Genesys MP


Genesys MP is a broad spectrum liquid antiscalant, approved for use in large municipal Reverse Osmosis and Nanofiltration systems.

It is effective in brackish and sea-water applications preventing inorganic scale, particularly calcium carbonate, iron and silica thus reducing the frequency of membrane replacement and cleaning.

Genesys MP is effective at a Langelier Saturation Index (LSI) of +2.3 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.


Genesys MP should be dosed continuously to the feed water upstream of the cartridge filters. Typical dosage rates are 1 – 5 mg/L.

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

The optimum dosage rate can be calculated using the Genesys Membrane Master software. Genesys MP can be diluted and is fully miscible with water in all proportions.

Health and Safety

Genesys MP is an aqueous solution of neutralised phosphonic acid and does not contribute to assimilable organic carbon (AOC), which can act as a source of nutrient for micro-organisms. Genesys MP 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.
