Abstract
The complex-­impurities-­based surface water potabilization comprises pre­ozonation at maximum 2g of O3/m3 for 2-­8 minutes, and coagulation with 10­-30 g/m3 of FeCl3 in the presence of 0.05-­0.1 g/m3 of anionic polyelectrolyte. Final ozonation at maximum 3g of O3/m3 for 4­-6 minutes is followed by adsorption on active carbon for 8-­10 minutes, and disinfection with 0.5­-2 g/m3 of chlorine.
