Non-thermal Liquid Plasma Treatment for Removal of Antibiotics in Wastewater
Additional Funding Sources
The project described was supported by the SummerUndergraduate Research Fellowship program through the University of Idaho’s Office of Undergraduate Research.
Abstract
Traditional wastewater treatment processes are not able to degrade pharmaceuticals which find their way into the water system. One solution currently being explored to prevent these emerging contaminants from release into the environment is non-thermal liquid plasma (NTLP) treatment, a type of advanced oxidation process which produces high energy mobile electrons and oxidizing radicals to degrade large organic molecules. In this proposed project, a novel reactor design is used, which includes a circulating treatment and discharge occurring in the liquid phase to remove three types of beta-lactam penicillins. Spectrophotometry is used to measure the concentrations of the antibiotic solution according to their respective methods. The results of this study show the amount of degradation achieved, the effects of different reactor parameters on removal rates and efficiency, energy yield (mass removed per kWhr), and the influence of -OH and H2O2 radicals on removal.
