Hypersperse MDC220 is a highly effective liquid Antiscalant/Antifoulant developed to control scale precipitates and reduce particulate fouling within membrane separation systems. Use of this product provides longer run times and extended element life resulting in reduced operating and capital costs. Years of use  in industrial applications show excellent results in membrane separation process including reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) applications.


Hypersperse MDC220 is a liquid material, available in a wide variety of customized containers and delivery methods. Contact your Betz Dearborn sales representative for details.


For maximum effectiveness, Hypersperse MDC220 should be added prior to the static mixer or cartridge filter housing For portable application, the maximum dosage is 10 mg/L. Maximum dilution is 10% with RO permeate or DI water

Typical dosage range is between 2 and 6 mg/L

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

VITEC 5300


Avista Technologies meet the specialized needs of the membrane separation industry worldwide, supplying chemicals and technical services to keep plants running efficiently. Their focus is entirely on membrane system chemistry & support.


We are pleased to offer now ex-stock their RO Antiscalant Vitec 5300 a highly effective threshold scale inhibitor. Low application rates of Vitec5300 are required to keep large amounts of scale in solution.


Vitec 5300 is primarily used to control scale precipitates & reduce inorganic & colloidal fouling in spiral & hollow fine fibre membranes.


Other features of Vitec 5300 are as under:

         Highly effective antiscalant across a wide quality of feed water.

         Compatible with all membrane types.

         Effective over a wide pH range.

         Crystal modification distorts inorganic salt crystal growth reduces system fouling.

         Compatible with poly electrolytes.

         Achieving threshold scale inhibition at low dosage rates offering excellent economical running costs.


The most efficient dose rate is dependent on a number of factors, including feed water quality, system operating recovery & membrane chemistry. Please advise us your RO Plant data & feed water analysis for our accurate dosing recommendations.
