Moringa oleifera; natural coagulant; turbidity removal
In developing countries pond water is still widely used for drinking and household purposes, which develops higher turbidity during rainy seasons and requires a large amount of chemical coagulants, and this leads to high cost of treatment. To mitigate this, it is important to find an economical and natural coagulant to treat turbid water. The present study is focused on using a plant based component as a natural coagulant that is sustainable and environment-friendly. This work focuses on the extraction, isolation and purification of a natural coagulant from seed kernels of Moringa oleifera to enhance its turbidity removal efficiency. The determination of themolecular weight of the purified proteins was done using sodium dodecyl sulfate polyacrylamide gel electrophoresis. The active coagulant proteins were isolated using 30-60% and 60-80% saturation of ammonium sulfate. It was observed that proteins with molecular weight less than 36 kDa have superior coagulation activity. Turbidity removal efficiency of these active coagulant proteins was compared with alum. The possibility of using Moringa oleifera seeds as a natural antimicrobial agent was also investigated.
