## Abstract

A water container or bottle with integrated disinfection preferably includes a battery compartment, a control printed circuit board (PCB) to manage several parameters including timing, voltage rate, and user-interface. A high voltage power supply is coupled to a set of electrodes to cause an electric discharge. The electric discharge results in a series of reactions in the water that eliminate bacteria and viruses, dissolves organic material, and oxidizes inorganic compounds.
