description and use

Hypersperse AF150 was developed to control scale precipitates and reduce particulate fouling within the membrane separation systems. This highly effective liquid antiscalant/antfoulant is formulated specifically to be used with theFiltermate C150 or C170 coagulants. It is imperative that the coagulants used are compatible with the antiscalant/antifoulant being injected as incompatible chemicalsmaycausemembranefouling.

typical applications

For maximum effectiveness, Hypersperse AF150 should be added prior to the static mixer or cartridge filter housing.

Dilution with RO permeate or DI water is recommended.

treatment and feeding requirements

Typical dosage range is between 2 and 6 ppm. A sample dosage calculation for general purposes would be as follows:

Water Technologies & Solutions fact sheet

Example: Hypersperse AF150 dosage was deter- mined to be 4.0 ppm. If the system feed flow is 100 m3/day, at what rate must the chemical be applied?

(Feed flow m3/day)/1000 x (ppm Hypersperse)

= kg per day

Kg per day/Specific Gravity

= Litres per day of Hypersperse

Calculation:

(100/1000) x 4.0 = 0.4 kg per day

0.4/1.1 = 0.37 litres per day

Important note: Over and under-dosing may cause membrane fouling so please contact VEOLIA. Our technical service engineers are available to provide custom dosagesforyourapplication.

packaging information

This product is available in standard sizes. Precautions should be taken to prevent the liquid from freezing as it may separate. Product integrity may be restored by slowly warming and then agitating.
