The coagulation / flocculation process was used for the treatment of colour removal from textile wastewater with ferric chloride hexahydrate and ferrous chloride monohydrate. The process was very effective with 58 to 82% colour removal. The ferrous chloride monohydrate showed 58 to 64 % colour removal and ferric chloride hexahydrate showed 79 to 82 % colour removal. Reactive Indian dyes were used as model dyes in the textile dyeing wastewater. In order to determination the optimum pH and coagulat concentration, a series of jar tests was done. Some experiments were performed using round flocculation tank and the magnetic stirrer with high and slow speed mixing has an important role in the overall coagulation process efficiency.
