The Aquatic Innovations in Materials Science (AIMS) Lab conducts research at the intersection of environmental engineering and materials science to realize creative solutions to pressing urban water supply challenges.
Traditionally, environmental engineers have viewed the urban water supply in a linear approach where drinking water sources (e.g., rain, surface, and groundwater) are used, treated, and then discharged.
A more sustainable approach is to view waste water in a circular economy model where resources are extracted and reused to maximize value from a given material or process.
Applied in this context, a circular approach to wastewater means potable reuse following a series of advanced treatment processes.
Unfortunately, the presence of industrial chemicals, pharmaceuticals, urban-use pesticides, and other contaminants, and the uncertainty of contaminant transformation during treatment pose a threat to human and environmental health.
New technologies and approaches are needed to remove toxic contaminants and recover additional value from wastewater to help realize these water reuse strategies towards a more circular wastewater approach.
Our research interests bridge materials science and surface chemistry with traditional water quality techniques to investigate ways to increase urban water supply sustainability. Research directions in the AIMS lab will range from identifying mechanisms of target species-substrate interactions to inform new materials design, to large-scale materials synthesis for field-level water treatment in more applied urban water systems.
More specifically, our research aims to:
- develop low-cost, materials for selective removal of toxic and persistent trace organic compounds in wastewater
- engineer new media for urban stormwater contaminant removal and investigate opportunities for applying media in the urban landscape
- modify conventional adsorbents to increase nutrient capture and recovery from contaminated waters
