dose, time and speed of coagulation were considered. Treated samples were analysed to determine the residual color and COD. Results: According to the results of our experiments, under optimum conditions of process (pH 9, doses of 250 mg/l coagulant and coagulation speed of 175 rpm with a duration of 5 minutes), the highest removal

For this purpose, response surface methodology (RSM) was applied to optimize four operating variables of coagulation/flocculation process which are: coagulant dosage, flocculent dose, initial pH and initial dye concentration. The results showed that the decrease of coagulant dose was always beneficial for enhancing dye removal.

Both coagulants efficiently removed the dye (about 85%) with a relatively low dosage (40 mg/l) in their optimum pH range. By adding kaolinite as a coagulant aid, the removal efficiencies tended to increase, especially for lower dosages of PAC and alum. With the increase of initial dye concentration, PAC and alum represented different behaviors.
