APPARATUS AND METHOD FOR TREATING AQUEOUS SOLUTIONS AND CONTAMINANTS THEREIN

摘要

The present disclosure is generally directed to devices and methods of treating aqueous solutions to help remove or otherwise reduce levels, concentrations or amounts of one or more contaminants. The present disclosure relates to a method of which includes the application of a constant current or a pulse width modulation duty cycle to at least one counterelectrode (e.g. cathode) and at least one photoelectrode (e.g. anode) provided or arranged around at least one UV light source in a housing adapted to also receive, contain and/or circulate fluid or aqueous solution.

1. A method for removing or reducing the level of contaminants in a solution, the method comprising:
providing a solution into a cavity of a device, wherein the cavity of the device houses a light tube, a photoelectrode provided around the light tube, the photoelectrode comprising a primarily titanium foil support with nanotubes of titanium dioxide provided thereon, a counterelectrode provided in the space between the photoelectrode and a cavity wall of the device; irradiating the photoelectrode with ultraviolet light; and flowing a first constant current through a first terminal coupled to the photoelectrode and a second terminal coupled to the counterelectrode.
