Abstract: Normally, industries and municipalities discharge the wastewater into open land or in water bodies without ample treatment due to which the ecosystem gets disturbed. For the treatment of wastewater, chemical coagulation is intended primarily to remove color, turbidity and chemical oxygen demand (COD) of the wastewater. For increasing the efficiency of primary treatment of industrial and municipal wastewater, better and more effective coagulants are necessary. This paper includes review of comparative studies of various coagulants such as Aluminum Chloro-Hydrate (ACH), Magnesium chloride (MgCl2), Poly-Glu, Poly-Aluminium Chloride (PACl) on laboratory scale, which can prove to be effective in enhancing the coagulation thus rendering primary treatment process of wastewaters more effective
