This document contains two graphs showing the effect of different concentrations of Curiflok flocculant and PAC coagulant on the reduction of total solids in water. The first graph shows that using Curiflok at concentrations between 2-10 mg/L reduced total solids by 40-90%. The second graph shows that using PAC at concentrations between 0.4-0.8 g/L reduced total solids by 30-80%.
