Coagulation of reactive red 195 dye by using polyaluminium chloride as coagulant

This research aims to examine the efficiency of Polyaluminium Chloride (PAC) remove a reactive red 195 dye and find optimal condition coagulate this dye. In present investigation, effect pH (3-9) PAC dosages (500-5,000 mg/L) were studied 1,000 mg/L using jar test. The results showed that variations influenced PAC. With increase dosage, 500- 1,500 5,000 highest percentage colour removal in acidic pH, while 2,000 3,000 alkaline pH. was 99.47% at condition. These show is an effective coagulant RR195 coagulation process for dosage 9.
