This project will focus on the redesign, characterization and efficacy of a point of use electrolytic chlorine generator targeted for poor countries around the world for the purpose of disinfecting drinking water.


The development of an effective hand-held chlorinator is the main goal, but larger scale, flow-through systems will also be considered. The chlorine species generated by all prototypes will be characterized using wet chemistry and analytical equipment readily available to the research group. Disinfection by-product formation potential will be determined for a variety of potential source waters before and after filtration and/or coagulation/flocculation pretreatment. We will work with established organizations in the United States and abroad with international water delivery missions for effective participatory design efforts with our partner country, Haiti. The project will culminate with the installation of an electrolytic chlorinator(s) in Haiti with subsequent feedback and design improvement suggestions from the local communities that utilize the intermediate technology.
