Wastewater Chemicals Cationic Polyacrylamide Powder With High Charge Degree

Papermaking Wastewater Chemicals Cationic Flocculant Polyacrylamide Powder

This is high molecular weight with high charge degree powder polyacryalmide / polyelectrolyte, used as flocculant in direct filtration process for settling of inorganic suspended solids, effluent water, and sludge dewatering. It is used for effluent treatment of inorganic suspended solids found in chemical, Fishery, food, textile, dye, other effluent water, mining and coal washing waste water, metal processing, etc.

Procedure and precautions upon dispersion and dissolving flocculants:
Dissolving time: The time required to dissolve the flocculant varies according to the type of flocculant, water quality, temperature and agitation. However, most flocculants generally require around 1 hour of agitation to completely dissolve the powder. Incomplete mixture of flocculant or lumping may inhibit the performance of the flocculant.

Agitation speed: The ideal revolution of the agitator is between 200-400rpm. A high speed agitator operating without reducing the revolution of a motor is not advised, since it may cut the molecules of the flocculant. An ideal agitator motor should be of 1HP for a 1-2m3 mixing tank.

Dissolving concentration: Flocculants should be standardly be dissolved to 0.1-0.2% concentration. It is also effective to start dissolving at a slightly higher concentration, and then dilute the flocculant mixture immediately before use.

Application and Dosage:
The dosage range of varies from 0.2 - 3.0 ppm depending upon the type of effluent and application. It is always advised to do a jar test for evaluating the functioning and approximate dosage.

Jar Test:

Put sample of effluent in a beaker and add it as designated, agitate for 1 minute at 100-120 rpm and then slowly agitate at 60rpm. Determine the floc properly at this time and note the sedimentation and clarity of top solution.
