| Abstract: | In the paper, clarification process of wastewatcr of alcohol production from sugarcane juice was investigated by using chitosan-FeCl3 as composite flocculant. Effect of process conditions such as flocculant dosage, pH, temperatureand stirring time on clarification effect of wastcwater were evaluated. The results showed that chitosan-FeCl3; was an excellent composite fIocculant for clarification of this kind of wastewater. 60 % COD removal efficiency could be achieved in optimal flocculation conditions. And the experimental results would serve as technologic basis for treatment of wastewater of alcohol production from sugarcane juice. |
