Abstract

In this study, the coagulation using poly aluminium chloride (PAC) was applied in order to remove Basic Red 46, a cation dye from wastewater. The effects of some key operating parameters such as PAC dose, pH as well as contact time on the COD and color removal were investigated. Response surface methodology (RSM) showed that PAC dose of 785 mg/L; pH of 12; contact time of 105 minutes were optimum conditions for the coagulation of BR46.
