in reverse osmosis (RO) and nanofiltration (NF) membrane systems. This formulation is an especially effective calcium sulfate (CaSO4) scale inhibitor, allowing up to 7 times saturation. It can be applied at lower dose rates than Vitec 7000 where the carbonate scaling challenge is moderate. Vitec 7000A is compatible with organic coagulants and can be injected neat or diluted into a wide variety of feedwaters. Vitec 7000A is UK Drinking Water Inspectorate (DWI) approved.
