1

Flocculation Mechanism:

Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging and make flocculation structure enlarge and thicken, and have the functions of surface adsorption and electric neutralization.

2

Reinforcing Mechanism:

PAM molecule chain and dispersed phase form bridging bonds, ion bonds, and covalent bonds to increase combination strength.

1

Dissolving 

concentration:

Polyacrylamide (polyelectrolyte/flocculant) should be standardly 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 around 1 hour of agitation to completely dissolve the powder. An incomplete mixture of flocculants 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 varies from 1 - 3.0 ppm depending upon the type of effluent and application. You are advised to do jar tests for evaluating the functioning and approximate dosage.

5

Jar Test: 

Put a 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 the top solution.
