The objectives of this research project are to reduce the costs of treating alternative waters by developing low-cost antifouling ion exchange (IX) membranes. To achieve the goal of the project, we will: (i) coat commercial IX membranes with non-leaching, anti-adhesive, anti-microbial materials such as TiO2 nanoparticles and graphene oxide (GO) nanoflakes in polymers; (ii) evaluate fouling propensity and cleaning efficiency of modified membranes; (iii) conduct laboratory and field testing at the Brackish Groundwater National Desalination Research Facility (BGNDRF) in Alamogordo treating different types of alternative waters to assess IX membrane performance, fouling propensity, and desalination efficiency under representative operating conditions; (iv) conduct cost analysis to evaluate the benefits of the antifouling IX membranes for treating alternative waters.
In order to help meet the NMSU and Reclamation goals in the cooperative agreement, the goal of the directed research is to provide a tool that shows how advanced water treatment could impact water budgets in the lower Rio Grande of New Mexico. The objectives are: 1) develop an integrated tool based on local application of AWT with a system dynamics model of associated hydrology, water quality, environmental impacts, agriculture, urban, and total cost; 2) create an effective tool to envision utilization of brackish aquifers in all New Mexico planning regions that will be the backbone of a new effort that is expected to expand beyond the original Mesilla and Hatch Valley site encompassed in the Lower Rio Grande planning region for New Mexico.
This project contributes to the process of examining several of the economic, social, and environmental aspects of securing additional water supplies for Southern New Mexico. We will explore and exam several aspects including, economic development, infrastructure and water resource limitations, at-risk and disadvantaged communities, and the risks of climate change. The primary objective is to develop and apply a coupled hydro-economic and behavioral model that identifies and evaluates economic, societal, and environmental impacts from including brackish groundwater desalination and/or wastewater reuse in a portfolio of water supply alternatives that enhances the sustainability and economic development of Southern New Mexico.
Disposal of concentrate from brackish water desalination is limited by concerns of salt leaching into fresh water sources. Prevention of salt leaching can greatly increase desalination concentrate management costs and there are few options to recover those costs. One cost-recovery option for desalination concentrate disposal is using the concentrate as irrigation water for producing halophyte biomass for forage and for other applications. The purpose of this project is to determine how much of the salt taken up by the halophyte crops can be protected from leaching by pyrolysis of the harvested biomass. Results from this research will be useful for those managing high salinity biomass streams, such as halophyte crop wastes and animal manures, and those seeking alternate disposal options of produced water from oil/gas extraction with a possible potential for economic and/or environmental returns. The ability to sequester salt in biochar would decrease the negative impacts from land-applications of high-salinity materials, including those used in desalination concentrate management systems.
Results from this research on two species of Atriplex, halophyte forage shrubs native to the Southwest, show that salts taken up in the biomass are concentrated into the biochars during pyrolysis and that pyrolysis conditions affect the amount of salt that can be leached with water. Increasing pyrolysis temperature increases the retention of calcium and magnesium ions but gives less consistent trends for the retention of potassium and sodium. The retention of at least some salt in the short-term suggests that, with more understanding of the salt formation and
retention mechanisms, and optimization of the system, higher amounts of salt could be sequestered longer, while taking advantage of the carbon sequestration and soil quality benefits of biochars.
The area around Santa Teresa, New Mexico is a bright spot for economic development in the state, with a land port of entry (LPOE) to Mexico, the largest border crossing for cattle in the country, a huge Union Pacific intermodal transportation facility, and a growing industrial base. Large-scale development is also planned for the Mexican side of the LPOE, and the binational development will be economically integrated. One limiting constraint on the area’s growth is access to fresh water. Currently, the Camino Real Regional Water Authority (CRRUA) relies entirely on the fresh groundwater in the area. With very limited recharge and interaction with brackish and saline aquifers, the local fresh groundwater is quite limited, and responsible development in the area will require a more diverse water supply portfolio (Villagran 2016). While fresh groundwater is limited in the area, there is a vast quantity of brackish (total dissolved solids (TDS) in the range of 1,000-10,000 mg/L) and saline (10,000-100,000 mg/L) groundwater in the Mesilla aquifer system in southern New Mexico and northern Chihuahua in the vicinity of the Santa Teresa-San Jeronimo area.
The proposed research will examine the hydrogeologic as well as the technical and economic potential for use of desalinated brackish groundwater in the Santa Teresa-San Jeronimo area, conduct a proof-of-concept demonstration with a pilot desalination plant and existing brackish wells, and, if the concept appears feasible, develop an organizational and financial plan for moving forward with desalination implementation. Specifically, the research will work with the CRRUA and the Border Industrial Association to assess demand and binational development potential, characterize the source, examine concentrate disposal options, identify treatment alternatives and potential costs, and set in motion a coordinated effort to bring desalination capacity to the Santa Teresa area.
This proposal will determine the accumulation patterns of various ions in soil that is drip-irrigated with reverse osmosis (RO) concentrate. It will quantify the impact of RO concentrate application on soil microbial properties, ion accumulation, plant ion uptake, and forage quality of Atriplex canescens and A. lentiformis. The objectives are to:
a. determine the impact of irrigation with brackish groundwater and concentrate on the size, activity and physiological profile of the soil microbial community
b. identify salt deposition patterns with respect to the drip line, and
c. determine the plant ion uptake, corresponding changes in stomatal conductance and photosynthetic rate, and ion balance
The overarching goal of the proposed study is to explore and develop innovative solar collection and heat transport/management approaches in a bottom-up thermal process design for realizing a scalable, low cost, low energy solar Still with rapid desalination capability for RO concentrate management and energy recovery.
This research has the following objectives:
(1) Amplify solar insolation to the Still to enable boiling (rapid) instead of evaporation (slow)
(2) Enhance the phase change processes i.e., boiling rate in the basin and the condensation rate on the glass cover to improve the efficiency of the Still
(3) Make the technology based only on renewable energy for reducing costs
(4) Build a laboratory-scale concentrate solar Still at NMSU to demonstrate the water production and fouling/scaling potential during treating RO concentrates from the evaporation ponds
in Brackish Groundwater National Desalination Research Facility
(5) Perform cost estimates with experimental data and modeling projections, which allows process optimization, identifies economic scale, and comparison with other technologies.
The objectives of this project will be achieved through systematic experiments and theoretical analysis. A laboratory scale Still will be built for experiments to primarily demonstrate the aspects of cost-effectiveness, amplified solar insolation, heat recuperation, and enhanced phase change heat transfer.
New Mexico (NM) is in a long-term drought that threatens the sustainability of the agricultural industry as well as drinking water supply, and a desalination plant is proposed (i.e., Santa Teresa) as an alternative (i.e., brackish) water use. Producing “new/alternative” water from unused brackish zones is attractive for augmenting drought and to support water resource development. However, we do not know if the brackish water formations are permeable enough to produce source water for a desalination plant, and we have not evaluated the potential impacts this will have on the hydrologic system (e.g., drawing fresh water into saline formations, land subsidence, surface water declines). We also do not know how much flow, mixing, and salinity transfer occurs between the shallow and deeper and/or fresh and brackish aquifers. We have a lack of detailed geochemical and isotopic data for brackish water, because brackish water has not been used extensively in the past. We do not know how sustainable our water resources are, because we have not characterized the storage, flow dynamics, and resiliency of the groundwater system, especially for the brackish aquifers.
This project will use geochemical and isotopic signatures to characterize the age (and residence time) and sources (and mixing) of fresh and brackish groundwater at various depths within the Mesilla Aquifer system. The objectives of the study are to characterize the fresh and brackish groundwater system in the Mesilla Basin, and assess the impact of brackish production for desalination on fresh water sustainability. Geochemical and isotopic tracers will be used to pursue these objectives, as well as to evaluate the potential for cross-basin recharge from the adjacent basins. This study will identify the sources and determine the rates of recharge of the Mesilla Basin groundwater by employing aqueous isotopes in a multi-tracer approach to characterize groundwater movement. Specifically, we will determine and evaluate the concentrations of the isotopes of 18O, 2H, 3H, 39Ar, 81Kr, 85Kr, 13C, 14C, and 3He. The data collected will be used to (1) identify the sources of recharge, (2) determine groundwater residence times (age-dating), (3) estimate rates of recharge, and (4) estimate mixing and sources of salinity. The scope of work will involve collecting groundwater samples from wells within the basin that are screened at various depths and represent both brackish and fresh water conditions. The geochemical and isotopic composition of the samples will be determined to characterize groundwater source end-members and to calculate the mixing amounts between brackish and fresh zones of the Mesilla Bolson aquifer. Reactive transport modeling of these aquifer zones and the collected isotopic and geochemical data will examine the potential impacts of brackish water production and desalination plant concentrate injection into subsurface formations for disposal.
Our project objective is to tailor locally-available, modern analytical instrumentation capability for the characterization of impaired water sources. This technology development will allow the Chemical Analysis and Instrumentation Laboratory (CAIL) to provide innovative feedback to multidisciplinary teams of water researchers in New Mexico and beyond at an unprecedented level of specificity.
Our specific approach involves developing instrument operating routines, instrument modification, sample preparation methods and data interpretation mechanisms for our ultrahigh resolution mass spectrometers that allow us to observe contaminants and other organic compounds in water samples.
The aim of this study is to produce antibacterial ultrafiltration (UF) and microfiltration (MF) membranes for water and wastewater treatment without the need for costly, post-synthesis functionalization or hazardous solvents. In order to accomplish this aim, mesophases will be made using Pluronic block copolymers with different block ratios in the presence of anti-bacterial monomers with trimethylammonium chloride functional groups. Through the polymerization of monomers and subsequent removal of the block copolymers, mesoporous polymers will be produced that can serve as UF or MF membranes, depending on the pore size, which will be manipulated through the block ratio of the block copolymer. We hypothesize that block ratio in Pluronic block copolymers, polyethylene oxide/polypropylene oxide (PEO/PPO), can affect the pore size of final membranes. In order to study the effect of block ratio (PEO/PPO), we need to choose Pluronic block copolymers with the same wt.% of PEO(PPO) and different PPO(PEO).
Antibacterial MF or UF membranes can be used in the pretreatment stage to not only remove suspended particles and macromolecules, but also to disinfect the water. Self-assembly of Pluronic block copolymers with different block ratios in the presence of [2-(acryloyloxy) ethyl] trimethylammonium chloride (AEAC) or (3-acrylamidopropyl) trimethylammonium chloride (APAC) and N,N′-methylenebis(acrylamide) (MBA) will yield different mesostructures with different channel sizes, which will then be cast as thin films on a support and polymerized to produce antibacterial membranes. Final membranes will be studied in terms of antibacterial performance, permeability, and biofouling.
In our investigations, in order to improve the order and having control over the alignment of liquid crystals, we are going to use additives like carbon nanotubes, silver nanowires and/or graphene in our system. By using these additives, we are going to achieve the following goals:
