The objectives of this study were to: select a method of evaluating these new compounds that would yield quantitative results in terms of parameters‐conventional standards of final water quality and particle sett1ing rate (this required the use of a settling column); determine the effect of polyelectrolytes in conjunction with ferric sulfate as the primary coagulant; determine the value of polyelectrolytes in reducing sedimentation time; and, determine the value of polyelectrolytes in reducing primary coagulant dose. The experimental approach used to evaluate the polyelectrolytes included a jar test apparatus and a settling column. Two parameters were chosen to measure the sample concentrations, turbidity and suspended solids. The equipment used was a commercial laboratory grade turbidimeter and a Jackson candle turbidimeter. It was necessary to use both turbidimeters owing to the large range in turbidity values. To determine suspended solids in the samples, a membrane filter was used.
