Vitec® 8200

Summary

Product Identification

• Product Name: Vitec® 8200
• Product Type: Antiscalant/Dispersant – Liquid
• Key Features: Proprietary antiscalant/dispersant, all polymer blend, does not contain phosphate or phosphonate, inhibits scale and disperses colloidal particles. Approved for drinking water by NSF International under NSF/ANSI Standard 60.

Performance

• Scale Inhibition: Powerful inhibitor against carbonate and sulfate scales.
  • CaCO₃: CCPP ≤ 900 (LSI ≤ 2.5)
  • CaSO₄: 4 x Ksp
  • BaSO₄: 105 x Ksp
  • SrSO₄: 60 x Ksp
  • CaF₂: 1000 x Ksp
  • SiO₂: 1 x Saturation
• Compatibility:
  • Compatible with cellulose acetate and polyamide membranes from major manufacturers.
  • Effective in a wide range of feedwater types and pH ranges.
• Mechanism: Crystal modification distorts inorganic salt crystal growth, reducing system fouling.
• Economy: Threshold scale inhibition at low dosage rates allows economical system operation.

Application

• Injection Point: Downstream of multimedia filters and upstream of cartridge filters.
• Usage: Can be injected neat or diluted.

Dosing Guidelines

• Typical Dosage: 2 to 5 ppm.
• Optimization: A site-specific dose can be determined using the Avista Advisor computer program.
• Caution: Over or underdosing may cause unnecessary membrane system fouling. Contact Avista customer service for customized instructions.

Dilution

• Preferred Method: Injected neat.
• Diluent Options (if required): Demineralized water, RO permeate water, or softened water.
• Strength Restrictions:
  • Solution strength should not be less than 1%.
  • DI quality water must be used for dilutions below 10%.
  • This protects the internal bacteriostat which inhibits bacterial growth.

Specifications

• Appearance: Colorless to light amber liquid
• pH (as supplied): 10.5 – 11.5
• Specific Gravity @ 20°C: 1.15 ± 0.05

Packaging Formats

• Americas: Pails (45 lbs), Drums (500 lbs), IBC’s (totes) (2500 lbs)
• EMEA: Drums (500 lbs), IBC’s (totes) (2500 lbs)
• Custom packaging and bulk tanker delivery available on request.
