The National Science Foundation awarded a $499,999 Project Grant to the University of Colorado Boulder under the Engineering (47.041) federal grant program. The award period is January 1, 2023 through December 31, 2025.
The grant funds research to develop an integrated oxidation vapor-gap reverse osmosis system to more efficiently reuse wastewater for potable purposes. The project aims to determine how pre-oxidation treatments transform model wastewater contaminants and impact their rejection in vapor-gap reverse osmosis. Researchers will also evaluate the effects of ozonation and chlorination on membrane properties and fouling behavior. Working with industrial partner Trussell Technologies, the team will test the performance of an integrated ozonation-vapor gap reverse osmosis process in treating actual wastewater to meet contaminant removal benchmarks.
The University of Southern California will receive a $50,000 subaward to support specific tasks including developing models for predicting contaminant abatement during wastewater oxidation and evaluating organofluorine byproduct formation from oxidizing vapor-gap membranes. Results aim to advance vapor-gap reverse osmosis integrated with oxidation for potential alternative water reuse practices.
