Wastewater Treatment

Research in wastewater treatment focuses on developing and improving methods for purifying water and managing wastewater streams. Investigations explore the removal of a wide range of contaminants, including organic pollutants, heavy metals, and emerging contaminants like pharmaceuticals and microplastics. Studies employ diverse techniques such as advanced oxidation processes, adsorption using novel materials, membrane filtration, and biological treatment strategies. A significant area of inquiry involves the synthesis and application of new materials, including nanoparticles and electrocatalysts, to enhance treatment efficiency and reduce operational costs. The fundamental understanding of chemical and physical processes governing contaminant removal is a key objective.

This research holds particular relevance for Arkansas, a state with significant agricultural and industrial sectors that generate substantial wastewater. Effective wastewater treatment is crucial for protecting the state's abundant natural resources, including its rivers, lakes, and groundwater, which are vital for public health, recreation, and the economy. Addressing nutrient runoff, particularly phosphorus from agricultural sources, is a critical environmental challenge in Arkansas, and advancements in wastewater treatment offer solutions for nutrient management and mitigation of eutrophication in state waterways.

This work draws upon and contributes to interdisciplinary fields such as materials science, environmental science, and electrochemistry. Investigations into adsorption processes, water purification technologies, and the synthesis of nanoparticles and electrocatalysts are closely integrated. Collaboration across institutions in Arkansas fosters a comprehensive approach to tackling complex water quality challenges facing the state.
