The Department of the Interior Bureau of Reclamation awarded a $1,001,044.18 Cooperative Agreement to Carollo Engineers Inc. on August 24, 2023 under the SECURE Water Act - Research Agreements program (CFDA 15.560). The project will test an in-situ resin regeneration process using bicarbonate for potable water reuse applications. This approach aims to remove dissolved organic matter and inorganic anions such as nitrate, nitrite, phosphate, and others from the water without producing the large volumes of waste concentrated generated by reverse osmosis-based treatment. By coupling ion exchange and softening processes, the in-situ resin regeneration method is expected to provide multiple treatment barriers for both inorganic and organic contaminants, thereby improving the overall treated water quality compared to traditional carbon-based advanced treatment. The project will run through March 31, 2025.
