"perpetual devotion to what a man calls his business, is only to be sustained by perpetual neglect of many other things"
This Wednesday, April 23rd, sees the final of the government-backed Unipreneur Awards, sponsored by HSBC Bank and presented in association with the National Council for Graduate Entrepreneurship. "Studies have shown that improving the microbiological quality of household water by on-site or point-of-use treatment and safe storage in improved vessels reduces diarrheal and other waterborne diseases in communities and households of developing as well as developed countries. The extent to which improving drinking water quality at the household level reduces diarrheal disease probably depends on a variety of technology-related as well as site-specific environmental and demographic factors that require further investigation, characterization and analyses. Reductions in household diarrheal diseases of 6-90% have been observed, depending on the technology and the exposed population and local conditions.
The most promising and accessible of the technologies for household water treatment are filtration with ceramic filters, chlorination with storage in an improved vessel, solar disinfection in clear bottles by the combined action of UV radiation and heat, thermal disinfection (pasteurization) in opaque vessels with sunlight from solar cookers or reflectors and combination systems employing chemical coagulation-flocculation, sedimentation, filtration and chlorination. All of these systems have been shown to dramatically improve the microbiological quality of water.
Further development, refinement, implementation, evaluation and comparison of household water treatment and safe storage technologies is both justified and encouraged."
