Abstract
Our investigation is to study the effectiveness of chitosane as a coagulant aid to a synthetic coagulant sulfate of aluminiumin the treatability of surface waters. Waters of two dams (Keddara and Beniamrane) were studied, they differ mainly by turbidity. The performance of the method of coagulation-floculation and the quality of treated water was evaluated by measuring the residual turbidity, absorbance UV254nm and the residual aluminum in water. The results show a significant divergence in the effectiveness of chitosan on different water loaded with a better removal for the more turbid water. The residual aluminum levels after optimization of operating conditions did not exceed acceptable level of 0.02 mg/l. Hence, chitosan could be used as natural coagulant aid for drinking water treatment. With its non-toxicitythe chitosan can be the best substitute to conventional synthetic polyelectrolyte used so far.
