description and use

Hypersperse MDC704i is a highly effective and safe 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. The product has shown excellent results in membrane separation processes including RO, NF and EDR.

application

For maximum effectiveness, Hypersperse MDC704i should be added upstream of the static mixer or cartridge filter housing.

dosing

Typical dosage range is between 1.5 and 5 mg/L. For potable applications, the maximum dosage is 12 mg/L.

To determine the adequate dose rate for a certain system it is recommended to use the new Argo Analyzer 4.1 simulation software. It will provide the best application dosage linked to the specific water chemistry and system design.

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

Dilution Guidelines: On-site dilution of Hypersperse MDC70i4 is possible; however, product dilution to concentrations below 20% is generally not recommended. When diluting, use high quality water such as permeate or deionized water. When feeding diluted product, examine the make-down tank for evidence of microbiological (MB) growth. If MB growth is observed, sanitize the tank and reduce the batch size. For best results, Hypersperse MDC704i should be fed neat.

Maximum Dilutions

Maximum dilution is temperature related as shown below.

Temperature Maximum Dilution, %

<30°C (86°F) 20

30-35°C (86-95°F) 35

>35°C (95°F) 70
