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 Pluronicblock 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

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

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 CarrollGeohydrology: 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.
