1. A method for removing a pharmaceutical from a waste stream, comprising:

  • submersing two electrodes in the waste stream, the waste stream comprising a water component and the pharmaceutical, the electrodes bordering an interaction zone extending therebetween;

    applying a pulsed electrical signal to at least one of the electrodes thereby generating oxyhydrogen gas from the water component,the oxyhydrogen gas forming bubbles in the interaction zone that rise to a surface of the waste stream, wherein at least some of the bubbles contact the pharmaceutical as they rise through the waste stream;

    oxidizing the pharmaceutical with an oxidant contained in the oxyhydrogen gas; and

    transporting at least a portion of the treated pharmaceutical to the surface of the waste stream with the bubbles that contact the pharmaceutical.
