A comparison between Moringa oleifera and chemical coagulants in the purification of drinking water – An alternative sustainable solution for developing countries

A research project was commissioned to investigate the performance of Moringa oleifera compared with that of aluminium sulphate (Al 2(SO 4) 3) and ferric sulphate (Fe 2(SO 4) 3), termed alum and ferric respectively. A series of jar tests was undertaken using model water, different raw water sources...

Description
Summary:A research project was commissioned to investigate the performance of Moringa oleifera compared with that of aluminium sulphate (Al 2(SO 4) 3) and ferric sulphate (Fe 2(SO 4) 3), termed alum and ferric respectively. A series of jar tests was undertaken using model water, different raw water sources and hybrid water containing a mixture of both of these types of water. The model water consisted of deionised water spiked with Escherichia coli (E. coli) at 10 4 per 100 ml and turbidity (146 NTU) artificially created by kaolin. Results showed that M. oleifera removed 84% turbidity and 88% E. coli, whereas alum removed greater than 99% turbidity and E. coli. Low turbidity river water (
