Abstract
An aqueous fluid treatment method and system is provided which preferably uses a 3 step electro-chemical oxidation process to remove organic contaminates from water. A high surface area electro-chemical reaction cell can be employed to remove organic particles and precipitate hardness salts from the aqueous solution. Several 3-phase spark arcs generated mixed oxidants and acoustic cavitations to remove dissolved organic compounds and oxidize organic metal compounds in the next step. Finally, a dielectric discharge in aqueous foam is used to eliminate recalcitrant organic compounds such as, but not limited to, polychlorinated aromatics, disinfectants, pesticides, and pharmaceuticals before release to environment or recycled.
