Table 15
Coagulation behaviors of CMHa versus PAC for coal-washing wastewater treatment (original wastewater 1200 NTU).
| Dosage of flocculants (mg/L) | CPAM (mg/L) | Settling time (s) | Residual turbidity (NTU) | Coagulation behaviors |
| SPAC (50) | 5 | 20 | 19 | Larger alum floc | CMHa (30) | 5 | 15 | 9.4 | Larger alum floc | CMHa (20) | 5 | 15 | 17 | Larger alum floc |
| SPAC (80) | | 150 | 40 | Smaller alum floc | CMHa (50) | | 60 | 14 | Larger alum floc | CMHa (40) | | 80 | 22 | Larger alum floc |
