The document shows two line graphs comparing the concentration of different flocculants - Curiflok and PAC - to the percentage reduction of total solids. The Curiflok graph shows reduction of total solids from 2-10% with concentrations of Curiflok from 0.4 to 1 mg/L. The PAC graph shows reduction of total solids from 0.4 to 1 g/L of PAC.
