Safety and Handling

Store in a cool, dry place. In accordance with good safety practice, handle with care and avoid contact with eyes and prolonged or repeated contact with skin. For more information, see the Safety Data Sheet provided with this product.

Chemical Feed and Control

Injection:

Pureflux® GA 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 AWC technical representative.

Dilution:

Pureflux® GA must be dissolved prior to use. For product preparation, 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. To prepare, dissolve 2 lbs of Pureflux® GA in 1 gallon of water (or 240 grams in 1 liter of water).

This product contains a preservative to prevent biological growth in the feed tank. Dilution in excess of recommendation will impact the potency of the preservative. If dilution beyond recommendation is unavoidable, it is recommended to replace the diluted product frequently, preferably every 7 – 10 days.
