AWC A-119 Iron and aluminium Inhibitor
Iron and Aluminium Inhibitor
Premium antiscalant designed to inhibit iron, aluminium, and silica scales especially in colloidal form. The product continues working even in the presence of iron that would deactivate other scale inhibitors. In addition, the product prevents deposition of already precipitated particles in the membrane system. Highly effective for control of aluminium silicate scales.Â
A colourless to light yellow liquid, completely water soluble.

Advantages
- Premium broad spectrum antiscalant designed to inhibit inorganic scale formation in membrane separation processes
- Designed for use with RO/NF feed water that contains high levels of iron in the ferric state (oxidized iron), aluminium, and a high potential for formation of amorphous silica and silicate scales
- Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.2
- Maintains good scale inhibition even in the presence of high levels of iron
- Controls calcium sulphate, barium sulphate, and strontium sulphate in waters with moderate scaling potential
- Effectively disperses metal oxides, colloidal silica and other inorganic particulates such as silt and clays
- Stabilises all metal ions to prevent metal hydroxide, metal phosphate, and metal silicate precipitation
- Environmentally compatible and fully biodegradable
- Certified by NSF to NSF/ANSI/CAN 60.
Packaging
- 20L pails
- 200L non-returnable plastic drums
- 1000L IBC
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 Feeding and Control
Injection:
AWC A-119 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 should be determined by modelling using AWC Proton® membrane antiscalant projection software.
