Conventional drinking water treatments are often inappropriate in developing countries, due to its high cost, lack of inappropriate infrastructures or availability of chemicals. The present study deals with the evaluation of treatment efficiency of natural coagulants Moringa oleifera, Okra seed, commonly available in nearby market. Primarily the basic operational parameters- pH and coagulant dosages were optimized. Coagulation ability of both seed extract was assessed by the use of standard jar test experiment in synthetic water with various coagulant doses. Its positive coagulation activity was measured on the basis of removal of turbidity and total dissolve solid (TDS). Best turbidity removal efficiency was achieved near neutral pH with optimal doses 200 mg/L and 220 mg/L for M. Oleifera and Okra and TDS removal efficiency was achieved with optimal dosage of 180 mg/L and 200 mg/L for Moringa oleifera and Okra.
