Comparison of optimal dosages (OD) of coagulant/flocculants to treat one m3 of algal turbid water and corresponding algal turbidity removal efficiencies (TRE) using chitosan and Al sulphate (data from Dong et al. (2014))
| Coagulant/flocculant | Price (US $/kg) | Optimum dose (g coagulant/ m3 water) | Turbidity removal efficiency (%) | Cost (US $/m3 water) |
|---|---|---|---|---|
| Chitosan | 51.2 | 0.4 | 94.7 | 0.02 |
| Al2(SO4)3 | 5.8 | 20.0 | 89.2 | 0.12 |
