Wastewater Treatment

Research in wastewater treatment addresses the critical need for safe and effective methods to manage and purify water resources. This field investigates novel approaches to remove a wide range of contaminants, including conventional pollutants, emerging contaminants of concern such as pharmaceuticals and microplastics, and pathogens. Studies employ advanced analytical techniques to characterize wastewater composition and explore innovative treatment processes. These processes often involve the development and application of new materials, such as advanced membranes and nanomaterials, for enhanced separation and degradation of pollutants. Research also examines the biological and chemical mechanisms underlying treatment efficacy and the potential for resource recovery from wastewater streams.

This work holds significant relevance for Arkansas, a state with extensive agricultural operations and a growing industrial base, both of which generate substantial wastewater. Effective wastewater treatment is essential for protecting the state's vital water bodies, including the Mississippi River and the Ozark aquifers, which are critical for drinking water, agriculture, and recreation. Furthermore, advancements in wastewater treatment contribute directly to public health by preventing the spread of waterborne diseases and ensuring the safety of recreational waters. The development of sustainable treatment technologies can also support economic growth by enabling water reuse and reducing the environmental footprint of industries.

This research area draws upon expertise in environmental science, materials science, and public health. Investigations into nanoparticle applications and antimicrobial resistance are closely integrated, reflecting a comprehensive approach to understanding and mitigating risks associated with wastewater. Engagement across multiple Arkansas institutions ensures a broad base of knowledge and collaborative potential for addressing complex water quality challenges.
