Evaluation of Moringa oleifera seed as coagulant for water treatment
Author(s): Kulkarni CP
Abstract: Water is used for several purposes by humans but the level of purity of the water being consumed is very crucial since it has a direct effect on health. In the present study efficacy of Moringa oleifera seed extract as a natural coagulant in water treatment was invistigated. Highly turbid water was collected from a river. Collected water samples were treated with varying concentrations of Moringa oleifera seed extract: 50 mg/l, 100 mg/l, 150 mg/l, 200 mg/l and 250 mg/l. The collected water samples from the river were analyzed before and after treatment with Moringa oleifera seed extracts at varying concentrations for different parameters – pH, conductivity, turbidity and total solids – to evaluate the suitability and effectiveness of moringa oleifera seed extract in treating highly turbid water. Significant reduction in all parameters analyzed with increased doses of Moringa oleifera seed extract was observed, with the exception of the pH, which remained fairly constant at all doses. It was therefore concluded that Moringa oleifera seed extract acts as a natural coagulant for the treatment of highly turbid water. This should be an encouragement for developing countries.
