“… , The average LCOW is also lower than that of standalone seawater thermal desalination systems, and the minimum value is comparable with that of a standalone seawater RO . The minimal LCOW attained is in the range proposed by the USA government for nonconventional water sources, indicating that brine concentration facilities may be able to reach pipe parity . Transportation cost, either intake from nearby desalination plants or supply to nearby population, has an average value of below 0.1 $/m 3 .…”

We propose a methodology for identifying and prioritizing the best potential locations for brine concentration facilities in the contiguous United States. The methodology uses a geographic information system and multicriteria decision analysis (GIS-MCDA) to prioritize the potential locations for brine concentration facilities based on thermodynamic, economic, environmental, and social criteria. By integrating geospatial data with a computational simulation of a real brine concentration system, an objective weighting method identifies the weights for 13 subcriteria associated with the main criteria. When considering multiple dimensions for decision making, brine concentration facilities centered in Florida were consistently selected as the best location, due to the high second-law efficiency, low transportation cost, and high capacity for supplying municipal water needs to nearby populations. For inland locations, Southeast Texas outperforms all other locations for thermodynamic, economic, and environmental priority cases. A sensitivity analysis evaluates the consistency of the results as the priority of a main criterion varies relative to other decision-making criteria. Focusing on a single subcriterion misleads decision making when identifying the best location for brine concentration systems, identifying the importance of the multicriteria methodology.

Desalination of nontraditional waters (e.g., agricultural drainage, brackish groundwater, industrial discharges, etc.) using renewable energy sources offers a possible route to transform our incumbent linear consumption model (discharge after use) to a circular one (beneficial reuse). This transition will also shift desalination from large-scale centralized coastal facilities towards modular distributed treatment plants (~1000 m3/day) in inland locations. This new scale of desalination can be satisfied using solar energy to decarbonize water production, but additional considerations, such as storage to address intermittency and inland brine management to address high disposal costs, become important. In this work, we evaluate the levelized cost of water or LCOW for 16 solar desalination technologies (with different generation–storage-desalination–brine management subsystems) at 2 different salinities corresponding to nontraditional sources. For fossil fuel-driven desalination plants at the distributed scale, we find that zero liquid discharge is economically favorable to inland brine disposal. For renewable desalination, we discover that (i) solar-thermal energy is better suited to both membrane and thermal desalination plants compared to photovoltaics largely due to the low cost of thermal storage, and that (ii) energy storage, despite its higher cost, outperforms water storage on a levelized basis as the latter has a low utilization factor with intermittently operated desalination plants. The analysis also yields a promising outlook for the LCOW of solar desalination by 2030 as the costs of solar generation and energy storage decrease to meet the U.S. Department of Energy targets. Finally, we highlight subsystem cost and performance targets for solar desalination to achieve cost parity with fossil fuel-driven water treatment.

“…These decision-relevant metrics can include cost, reliability, energy use, technical performance, regulatory requirements, potential for integrating renewable energy, and other factors. 23 Achieving pipe parity is critical to enable increased mine water reuse. Pipe parity for a technology application in the mining sector may be different from pipe parity for the same technology in other sectors.…”

“…Pipe parity is defined by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) as “technology solutions that are cost competitive with existing water sources and end-use applications.” In our assessment, mine water reuse will achieve pipe parity when a new technology or set of technologies could treat mine water such that it is seen as an equally desirable source to other water supply options (i.e., their marginal water source), accounting for various decision-relevant metrics. These decision-relevant metrics can include cost, reliability, energy use, technical performance, regulatory requirements, potential for integrating renewable energy, and other factors …”

Mine Water Use, Treatment, and Reuse in the United States: A Look at Current Industry Practices and Select Case Studies

et al. 2021

Mining provides significant economic value while often impacting local water supplies and environments because of freshwater usage and waste disposal practices. This study identifies current practices in mine water, including how water is used in mining, influent and effluent water quality, treatment technologies, and end uses with the goal of informing future research on implementable, reliable, and cost-effective advanced water treatment in the mining sector. This study also reviews the available literature to broadly evaluate mining in the United States and performs a techno-economic assessment on water use and disposal for three detailed case studies applicable to lithium, uranium, and copper mines. These case studies highlight specific industry examples of distinct extraction methods, geographical regions, and mined commodities. Hypothetical scenarios based on case study baselines revealed potential impacts to mine water available for beneficial reuse through the use of novel water treatment technologies and alternate water management strategies. Finally, an assessment of national level impacts resulting from the reuse of treated mine source water is presented.
