Pretreatment of Reactive Dye from Textile Wastewater by Coagulation Technology

A physicochemical treatment was applied to study on removal of commercially used reactive dye and investigate the effectiveness of coagulation-flocculation from textile wastewater. Three types of coagulants were used like aluminium sulphate (alum), polyaluminium chloride (PAC), and magnesium chl...
