Abstract

The idea of decontamination by exposure to sunlight is not, in any way, a novel one. It is a traditional pra­ctice for housewives to keep bed covers, for a short whi­le, in a sunny place, and to expose white clothes to di­rect sunrays, to make them look " whiter "

This idea was grasped by a team of Lebanese resear­chers, who applied this method to disinfect small amounts of drinking water. This very method is adopted, through the present work, to the Egyptian conditions. It is found that contaminated water is perfectly fit for human consumption after being exposed to direct sunrays for a period of three hours. However, the time needed for this process depends on the type of the contai­ner used, its color, wall thickness and transmissivity, as well as on the energy of the solar radiatio·n beams, transmitted, through the container, to the polluted wa­ter. Solar disinfection of drinking water is a very simple and cheap method of acquiring pure water-. It is convenient for application in rural areas of the world, where potable , water is not found.
