Dielectric barrier discharge fluid purification system

A method for purification of contaminated fluid by use of non-thermal plasma produced by dielectric gas phase corona discharge, said method comprising:

• providing a housing formed with a fluid inlet and a fluid outlet, a corona discharge reactor means arranged in said housing for passage of the contaminated fluids therethrough, said reactor means comprising upper and lower frame elements and a plurality of spaced-apart oppositely charged electrodes being supported by said frame elements, arranged as a plurality of adjoining triangular modules, each of said electrodes having a conducting element surrounded by an insulating jacket, said plurality of electrodes being arranged perpendicular to said frame elements in rows of alternate polarity wherein spacing between said electrode rows of alternate polarity is less than or equal to a diameter of said electrodes, and a fluid swiveling means in fluid communication with said corona discharge reactor for creating and directing a turbulent flow of said fluid through said reactor;
• connecting an electrical power supply to said electrodes, such that a substantially uniformly distributed plurality of electrical microdischarges is produced;
• and
• introducing the fluid into said fluid inlet,
• such that said electrical microdischarges react with constituents of said fluid to produce activated radicals, while said fluid swiveling means provides high exposure of said fluid to said electrical microdischarges, such that contaminants contained in the fluid are attacked and decomposed by said radicals.
