What is Turbidity Removal: FeCl3 vs. Alum Coagulants about?

The document compares the effectiveness of Fecl3 and alum coagulants for removing turbidity from water at different mixing speeds. It finds that at 60 rpm, adding 30g of Fecl3 increased turbidity more than the same amount of alum, but at 55 rpm alum increased turbidity more. The efficiencies of turbidity removal by alum were 52.5%, 60.5%, and 70% at 60, 55, and 45 rpm respectively, while efficiencies for Fecl3 were 56%, 69%, and 67.5% at the same speeds.
