Water Reuse – using reverse osmosis as a strategy to reclaim water in drought affected areas
Water reuse is receiving increasing attention as a strategy that can improve reliability and drought resistance of water supplies. Civil and Environmental Engineering faculty, Dr. Daisuke Minaka, was awarded new funding from the University of New Mexico to develop a comprehensive model that can predict the removal efficiency of numerous organic chemicals in the reverse osmosis (RO) process in reclaiming wastewater. Wastewater reclamation plants use a combination of membrane and reverse osmosis technologies with advanced oxidation to make sure that trace level of organic chemical contaminants such as pharmaceuticals, personal care products, endocrine disrupting chemicals and disinfection byproducts are effectively removed using multi-barrier concepts. The RO model will use a combination of a mathematical model and sophisticated computational chemistry molecular modeling. The team hopes to utilize this tool as a holistic predictive tool to predict the removal efficiency for the new chemical compounds that may be under consideration of future regulations.
