Impact of Moringa Seed Extract on the Physicochemical Properties of Surface and Underground Water

A.O. Oluduro and B.I. Aderiye    

Abstract: An investigation on the impacts of Moringa seed extract on the physicochemical properties of surface and underground water in Ado-Ekiti, Nigeria was carried out. Moringa oleifera seed contains 37.8% protein, 36.2% fat, 3.67% crude fibre and 9.48% ash. It is also rich in magnesium (129.6 mg L-1), potassium (103.5 mg L-1), sodium (70.1 mg L-1), calcium (34.6 mg L-1) and iron (5.4 mg L-1). The seed extract lowered the pH of the water samples while the concentration of some essential minerals such as potassium, sodium, iron and magnesium increased appreciably after the seed treatment. The Biological Oxygen Demand (BOD5) value observed in Moringa treated surface water sample was greater (4.0 mg mL-1) than that obtained in underground water sample (1.2 mg mL-1). The seed extract achieved 90 and 95% sedimentation of the suspended particles in underground and surface water samples, respectively. Sedimentation was best achieved with 0.03 mg mL-1 of the seed extract.
