Vitec® 5000
Antiscalant
Data Sheet
Vitec® 5000 is a liquid antiscalant/dispersant blended to inhibit scale and disperse colloidal particles in cellulose acetate and thinfilm membrane separation systems. The formulation has been certified by the National Sanitation Foundation (NSF) under ANSI/NSF Standard 60 for use in producing potable water. In addition UK drinking water approval has been granted.
This formulation is its compatible with Avista Technologies organic coagulants.
Performance:
Vitec® 5000 antiscalant offers a variety of performance and application benefits:
- Powerful inhibitor against a variety of carbonate and sulfate scales:
| CaCO3 | CCPP > 900
(LSI >2.8) |
| CaSO4 | 3.0 x Ksp |
| BaSO4 | 105 x Ksp |
| SrSO4 | 20 x Ksp |
| CaF | 1000 x Ksp |
| SiO2 | 120 ppm |
- Highly effective at low dose rates in a wide range of feedwater types and pH ranges.
- Compatible with polyelectrolyes.
- Provides both scale and inorganic fouling control.
- Compatible with all membrane types.
Application:
Optimum Vitec® 5000 performance is achieved when the chemical is injected upstream of the membrane system and where possible of cartridge filters.
Dosing Guidelines:
The typical dosage range is between 2 to 5 ppm. A site-specific dose can be determined using the
Avista Advisor computer program. Like any injected chemical, over or underdosing may cause unnecessary membrane system fouling. Please contact the Avista customer service department for customized dosing instructions.
Dilution:
If dilution is required, Vitec® 5000 should be diluted with demineralized water or RO permeate. If neither of these water sources is available, softened water may be substituted. The dilution for Vitec® 5000 should not exceed 10% by weight.
