Accepta 2091 Antiscalant & Antifoulant for Reverse Osmosis, Nanofiltration & EDR Systems Antiscalant and antifoulant for reverse osmosis, nanofiltration and EDR membranes Accepta 2091 is a high performance, multi-functionalreverse osmosis antiscalant and antifoulant scientifically formulated for the treatment and protection of reverse osmosis (RO) membranes, nanofiltration (NF) and EDR membrane systems. Accepta 2091 can be used in the production of drinking water and in seawater desalination process applications and is highly effective in preventing the build-up of calcium carbonate scale on RO membrane surfaces. Besides its excellent calcium carbonate scale inhibition properties, Accepta 2091 is also effective at controlling calcium sulphate, calcium fluoride and metal oxides scale. Accepta 2091 can be used in the production of drinking water according to NSF standard 60. The maximum allowed dose rate is 10 mg/l. Product Benefits High performance RO membrane antiscalant and antifoulant Suitable for use in seawater desalination process applications Ideal for drinking water applications according to NSF standard 60 Highly effective calcium carbonate scale control Additional control of calcium sulphate, calcium fluoride and metal oxides scale Not affected by chlorine or other oxidizing biocides Product Properties Appearance: Liquid Colour: Clear, pale yellow Specific gravity: 1.22 @20 oC pH: 10.5 @25 oC Boiling point: > 100°C Flash point Non flammable aqueous solution Chemical reactivity Not affected by chlorine or other oxidising biocides *Full details of the product properties are available in the Safety Data Sheet. See below. Application & Dosage Information Accepta 2091 should be injected in membrane systems after chlorine and sodium metabisulphite treatment. Accepta 2091 can be used in the production of drinking water according to NSF standard 60 where the maximum allowed dosage rate is 10 mg/l. Accepta 2091 is not compatible with residual cationic polymers from the pre-treatment. The dosage level of Accepta 2091 is dependent on the quality of the feed water and the saturation indices of the various scales forming species present in the concentrated brine. Recommended injection point is into the feed water, downstream of any filtration equipment and cartridge filters. Accepta 2091 is miscible with water in all proportions. It may be applied as neat product, or as a solution in permeate water. A minimum dosing solution strength of 10% is recommended. This product should be dosed continuously and proportionally to the feed water flow. It is always advisable to carry out a 'Control Of Substances Hazardous to Health' (COSHH) assessment before use.
