Moringa oleifera- A Herbal Coagulant for Wastewater Treatment

Moringa oleifera is a multipurpose, medium or small-sized tree, from regions of North West India and indigenous to many parts of Asia, Africa, and South America. Its pods are a non-toxic natural organic polymer, which have been employed as an inexpensive and effective sorbent for the removal of organics, and coagulant for water treatment. The main objective of this work was to use the Moringa oleifera seeds as a natural adsorbent for the treatment of dairy industry wastewater. In present study various doses of Moringa oleifera seed coagulant viz.100 mg/L, 200 mg/L and 400 mg/L were taken and checked for the efficiency dose on treated and untreated wastewater. After treatment of water samples with Moringa oleifera coagulant were analyzed for different parameter like pH, turbidity, COD and salinity. All parameters were reduced with increased dose of Moringa oleifera except pH. Application of this low cost Moringa oleifera seed coagulant is recommended for ecofriendly non toxic, simplified waste water treatment.
