Abstract: This study deals with the preliminary investigation on combined treatment with the coagulative ability of Moringa oleifera seeds to reduce turbidity and to determine the effectiveness of solar disinfection for the inactivation of Escherichia coli (E. coli) and coliforms on various turbid waters. Turbid water samples showed drastic reduction in microbial load and turbidity at time interval of 60 min settling with Moringa oleifera seeds at optimum dose of 0.12 gms where as solar disinfection showed drastic reduction in microbial counts (E. coli and coliforms) from too many to count to nil.

Keywords: environmental technology; water purification; Moringa oleifera; sustainability; sustainable development; turbidity; solar disinfection; Escherichia coli; E. coli; coliforms; turbid waters; microbial load.
