EVALUATION OF COAGULATION EFFICIENCY OF MORINGA OLEIFERA EXTRACT AND ALUM ON FISH POND WASTEWATER

Abstract

In this study titled evaluation of coagulation efficiency of Moringa oleifera and Alum in wastewater sample was carried out using fish pond wastewater. A preliminary investigation was carried out on initial parameters of fish pond wastewater such as turbidity, pH, BOD, electrical conductivity and total dissolve solid. Coagulant from Moringa oleifera seeds were extracted and the dosages were 2 ml, 4 ml, 6 ml and 8 ml same dose was applied to alum. Optimum dosage for percentage removal in turbidity using Moringa oleifera extract and Alum was found to be 89% and 96.8% respectively at 6 ml dose. Moringa oleifera has no significant effect on TDS, pH, EC and BOD except on BOD in which it increases the BOD. Alum increased the parameters mentioned above. Therefore, Moringa oleifera can serve as alternative coagulant to chemical coagulant alum in water and wastewater treatment.
