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.VIEW ALL CHEMICALSVIEW SUPPORT SERVICES
Powerful against these and other types of scale:
Barium sulfate(BaSO4)Calcium sulfate(CaSO4)Strontium sulfate(SrSO4)Calcium carbonate(CaCO3)Calcium fluoride(CaF2)
- Formulated with a crystal modification property that distorts inorganic salt crystal growth to reduce system fouling.
- Compatible with polyamide membranes from all major manufacturers.
- Highly effective in a wide variety of feedwaters and pH ranges.
- 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.
