In this paper, use of Moringa oleifera seeds for purifying water is discussed. A study was carried out to know the efficiency of Moringa oleifera seed suspension for removal of turbidity and hardness of water. Turbid water sample of low turbidity (50 mg/L) was prepared in the laboratory using bentonite clay, kaolin clay and black cotton soil. Moringa oleifera seed suspension was added as coagulant in concentration of 20, 40, 60, and 80 mg/L. The hardness removal efficiency was checked on water sample from tube well in the vicinity of Aurangabad city (India). The initial hardness of water sample was 284 mg/L. The dosages of Moringa Oleifera seed suspension were 125, 250, 375 and 500 mg/L. In addition to hardness, effect on pH, electrical conductivity, total dissolved solids and salinity was also studied. Moringa Oleifera seed suspension was found to be effective in treating the water.
