Low Energy Chemical Treatment for Graywater Reuse: Mitigating Disinfection Byproducts and Recovering Cathodically Generated Hydrogen for Energy
Abstract
The goal of this project is to demonstrate the sustainable use of stable electrocatalytic anode materials to treat graywater for reuse in showers or laundry. Specific objectives include: (i) verification of effective destruction of chemical oxidation demand (COD), (ii) assessment of disinfection by products (DBP) formation relative to disinfection by products rule (DBPR2), and (iii) assessment of net energy requirements with respect to overall sustainability and costs. As part of objective (iii), cathodically generated hydrogen was be measured to evaluate its potential for offsetting the energy requirements from the cell. Successful demonstration of these objectives was inform the design of a pilot-scale system providing the DoD with a technically and economically feasible approach for graywater reuse.
