Point-of-use disinfection technologies currently prescribed for the provision of safe water are not always completely effective in the challenging surface waters common to developing regions. This poster presentation will summarize efforts to characterize and improve the efficacy of several POU technologies. These efforts focused on controlling the full spectrum of pathogens, particularly viruses, in waters heavily influenced by human waste. Processes investigated include chlorination, coagulation, biosand filtration, solar disinfection, photocatalysis and zeolite ion exchange. Effects of turbidity, ammonia and/or natural organic matter on these processes, along with methods for mitigating these effects, will be discussed.
