AWC-A-101

Summary

Product Identification

• Product Name: AWC® A-101
• Product Type: Membrane Antiscalant
• Key Features: High CaSO₄, BaSO₄, SrSO₄ Saturation

Advantages

• Designed to inhibit inorganic scale formation in membrane separation processes.
• Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.2.
• Inhibits crystal formation and growth of calcium sulfate, barium sulfate, and strontium sulfate scales under severe scaling conditions.
• Provides moderate inhibition of carbonate, phosphate, and silicate scale formation.
• Stabilizes low levels of metal ions to prevent membrane fouling.
• Approved by all major membrane manufacturers.
• Environmentally compatible, especially where discharge of waste into the environment is a concern.
• Certified by NSF to NSF/ANSI Standard 60.

Typical Properties

• Appearance: Colorless to light yellow liquid
• Odor: Characteristic
• Solubility in water: Complete
• pH (as is) @ 25˚C: 3 - 5
• Specific Gravity: 1.20 ± 0.05

Chemical Feeding and Control

• Normally fed continuously prior to the final cartridge filter.
• Should be injected by a chemical dosing pump from a dilution tank or directly from the drum to the feed water line.
• The required dosage depends on feed water quality and membrane system size.
• An AWC technical representative will provide the approximate dosage rate for your system.

Safety & Handling

• Store in a cool, dry place.
• Handle with care, avoiding contact with eyes and prolonged or repeated skin contact, in accordance with good safety practice.
• Refer to the Safety Data Sheet for more information.
