Contemplations and investigations on green coagulants in treatment of surface water: a critical review

Abstract Coagulation is an essential and easy process to treat water wastewater also adopt for point of use solutions. Coagulants have played a significant role in providing safe potable water. Nevertheless, the ill effects chemical coagulants, such as health substantial sludge quantities, cannot be ignored. Under given conditions, search alternative coagulants has been need hour, researchers presented those natural are promising alternatives. The exploration evaluation plant-based shown that these fit substitute sustainably. Previous studies efficacy various but could not fill gap existing terms cumulative database coagulants. In lines, focus current review present history science involved carried out evaluate them at different levels. Furthermore, 57 with their removing impurities from raw presented.
