Sewage Water

Treatment

Used for acidophilic water systems. If matched with PAC, aluminum sulphate,

the effect will be excellent.

3

Industrial

Wastewater

Treatment

Dosing polyacrylamide can reduce the consumption of coagulant and speed up

sedimentation. Water purification chemicals, industrial wastewater treatment, sewage water treatment

4

Coal Mine

Washing

Coal washing tailing centrifugal separation
Sedimentation and filtration of coal powder and coal mud.
Highly improve the recovery rate of coal powder and the filtration speed.

5

Paper-making

Used as fixing agent, residency agent, filtration aid and paper dry and wet

intensity reinforcing agent in paper-making industry.

Sugar and

juice mills

For sugar and juice flocculation, sedimentation, clarification and floatation

7

Textile

Textile Sizing, as a kind of composition for chemical grout, starch textiles

Highly improve the adhesive property, penetrability and desizing performance, enable the textile to have electrostatic prevention performance, reduces the desizing rate, and reduces the starch mixing spots, cloth machine breaking efficiency, and falling objects.

1

Dissolving

concentration:

Polyacrylamdie (polyelectrolyte/flocculant) should be standardly be dissolved to 0.1-0.5% concentration.

2

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 lower than 1 hour of agitation to completely dissolve the powder. Incomplete mixture of flocculant or lumping may inhibit the performance of the flocculant.

3

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.

4

Application

and Dosage:

The dosage range of varies from 1 - 3.0 ppm depending upon the type of effluent and application. Advised to do jar tests for evaluating the functioning and approximate dosage.

5

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 flocs properly at this time and note the sedimentation and clarity of top solution.
