The powder obtained from the seeds of the M.olifera shown to be an effective primary coagulant for water treatment. In this paper, preliminary investigations M.olifera seed suspension for the softening of hard water is furnished. To analyze the influence of Moringaoleifera seeds in coagulant activity when used for natural raw water treatment. Water samples were collected from pond, tap, and the lake of Kammanahalli, HennurBande and Bagalur rural areas of Bangalore and are labeled as sample 1, sample 2 and sample 3 respectively. In each of the water sample, 25mg of dried M.olifera seed extract was added and allowed to settle for 1 hour 15 minutes. The parameters such as color, turbidity, odor and pH were analyzed before and after the inoculation of M.olifera seeds of all the three water samples. The water was analyzed for the parameters such as color, odor, turbidity, and pH. When the seeds are dried, crushed and added to water, the powder acts as a coagulant. Removal of efficiency was found to increase with increasing dosage of M.oleifera. The higher dosage was required to achieve equivalent residual hardness. Based on the results it is ascertained that seeds stored in dry containers at room temperature can be used as a coagulant for few years. Creation of awareness amongst the rural farmers on the usefulness of the M.olifera enables its cultivation which will have overall economic benefits to the entire country.
