INDUSTRIAL EFFLUENT TREATMENT BY MORINGA OLEIFERA AS NATURAL COAGULANT OF DIFFERENT PARTICLE SIZEV. BALAJI, S. ANAND KUMAR VARMA2 AND R. ASHWINAbstract This investigation deals with the potential utilization of Moringa Oleifera natural coagulant in the treatment of industrial effluents. This coagulant is, in general, used as point-of-use technology in less developed communities since they are relatively cost-effective compared to chemical coagulants, can be easily processed in usable form and biodegradable. The industrial wastewaters were treated by coagulation flocculation and sedimentation using Moringa oleifera as a primary coagulant. Different particle sizes are used in the treatment of industrial effluents. The experiments were conducted at various dosages of Moringa oleifera coagulant using jar-test apparatus. The optimum dosage of the coagulant dosage was identified. The physico- chemical parameters of the Wastewaters were measured before and after the treatment to evaluate the removal efficiency of the major pollutants of concern in Waste water treatment, such as pH, Turbidity, EC, and TDS. Then compared with Alum, natural coagulant gives better results. The results showed that the Moringa Oleifera seeds were resourceful as a primary coagulant in the treatment of industrial effluent.
