Abstract: The laboratory study was carried out to study the effectiveness of Moringa Oleifera and Nirmali seeds for turbidity and hardness removal of Krishna river water at Sangli, Maharashtra. The Moringa Oleifera and Nirmali seed extract was used with varying dosage of 10 mg/L to 100 mg/L, and residual turbidity and hardness was measured. Simultaneously change in pH, Alkalinity, TDS, and COD was observed. Both the natural coagulants were found effective for turbidity removal. Turbidity removal of 67 to 87 % with Moringa oleifera and 30 to 91 % with Nirmali seeds at the optimum dose of 50 mg/L was observed. For hardness removal Moringa Oleifera is more effective (7.7 to 47% removal) with optimum dose of 40 mg/L, as compared to Nirmali seeds (9.8 to 28.6 % removal). For both the coagulants no significant variation was observed in the pH and Alkalinity of water sample.TDS reduction is directly proportional to the reduction in hardness and organic matter of the water sample increases with the added dose of coagulants.
