Abstract
Methods and systems for treating a waste stream (202) in a waste treatment system (204) involve performing a unit process (206) by contacting the waste stream (202) with oxyhydrogen-rich gas (214) generated on-site by an oxyhydrogen gas generator (207). The gas generator (207) preferably involves applying a pulsed electrical signal to a series of closely-spaced electrodes that are submerged in the waste stream (202) to dissociate a water component of the waste stream (202), thereby producing oxyhydrogen-rich gas (214, 220) . Operation of the gas generator (207) in the waste stream (202) may accomplis h one or more unit processes (206) for waste treatment, such as conditioning, stabilization, thickening, and dewatering, among others. At least a portion of the oxyhydrogen-rich gas (220) can be conveyed for a second use (222) in the waste treatment system, such as a source of combustible fuel for incineratio n or power generation, for example.
