Qemi polymer dilution, preparation and activation guidelines and equipment

To achieve maximum effect from a polymer, it must be prepared properly before being added to the treatment point. This applies to all polymer applications, from drinking water clarification to industrial oily waste water treatment to sludge dewatering.

Following are the suggested dilution guidelines:

POLYMER

DILUTION STRENGTH

DILUTION TIME

LIQUID COAGULANTS (polyamines, blends polyDADMACs, M.F.)

5-10%

IMMEDIATE

SOLUTION FLOCCULANTS (MANNICHs, copolymers)

10-20%

2-3 MIN.

EMULSION FLOCCULANTS

0.1-0.5-1.0%

30 MIN. +

POWDER FLOCCULANTS

0.05-0.5%

1 HR. +
