Coagulation behaviors of CMHa versus PAC for paper-making wastewater treatment (original wastewater 850 NTU).
| Dosage of flocculants (mg/L) | CPAM (mg/L) | Settling time (s) | Residual turbidity (NTU) | Coagulation behaviors |
| SPAC (100) | 3 | 50 | 50 | Smaller alum floc | SPAC (120) | 3 | 40 | 42 | Larger alum floc | CMHa (50) | 3 | 50 | 65 | Larger alum floc | CMHa (100) | 3 | 40 | 52 | Larger alum floc |
| SPAC (200) | | 70 | 43 | Smaller alum floc | SPAC (250) | | 60 | 40 | Larger alum floc | CMHa (100) | | 60 | 45 | Larger alum floc | CMHa (150) | | 60 | 42 | Larger alum floc |
