AWC’s powerful antiscalants allow reverse osmosis (RO) system operation at higher recoveries while using cost effective dosages.
| Product | Description | Benefits | Applications |
|---|---|---|---|
| AWC A-102 Plus | Broad spectrum scale inhibitor designed for use with municipal RO & NF membrane systems. | Inhibits formation of calcium sulphate, calcium flouride, barium sulphate, strontium sulphate & silica. Stabilises metal ions to prevent metal oxide precipitation and disperse metal oxides/hydroxides silt and clay particles. Compatible with all major membrane manufacturers. | Environmentally compatible, especially where discharge of waste into environment is a concern. |
| AWC A-102 Ultra | Broad spectrum scale inhibitor designed for use with municipal RO & NF membrane systems. | Inhibits formation of calcium sulphate, calcium flouride, barium sulphate, strontium sulphate & silica. Stabilises metal ions to prevent metal oxide precipitation and disperse metal oxides/hydroxides silt and clay particles. Compatible with all major membrane manufacturers. | Environmentally compatible, especially where discharge of waste into environment is a concern. |
| AWC A-108 | Premium broad spectrum antiscalant designed to inhibit inorganic scale formation in membrane separation processes. | Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.3. Maintains good scale inhibition even in the presence of moderate levels of iron. Also exhibits control of silicate and phosphate scales at moderate to high levels. Effectively stabilises metal ions and disperses metal oxides and other inorganic particulates such as silt and clay. | Controls calcium sulfate, barium sulfate and strontium sulfate scales in waters with an extremely high scaling potential. |
| AWC A-110 | RO antiscalant designed to inhibit silica and phosphate scale formation in membrane separation processes. | Inhibits calcium carbonate scale up to a Calcium Carbonate Nucleation Index (CCNI) of 2.3. Inhibits calcium phosphate scale formation even in the presence of coagulant carryover carryover, disperses precipitated scales. Effectively stabilises metal ions and disperses insoluble metal oxides in the reject. Inhibits amorphous silica and silicate scale formation. Disperses colloidal silica. | Controls calcium fluoride, calcium sulfate, barium sulfate and strontium sulfate scales in waters with a high fouling potential. |
| AWC A-119 | Premium broad spectrum antiscalant 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. Maintains good scale inhibition even in the presence of high levels of iron. 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. | Designed for use with RO/NF feed water that contains high levels of iron in the ferric state (oxidized iron), aluminum, and a high potential for formation of amorphous silica and silicate scales. Controls calcium sulfate, barium sulfate, and strontium sulfate in waters with moderate scaling potential. |
Product and customer insights
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
