An alternative disinfectant, hydrogen peroxide (H2O2), leaves only water and oxygen as byproducts. Moreover, H2O2 works over a wider pH range than chlorine, so it can treat water with diverse quality. However, cost and safety concerns make H2O2 inaccessible to a large percentage of people who need it the most. This project will design, build and test a prototype solar-powered water treatment system. The system will electrochemically convert water and oxygen to produce levels of H2O2 sufficient to remove pathogens, odors and metals from water.
