FRISCO, TX  WateReuse Texas has awarded Garver a $50,000 grant to further research advanced oxidation processes for potable water reuse. 

"Water-scarcity and drought-resiliency are major drivers for increased potable reuse. Major obstacles to increased acceptance of potable reuse include residual contaminants of emerging concern in advanced wastewater effluents," said Dr. Michael Watts, Senior Process Engineer at Garver. "This project will explore new, cost-effective, advanced oxidation solutions to improve the quality of these alternative water supplies." 

The six-month study, entitled Optimizing selection of filtration pretreatment and chemical oxidant for UV advanced oxidation of potable reuse waters,  will begin in July 2016. During that time, Garver and its partners will compare the efficiency of removing contaminants of emerging concern from sampled membrane permeate- and conventional media-filtered effluents with a UV Advanced Oxidation pilot reactor to be located at the Cypress Water Treatment Plant in Wichita Falls, Texas. Wichita Falls is currently permitted to treat River Road WWTP secondary effluent for direct potable reuse (5 million gallons per day) with an advanced separation system consisting of series microfiltration and reverse osmosis membranes. For comparison purposes, conventional media-filtered effluents will also be sampled from the nearby Lawton WWTP in Lawton, Oklahoma.
