Two-Stage Metal Treatment Incorporating Basic Oxygen Furnace Slag and Microbiological Sulfate Reduction
A consistent environmental challenge presented at mining sites worldwide is the formation of mining-influenced water (MIW). Characterized by alterations in water chemistry due to mining or mineral processing, MIW streams are typically acidic and often contain elevated concentrations of heavy metals and metalloids, which may pose a threat to human health,...

Electro-Regeneration of PFAS-Laden and Spent Sorbents for Reuse as Sustainable Water Treatment
Background Adsorption is the main water treatment technology that is commercially used to remove per- and polyfluoroalkyl substances (PFAS) from water. These substances are in thousands of everyday products due to their high stability and chemical resistance, but are non-biodegradable and can pose risks to human health. Current adsorption techniques...

Atomic Hydrogen Provision by Cobalt Sites for Superior Ammonia Production
Background Ammonia (NH3) is a valuable compound for industrial, agricultural, and water treatment applications. The typical method for large-scale production of ammonia is the Haber-Bosch (HB) process, which uses hydrogen and nitrogen as reagents under high pressure and temperature. However, this process generates over 450 million tons of CO2 annually,...

Atmospheric Water Generation by a Hybridized Rotary Dessicant with Solar-Heated Evacuated Tubes
Background Water harvesting from ambient air to produce fresh water is an active area of research. Water moisture in the air is universally available, and the water extracted is essentially pure water. This makes this process ideal, particularly for communities with limited freshwater supplies. Atmospheric Water Generation (AWG) technology can produce...

Enhancing Strength of EICP-Treated Sand Using a Protein-Based Additive
Background Effective ground improvement methods are essential for optimal utilization of land, whether they be roads, embankments, dunes, or slopes. Conventional methods using compaction, pile insertion, and cement-soil mixing provide adequate stability but have several major drawbacks. They are often expensive, time-consuming, require specialized...

High-Efficiency Photocatalytic H2O2 Production
Background Hydrogen peroxide (H2O2) is widely used for industrial synthesis of organic chemicals, advanced oxidation of drinking or wastewater, and surface disinfection of pathogens. Currently, ~95% of H2O2 production employs the energy- and chemical-intensive anthraquinone-oxidation process. Photocatalytic H2O2 production is an emerging alternative...

Membrane Contactor for Simultaneous Desalination and Co2 Removal From Seawater
Background To address the pressing issue of climate change resulting from excessive CO2 levels in our atmosphere, an array of innovative negative emission technologies must be scaled and implemented for carbon removal. Discussions concerning these technologies often surround Direct Air Capture (DAC); however, Direct Ocean Capture (DOC) is an exciting...

Parallel In Situ Screening for Optimizing Remediation Strategies for Saturated Contaminated Sites
In situ bioremediation holds great promise as a safe and cost-effective strategy for cleanup of contaminated sediments and groundwater. The design of bioremediation systems requires site-specific characterization of the types of microorganisms present, what their potential metabolic capabilities are, and to what extent these degradative functions are...

Methods and Systems for Ultra-trace Analysis of Environmental Waters
Many sites with ground and/or surface water pollution have been identified across the United States. For site characterization, exposure and risk assessment as well as remediation monitoring, it is important to analyze the environment for toxic contaminants at trace levels. However, this sensing is often expensive, especially when attempting...

Soil Inoculants for Restoration of Degraded Arid Soils
Large swaths of arid land are under severe, increasing anthropogenic stress, with degrading or already degraded soils. Regeneration of biocrusts, photosynthetic communities which act as the natural biological cover of arid soils and increase nutrients into them, has promise for dryland restoration and sustainability. However, unaided recovery of biocrust...
