Vitec® 4000

Summary

Product identification

Vitec® 4000 is a liquid antiscalant and dispersant.

Operating limits

• Inhibits silica scale precipitation at higher concentrations.
• Performs in reverse osmosis (RO) concentrate streams containing up to 4 mg/l of ferrous iron.

Feed water

• Suitable for high silica feedwaters.

Product water

• Approved for use in systems producing drinking water in the UK, conforming to DIN 15040.
• Certified by NSF International under NSF/ANSI Standard 60.

Instructions for use

Injection

• Inject downstream of multimedia filters and upstream of cartridge filters.

Dosing

• Typical dose ranges from 2-5 mg/l.
• Site-specific dose can be determined using the Avista Advisor software program.

Dilution

• Formulated to be injected neat.
• If dilution is required, use deionized water or RO permeate. Softened water may be substituted if deionized or RO permeate is unavailable.
• Dilution should not result in a solution strength of less than 10% to protect the internal bacteriostat.
