Treatment of a waste stream through production and utilization of oxyhydrogen gas
First Claim
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.

Abstract
Methods and systems for reducing a redox active contaminant in a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting redox active contaminant in the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. The oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as oxidation, stripping, floatation, disinfection, conditioning, stabilization, thickening, and dewatering, among others.
