Abstract
The shortage of obtaining secure potable water remains one of the greatest dares confronting humankind. Even with the mass universal endeavour that has been performed, the potable water fountains of at least 2 billion people are faecally polluted, conducting to more than half a million diarrheal deaths every year, with the majority taking place in poor nations. Consequently, techniques for demobilizing pathogens in the water stay of vital importance for humans. Nevertheless, traditional techniques to supply potable water, even if efficient, show restrictions that hinder their general use. Such treatment processes frequently possess elevated energy and chemical needs, which restricts their implementation for avoiding waterborne diseases. Such drawbacks have conducted for urgent investigation and expansion of advanced substitutional techniques. One such substitutional method is solar disinfection (SODIS), which is viewed as one of the most suitable techniques for assuring potable water in poor regions. This work contributes to present traditional techniques that are being utilized at medium to large scales to treat water and emerging technologies presently in expansion. Further, this communication presents briefly the advantages and shortcomings of such techniques. Special attention is accorded to SODIS, involving a fresh technique lately suggested in such domain.
