Wastewater Treatment Technologies

Research in wastewater treatment technologies focuses on developing and improving methods for purifying water contaminated by industrial, agricultural, and municipal sources. This work involves investigating novel materials for filtration and adsorption, exploring biological and chemical degradation processes for pollutants, and designing systems for nutrient recovery and water reuse. Specific areas of inquiry include the efficacy of advanced oxidation processes, the performance of membrane technologies under various conditions, and the application of nanomaterials for contaminant removal. Research also addresses the characterization of complex wastewater matrices and the development of cost-effective and energy-efficient treatment solutions.

This research holds particular relevance for Arkansas, a state with significant agricultural and industrial sectors that generate substantial wastewater streams. Improving treatment technologies can protect the state's vital water resources, including rivers and the Delta aquifer, which are critical for agriculture, industry, and public health. Furthermore, advancements in nutrient recovery from wastewater can support sustainable agricultural practices by providing valuable fertilizer inputs, aligning with the state's economic base and environmental stewardship goals. The development of robust and affordable treatment systems is essential for both existing infrastructure and future growth across Arkansas.

This field draws upon expertise in materials science, membrane separation, and environmental impact assessment. Investigations into molecular biology inform the understanding of microbial processes in biological treatment systems. The research also connects to life cycle assessment for evaluating the overall sustainability of treatment technologies and to biofuel production through the valorization of wastewater byproducts.
