Use of Moringa Oleifera Seeds as a Natural Coagulant in Treatment of Waste Water of Electroplating Industry

The quality and accessibility of drinking water are of chief importance to human health. The chief objective of this work was to use Moringa oleifera seeds as a natural coagulant in electrocoagulation procedure for the handling of electroplating industry wastewater. It is found that Moringa oleifera is the superlative bio coagulant that can be a substitute of aluminum sulfate (alum). The effectiveness of Moringa oleifera seed cake in eliminating heavy metals ions such as copper, chromium, zinc, lead, and cobalt from the wastewater sample by means of jar test trailed by electrocoagulation process was very much reliable. The subtraction of heavy metal ions observed for Moleifera seeds treated water were 50% for copper, 79% for lead, and zinc, and more than 90% for chromium and cobalt, at an optimal dosage of 200mg/L. Around 90-96% of turbidity has been reduced from the wastewater by Moringa oleifera seed cake, though it has a no glaring effect on the pH which is also an advantage.
