Solar water disinfection was performed by using TiO2 and Ru(II) complex as fixed catalysts implemented in a compound parabolic collector (CPC) photoreactor. Studies were performed in the laboratory as well as at a greenfield site. Under laboratory conditions, natural water contaminated with cultured bacteria was photocatalytically treated and the influence of the photolysis as well of both catalysts was studied. Experiments were performed with contaminated water flowing at 12 L/min, under these conditions, photocatalytic experiments performed with Ahlstrom catalyst showed it to be effective in degrading bacteria in water; the Ru-complex catalyst, however did not show clear evidence for disinfecting water and its efficiency was comparable to the photolysis. Under on-site experiments, bacteria contaminated water from the Yaurisque river at Cusco was treated. As a general trend, after photo...

 Drinking water is extremely scarce good in the world. Of the estimated 1.4 billion cubic kilometers of water on earth, 97.6% is salt, 2.38% is like ice and glaciers and only about 0.024% is above the earth's surface and therefore may be destined for human consumption. In this situation, the lack of access to drinking water is a serious problem in the world and Peru is no exception. Of the 6 billion people who inhabit the land, over a billion suffer from this problem. However, about 2.5 billion lack access to adequate sanitation. This means that more than 6 million children a year die from diseases that are caused by the water they consume.
