The University of Oklahoma, through its Office of Research Administration, was awarded a $300,000 project grant from the U.S. Department of Agriculture's Agriculture and Food Research Initiative (CFDA 10.310) to develop and test low-cost materials for the treatment of brackish water. The project aims to treat two model brackish water compositions from Texas and California, primarily focusing on the removal of chloride anions and sodium cations. The treatment methods involve adsorption to calcined layered double hydroxides, precipitation of calcium chloroaluminate, and the use of cellulose-based cation exchange polymers derived from wheat straw and corn cobs. The goal is to produce treated water with total dissolved solids below 500 mg/L, potentially reducing the demand for freshwater use in agriculture and increasing the resilience and sustainability of food production. The project is scheduled to run from August 1, 2024, to July 31, 2026.
