Reducing Treatment Costs of Alternative Waters with Antifouling Ion-Exchange Membranes Dr. Pei Xu and Dr. Huiyao Wang Project Objectives: Reduce the costs of treating alternative waters by developing • antifouling ion exchange (IX) membranes Coat IX membranes with non-leaching, anti-adhesive, anti-microbial • nanomaterials Conduct field testing at the Brackish Groundwater National • Desalination Research Facility (BGNDRF) to treat different types of alternative waters Evaluate fouling propensity of modified membranes •

In-situ Synthesis of Antibacterial Ultrafiltration and Microfiltration Membranes with Controllable Pore Size Dr. Reza Foudazi, Department of Chemical and Materials Engineering Project Objectives: study the mesophase formation and polymerization of • antibacterial monomers Antibacterial UF/MF Membranes study the formation and polymerization of mesophases in the • Block copolymers self-assemble in the presence of water/monomer. If the presence of carbon nanotubes and graphene monomer is polymerized and the water phase is extracted, a mesoporous Investigate the effect of template (block ratio in Pluronic • polymers is produced which has the potential to be used as ultrafiltration / microfiltration (UF/MF) membranes. block copolymers) on the pore size of synthesized membranes Examine the permeability and fouling performance of • membranes Study antibacterial performance of the membranes against E. • coli

Irrigation with Brackish Groundwater and Desalination Concentrate: Effect on soil microbial properties, plant uptake, and ion deposition in soil Atriplex canescens Dr. Manoj K Shukla Project Objectives: determine the impact of irrigation with brackish • groundwater and concentrate on the size, activity and physiological profile of the soil microbial community identify salt deposition patterns with respect to the • Atriplex lentiformis drip line, and determine the plant ion uptake, corresponding • changes in stomatal conductance and photosynthetic rate, and ion balance

Assessment of Brackish Groundwater Desalination for Municipal and Industrial Water Supply in Santa Teresa, New Mexico Dr. J. Phillip King; Co-PIs: Dr. Pei Xu, Dr. Sam Fernald, Dr. KC Carroll Geohydrology: Dr. John Hawley, PG; Consultant: Ed Archuleta, PE Project Objectives: • Assess potential for brackish water desalination in the Santa Teresa area; • Characterize source water and geohydrology, treatment technologies, and disposal alternatives; • Integrate with prior and ongoing planning efforts; • Explore binational potential for water supply to San Jeronimo in Mexico; • Produce a Preliminary Engineering report and plan path forward.

Low Cost, Low Energy Concentrate Water Desalination Using Heat Recuperative Solar Still with Concentrating Solar Technology Explore and develop innovative solar collection and heat transport/management approaches for realizing a scalable, low Dr. Sarada Kuravi, Dr. Pei Xu, Dr. Krishna Kota, Dr. Huiyao Wang, Dr. Young-Ho Park cost, low energy solar still with rapid desalination capability for RO concentrate management and energy recovery Project Objectives: Amplify solar insolation to the still to enable • boiling (rapid) instead of evaporation (slow) Enhance the phase change processes i.e., boiling • rate in the basin and the condensation rate on the glass cover Make the technology based only on renewable • energy for reducing costs Build a laboratory-scale prototype at NMSU • Perform economic analysis •

Valuing the Potential Contribution of Desalination and Water Reuse to the Water Supply Portfolio of Southern Dona Ana County, New Mexico Dr. Brian H. Hurd; Co-PIs: Dr. Pei Xu, Dr. KC Carroll; Dr. J. Phillip King As we will be comparatively assessing the Kay Bailey Hutchinson Plant with the Santa Teresa plant proposal, a general breakdown of the Plant, Production Wells and Disposal costs was given from Principal, Senior Project Manager, Robert Fowlie, P.E. with CDM Smith Inc. This will help us to idealize what our potential break-down of costs may resemble. Figure 1: Shubert, A.R. (2015) Overview of the El Paso Kay Bailey Hutchinson Desalination Plant.
