An Experimental Study on Treatment of Wastewater Utilizing Moringa Oleifera and Vigna Unguiculata Seeds: A Sustainable Approach

Abstract

Wastewater treatment requires coagulants in a sedimentation-filtration stage for which effective coagulants were needed. Moringa oleifera and Vigna unguiculata shows adequate water-soluble proteins that show active coagulant properties. Jar test analysis shows that chemical coagulant Alum gives optimum dosage at 2ml volumetric dosage while in comparison to that, M. oleifera gives optimum dosage at 4ml volumetric dosage and Vigna unguiculata at 5ml volumetric dosage for collected wastewater. A comparative study shows that both Natural coagulants show active turbidity removing efficiency at a little higher volumetric dosage. For various concentrations from 2%, 4%, and 6%, both natural coagulants have the most soluble required solution effect at 2% concentration, which helps in effective removal of residual turbidity. Preparation of natural coagulants solution is effortless and have fewer environment impacts than chemical coagulant, the usefulness of this natural coagulant will be helpful to meet with eco-friendly treatment and a better sustainable approach.
