Comparison of efficiency of bioflocculant and chemical flocculants.
| Flocculant | Dosage (mg/mL) | Flocculating activity (%) |
|---|---|---|
| Bioflocculant | 0.2 | 94.88 ± 0.24a |
| Polyethylimine | 0.3 | 86.95 ± 0.28b |
| Alum | 0.8 | 77.13 ± 2.40c |
| Polyacrylamide | 0.1 | 95.02 ± 0.21a |
| Ferric chloride | 1.0 | 41.89 ± 0.10d |
Percentage flocculating activities with different alphabetic letters are significantly different (p < 0.05).
