Remove turbidity for wastewater. using natural coagulants such as Moringa oleifera. seed powder and mango seed powder

Abstract

Drinking water is essential for human consumption, but raw water consists of organic and inorganic matter, which is hazardous to health. Hence, it is necessary to remove these from water to make it potable. Water treatment has is carried out to remove these particles; generally, chemical coagulants treat turbid water. Water treatment usually trailed by coagulation-flocculation sedimentation; in flocculation, water continuously stirred after the addition of chemical coagulants, which leads to the formation of ‘flocs’ by the accumulation of microscopic particles present in it, to remove the flocs formed filtration and sedimentation is adopted. To carry out water treatment in developing countries, the use of coagulation, flocculation, and sedimentation is severe because of high initial cost, maintenance cost, and inadequacy of chemical coagulants such as alum, aluminium sulphate. Hence various natural coagulant with high efficiency is used in removing turbidity in domestic and industrial water, and this methodological brief gives the various applications of natural coagulant powders and alternative result instead of using chemical coagulants.
