Abstract: The activation of the C—H bond using low temperature plasma with an inlet liquid stream such that value added products are formed effectively. An organic liquid (e.g., hexane which is immiscible with liquid water) is injected into a flowing gas (argon) stream followed by mixing with a liquid water stream. Thereafter, the mixture contacts a plasma region formed by a pulsed electric discharge. The plasma formed with the flowing liquid and gas between the two electrodes causes chemical reactions that generate various compounds.

A plasma discharge is propagated along the flowing liquid film region. Water is dissociated and reactive species such as hydroxyl radicals, hydrogen peroxide and nitrogen oxides are formed. The organic compound reacts with the reactive species such as hydroxyl radicals and hydrogen peroxide present in the flowing liquid film region and in the flowing gas stream to produce organic compound dissociation products. At least some organic compound dissociation products and nitrogen oxides are transferred to a bioreactor for further degradation of organic compounds. The nitrogen oxides are used as nutrients for bacteria in the bioreactor. Feedback control of the plasma reactor is based on conditions detected and determined in the biological reactor.

Abstract: Novel accelerated methods involving corona discharge, and preferably pulsed streamer high voltage corona discharge, in combination with an effective amount of suitable particles to break down organic contaminants, such as phenol and phenol red, in aqueous mediums are disclosed. More particularly, it has been discovered that the addition of an effective amount of suitable particles to the aqueous phase of a corona reactor greatly affects the properties of the corona discharge, i.e., streamer length, intensity, number of streamers and sparkover voltage, thereby significantly increasing the breakdown voltage (i.e., the maximum voltage prior to sparkover), so that the removal of organic contaminants may be accelerated, since the production of hydroxyl radicals, aqueous electrons and hydrogen peroxide increases with increases in the applied discharge voltage.

Abstract: A method for oxidizing an organic contaminant in an aqueous medium generates H2O2 in the aqueous medium through the use of a corona discharge procedure. A quantity of hydroxyl radicals is generated from the H2O2. An organic contaminant is oxidized in the aqueous medium by reacting the hydroxyl radicals with the organic contaminant, the oxidation being enhanced by methods for facilitating the generation of hydroxyl radicals.
