description and use

Hypersperse MDC704 is a highly effective liquid antiscalant/antifoulant developed to control scale precipitates and reduce particulate fouling within membrane separation systems. This highly effective liquid antiscalant/antifoulant is formulated specifically to be used with SoliSep MPT150 coagulant. It is imperative that the coagulants used are compatible with the antiscalant/antifoulant being injected as incompatible chemicals may cause membrane fouling.

application

For maximum effectiveness, Hypersperse MDC704 should be added prior to the static mixer or cartridge filter housing.

For potable applications the maximum dosage is 10 mg/L. Maximum dilution is 10% with RO permeate or DI water.

dosing

Typical dosage range is between 1 and 6 mg/L.

Important Note: Over and under-dosing may cause membrane fouling so please contact your local VEOLIA representative to define the optimal feed point and dosage rate.

Maximum Dilutions
