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.VIEW ALL CHEMICALSVIEW SUPPORT SERVICES
Powerful against these and other types of scale:
Calcium carbonate(CaCO3)Calcium sulfate(CaSO4)Barium sulfate(BaSO4)Strontium sulfate(SrSO4)Calcium fluoride(CaF2)Silica(SiO2)
- Controls twice the level of sulfate saturation than broad spectrum products.
- Highly effective in a wide variety of feedwaters and pH ranges.
- Crystal modification property distorts inorganic salt crystal growth, reducing system fouling.
- Economical to use, offering threshold scale inhibition at low dose rates.
- Compatible with Avista™ coagulants.
Scaling means the deposition of particles on a membrane, causing it to plug.

Selecting the right cleaning chemicals extends system run times between cleanings, reduces chemical costs and extends productive membrane life and overall system up-time.
Provides a cost-effective solution for biological fouling, which is one of the most challenging issues faced by operators of polyamide membrane separation systems.
Inhibits scale while also dispersing colloidal particles. The inhibition and dispersant properties of Vitec products help extend system run times, reduce cleaning frequency, and increase the productive life of RO elements.
