Project Title:

Cold Plasma treatment of waste water

Project Coordinator:

Dr PJ Cullen

Project Abstract

This project will design, build and validate an innovative rapid effluent treatment solution for the food and agri sectors. The project will utilise the afterglow (unique reactive species) created during cold plasma discharge to treat process effluent waters from vegative and animal sources. A novel high voltage dielectric discharge barrier will be optimised to maximise the generated reactive oxygen species and diffused immediately within the effluent. The efficacy of the system will be assessed and optimised for reduction of Biological Oxygen Demand (BOD) as well as chemical degradation and pathogen inactivation. Plasma diagnostics, including optical emmission and absorption spectroscopy will be employed to characterise the reactive species generated and correlated to the effluent degradation characteristics in order to elucidate mechanisms. The project involves the development of an innovative solution and validation trials under reallife conditions. The proposal is based upon preliminary work at the DIT Bio-Plasma group and brings together expertise in plasma physics, process engineering, chemistry and microbiology with industry input to provide an environmentally friendly solution for food processing effluent treatment.
