Chitosan based grey wastewater treatment—A statistical design approach
2014
Thirugnanasambandham, K. | Sivakumar, V. | Prakash Maran, J. | Kandasamy, S.
In this present study, grey wastewater was treated under different operating conditions such as agitation time (1–3min), pH (2.5–5.5), chitosan dose (0.3–0.6g/l) and settling time (10–20min) using response surface methodology (RSM). Four factors with three levels Box–Behnken response surface design (BBD) were employed to optimize and investigate the effect of process variables on the responses such as turbidity, BOD and COD removal. The results were analyzed by Pareto analysis of variance (ANOVA) and second order polynomial models were developed in order to predict the responses. Under the optimum conditions, experimental values such as turbidity (96%), BOD (91%) and COD (73%) removals are closely agreed with predicted values.
