Led by Prof. Sudeep Popat, a team from Clemson has received a $750k grant from NASA to develop peroxide-producing microbial fuel cells for space life support systems application. Microbial fuel cells use a combination of microbial metabolism and electrochemical reactors to convert nutrients and energy stored in waste streams to useful chemical products. Herein, the feasibility of producing hydrogen peroxide from spacecraft blackwater containing human wastes will be investigated, followed by the application of peroxide to on-board water treatment and recycling. As part of this project, the Cates group will assess UV/H₂O₂ advanced oxidation using UV LEDs for disinfection and purification of greywater.
