Patent ID: 11124431

Abstract:
A water treatment system includes an adsorption column including granular activated carbon (GAC) that adsorbs contaminants from untreated water onto the GAC, thereby producing treated water, a first electrode disposed at a proximal side of the adsorption column, with a gap between the first electrode and the GAC, a second electrode disposed at a distal side of the adsorption column, a drain outlet in fluid communication with the adsorption column for draining water out of the adsorption column, a gas inlet in fluid communication with the adsorption column for injecting a displacement gas into the adsorption column, a high voltage power supply electrically connected to one of the first electrode and the second electrode for generating a plasma discharge within the GAC, thereby regenerating the GAC within the adsorption column, and a gas outlet in fluid communication with the adsorption column for venting waste gas produced by the plasma discharge.
