Effect of dual flocculant by unmodified manihot esculenta starch and aluminium sulphate on the removal of chemical oxygen demand optimized by response surface methodology by Rahmat, S., Othman, N, Ahmad, S. N., Asharuddin, S. M.

“…Besides the performance of COD removal increased, the dosage of the chemical coagulant was reduced by up to 64% at the optimum condition of 18 mg/L alum dosage, 307 mg/L starch dosage, pH 9, and 27 mins settling time. The analysis of variance (ANOVA) indicated that the quadratic model was significantly developed with a p-value < 0.05. …”
