Floc samples with different mixing ratios of clay and chemicals (flocculating agents)
| Clay suspension | Chemical solution | |||
|---|---|---|---|---|
| Dry clay: g | Deionised water: ml | Chemicals: g | Deionised water: ml | |
| Floc sample 1a | 40 | 1960 | 0.035 | 50 |
| Floc sample 2 | 80 | 1920 | 2.5 | 50 |
| Floc sample 3b | 80 | 1920 | 10 | 50 |
| Clay suspension | Chemical solution | |||
|---|---|---|---|---|
| Dry clay: g | Deionised water: ml | Chemicals: g | Deionised water: ml | |
| Floc sample 1 | 40 | 1960 | 0.035 | 50 |
| Floc sample 2 | 80 | 1920 | 2.5 | 50 |
| Floc sample 3 | 80 | 1920 | 10 | 50 |
Floc sample 1 is termed ‘slightly flocculated’
Floc sample 3 is termed ‘largely flocculated’
