Abstract

The bacterial inactivation efficacy of a solar water disinfection (SODIS) reactor consisting of a 25 L borosilicate glass tube fitted witha compound parabolic collector (BGTR-CPC) was assessed under equatorial weather conditions in Uganda. The SODIS BGTR-CPCwas tested over a 17 month period in Sub-Saharan conditions in Kampala, Uganda. The BGTR-CPC was filled with natural water froma nearby protected well. A wild strain of Escherichia coli isolated from local natural water was added to the reactor to give a startingpopulation of between 105 and 107 CFU/100 ml. This spiked water was exposed to natural sunlight. Satisfactory bacterial inactivation(log10 reduction values >6 units or inactivation to below the limit of detection (
