To ensure continuous stirring of the samples, Phipps & Stirrer model 7790-400 with 10 rpm was used over the test period. The mixtures from the above experiments were filtered through a 0.45 μm filter paper, and acidified with a nitric acid solution to make pH <2 for the chemical analyses.

apparatus (Model 7790-400, Phipps & ) with 2 L cylindrical beakers was used for coagulation experiments. For coagulant dose determination various amounts of the coagulant were added into 1 L of the synthetic feed water. The rapid mixing was provided for 1 min at 200 rpm. Flocculation was done at 40 rpm for 20 min (Table I).
