In this study, the performance of a new bio coagulant (the carob) and a bio flocculent (cactus) was investigated for methylene blue dye and chemical oxygen demand removal from aqueous solution. For this purpose, response surface methodology (RSM) was applied to optimize four operating variables of coagulation/flocculation process which are: coagulant dosage, flocculent dose, initial pH and initial dye concentration. The results showed that the decrease of coagulant dose was always beneficial for enhancing dye removal. The optimum carob dosage, cactus dosage, initial pH and initial dye concentration were found to be 830mg/L, 64mg/L, 2 and 40mg/L, respectively. Dye removal of 94.63% and COD reduction of 74.12% were observed and confirm close to RSM results. It can be concluded that using the carob as a low-cost material in the coagulation/flocculation process for dye and COD elimination can offer some advantages such as high treatment efficiency and economic savings on overall treatment plant operation costs.
