IWE AC3 Broad Spectrum Antiscalant and Antifoulant

 

[su_note note_color=”#e5f2ff” radius=”10″]IWE AC3 is a general purpose liquid antiscalant & antifoulant for use in Reverse Osmosis and Nano-filtration systems. This concentrated phosphonate product is effective against a wide range of inorganic scaling species and also sequesters trivalent metal cations such as iron, manganese and aluminium thus reducing the frequency of membrane replacement and cleaning.

IWE AC3 has proven to be effective at a Langelier Saturation Index (LSI) of +2.6 which means that systems can be designed and operated at their optimum recovery rates.

By reducing the amount of feed water used and concentrate to be discharged, significant savings can be made to both capital and operational costs.

Application

IWE AC3 should be dosed continuously to the feed water upstream of the cartridge filters. Typical dosage rates are 2 – 4 mg/L.

IWE AC3 may also be used in sea water applications where iron is present, recycle of brine is in use or there is no feed water pH reduction by acid dosing.

Typical dose rates are 0.5 – 1.0 mg/L

Under NSF listing the IWE AC3 dose rate in the feed water should be less than 5 mg/L in potable water systems.

IWE AC3 can be diluted and is fully miscible with water in all proportions.

Health and Safety

IWE AC3 is an aqueous solution of neutralised phosphonic acid. It has been approved for use in potable water applications and does not contribute to assimilable organic carbon (AOC), which can act as source of nutrient for micro-organisms. IWE AC3 is compatible with carbon steel and other commonly used materials of construction. Observe all safety precautions shown in the material safety data sheet, available on request.
