AWC A-120 – Calcium Phosphate Inhibitor
AWC A-120 Phosphate free Scale Inhibitor
Premium phosphate free antiscalant that exhibits excellent control of phosphate, sulphate at high saturations as well as control of carbonate and low levels of silica scales. Can disperse clays and silts to avoid colloidal silica fouling. High strength formulation ensures low dose requirements and maximal protection.
A clear light yellow to amber liquid, completely water soluble.

Safety and Handling
Store in cool, dry and well-ventilated area. Keep containers closed. Wash contaminated clothes before re-use. Wash thoroughly after handling. For more information, see the Safety Data Sheet provided with this product.
Chemical Feeding and Control
Injection:
AWC A-120 should be injected continuously into the RO feedwater line, always downstream of multimedia filters, and preferably downstream of the cartridge filters in the presence of a static mixer. In the absence of a static mixer, dosing upstream of the cartridge filters will serve as a substitute to improve mixing.
Dosing:
The dosage required to inhibit scale formation will typically be in the range of 1- 5 ppm, depending on feed water quality and system operating parameters. Dosage can be determined using Proton® membrane antiscalant projection software, or can be provided by an Membrane Works technical representative.
Dilution:
AWC A-120 is designed to be fed neat. However, if the minimum output of the dosing pump exceeds the required dosage, then dilution will be necessary. For product dilution, always use water that is free of any chlorine or detectable hardness – deionized water or RO permeate are preferred due to their higher purity, but softened water is also acceptable.
This product contains a preservative to prevent biological growth in the feed tank. Dilution in excess of 10X will impact the potency of the preservative. If dilution beyond 10X is unavoidable, it is recommended to replace the diluted product frequently, preferably every 7 – 10 days.
