Research for the Development and Use of Alternative Water Supplies

A Cooperative Agreement Project Between New Mexico State University and the U.S. Bureau of Reclamation

Two projects have been completed and reports co-published by NM WRRI and Reclamation

Reducing Treatment Costs of Alternative Waters with Antifouling Ion-Exchange Membranes

• Dr. Pei Xu and Dr. Huiyao Wang
• 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

Project Objectives:

Block copolymers self-assemble in the presence of water/monomer. If the monomer is polymerized and the water phase is extracted, a mesoporous polymers is produced which has the potential to be used as ultrafiltration / microfiltration (UF/MF) membranes.

Antibacterial UF/MF Membranes

• study the mesophase formation and polymerization of

antibacterial monomers

• study the formation and polymerization of mesophases in the

presence of carbon nanotubes and graphene

• Investigate the effect of template (block ratio in Pluronic

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.

In-situ Synthesis of Antibacterial Ultrafiltration and Microfiltration Membranes with Controllable Pore Size

• Dr. Reza Foudazi, Department of Chemical and Materials Engineering

Project Objectives:

Irrigation with Brackish Groundwater and Desalination Concentrate: Effect on soil microbial properties, plant uptake, and ion deposition in soil

• 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

drip line, and

• determine the plant ion uptake, corresponding

changes in stomatal conductance and photosynthetic rate, and ion balance

Project Objectives:

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.

Assessment of Brackish Groundwater Desalination for Municipal and Industrial Water Supply in Santa Teresa, New Mexico

EBID, based on Hawley

• Dr. J. Phillip King; Co-PIs: Dr. Pei Xu, Dr. Sam Fernald, Dr. KC Carroll

Geohydrology: Dr. John Hawley, PG; Consultant: Ed Archuleta, PE

Explore and develop innovative solar collection and heat transport/management approaches for realizing a scalable, low cost, low energy solar still with rapid desalination capability for RO concentrate management and energy recovery

• 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

Low Cost, Low Energy Concentrate Water Desalination Using Heat Recuperative Solar Still with Concentrating Solar Technology

• Dr. Sarada Kuravi, Dr. Pei Xu, Dr. Krishna Kota, Dr. Huiyao Wang, Dr. Young-Ho Park

Project Objectives:

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.
