Application
Vitec™ 4000 is a liquid antiscalant and dispersant that offers excellent silica scale inhibition and allows increased system recoveries in high silica feedwaters. Vitec 4000 prevents silica scale up to 2.8 times saturation, without the addition of acid. It also prevents clay formation (aluminum silicates) in the second stage of systems as well as calcium phosphate. Vitec 4000 is effective in water containing high metals such as iron, aluminum, and manganese. It is highly successful in many different industries and applications including, but not limited to, mining, well water, high recovery applications, wastewater, and in regions with high volcanic silica.
Vitec 4000 is NSF approved.
Injecting
Best results are achieved when Vitec 4000 is injected downstream of multimedia filters and upstream of cartridge filters.
Dosing
A typical Vitec 4000 dose ranges from 2 to 5 mg/l. A site-specific dose can be determined using the Avista™ Advisor™Ci software program.
Dilution
Vitec 4000 is formulated to be injected neat. However, if dilution is required, use deionized water or reverse osmosis (RO) permeate. If neither of these is available, softened water may be substituted. The dilution for Vitec 4000 should not result in a solution strength of less than 10%. This guideline protects the effectiveness of the internal bacteriostat, which inhibits bacterial growth in the product packaging and feed tank.
