MOWLI, P.P., 1990. Drumstick seed as a coagulant. IN: Smith, M.D. (ed). Infrastructure for low-income communities: Proceedings of the 16th WEDC International Conference, Hyderabad, India, 27-31 August 1990, pp.131-134.
The results of investigation using drumstick seed power as a natural coagulant are reported. The raw waters used for experimental work encompassed turbidity values ranging from 32 to 210 NTU. and, PH values ranging from 6.5 to 9.1. The results of the work clearly indicate the effectiveness of the drumstick seed as a coagulant and compares well with alum for treatment of turbid waters. The findings of the work will be of immediate application in rural water supplies in the developing countries.
This is a conference paper.
