Abstract

In this study, we design a point of using water disinfection and filter system using layers of bleached cotton, charcoal and sediments. We also asses the performance of ordinary charcoal compared to activated charcoal. The project also investigated the effects of exposure time on the ability of artificial ultraviolet (UV) light and solar radiation to disinfect drinking water. Preliminary results indicated that even though total coliform bacteria persisted in some treatments, most of the fecal coliform bacteria were disinfected within a day of exposure to direct sunlight. Since the samples exposed to direct sunlight had the same temperature, heat was ruled out as a factor in the disinfection process. The research is being continued to obtain sufficient data for statistical analysis and UV exposure.
