Pulsed Streamer Reactor Characterization. Phase II
Abstract
Aqueous phase pulsed corona discharge is considered an alternative for wastewater treatment. This report presents an analysis of the physical and chemical aspects of corona discharge in water, in salt solutions, and in solutions containing added particles. The addition of activated carbon to liquid phase corona discharges leads to enhanced streamer production and higher sparkover voltages. Higher sparkover voltages and enhanced streamer production are expected to lead to enhanced production of reactive species that lead to pollutant degradation. A mathematical model describing bulk solution chemical reactions, chemical reactions in the particle phase, and diffusion into the particle phase, has been developed using the methods of spatial averaging. Measurement of phenol degradation and byproduct formation in the liquid phase corona reactor with and without added particles and at various applied voltages was performed. Experiments with corona in the presence of aqueous film-forming foam (AFFF) indicate that corona is able to mechanically disrupt the structure of the foam and that a corona discharge can be created in the presence of a foam. Foamability measurements indicate however, that the pulsed corona may not significantly chemically degrade the AFFF.
