Description
Solution Making Method
| Dissolving concentration | Polyacrylamdie (polyelectrolyte/flocculant) should be standardly be dissolved to 0.1-0.5% concentration. |
| 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. |
| 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. |
| 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. |
