Abstract:
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 apparatus including a substantially self-contained housing or container which is adapted to receive components including 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, and/or receive, contain and/or circulate fluid or aqueous solution.
Abstract:
A system and method for removing fouling from a photoelectrocatalytic oxidation assembly is provided. The method includes resetting a first counter, increasing the first counter by a first channel increment value, and determining if the value in the first counter exceeds a value corresponding to the number of channels provided in the assembly. If the first counter does not exceed the number of channels, the polarity in a channel associated with the value in the first counter is reversed, and a first timer is reset. If an amount of time in the first timer does not exceed a first time period, the first timer is increased by a first time increment until the time remaining in the first timer exceeds the first time period and the polarity reversal is terminated, returning to the step of increasing the first counter by a first channel increment value.
Abstract:
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 an apparatus comprising spaced-apart electrode structural support members extending from a first sidewall to a second sidewall, the spaced-apart electrode structural support members each having at least one photoelectrode and counterelectrode coupled to respective terminals adapted to be electrically coupled to a power supply, and at least one ultraviolet light source between the spaced-apart electrode support members.
Abstract:
A system and method for operating a photoelectrocatalytic oxidation assembly for removing fouling from components is provided. The method includes the steps of resetting a first counter, increasing the first counter by a first channel increment value, and determining if the value in the first counter exceeds a value corresponding to the number of channels provided in the photoelectrocatalytic oxidation assembly. If the first counter does not exceed a value corresponding to the number of channels provided in the photoelectrocatalytic oxidation assembly, the following steps are performed: reversing polarity in a channel associated with the value in the first counter, resetting a first timer, determining if an amount of time in the first timer exceeds a first time period, increasing the amount of time remaining in the first timer by a first time increment if the amount of time remaining in the first timer does not exceed the first time period, terminating the polarity reversal in the channel associated with the value in the first counter when the time remaining in the first timer exceeds the first time period, and returning to the step of increasing the first counter by a first channel increment value. If the first counter does exceed a value corresponding to the number of channels provided in the photoelectrocatalytic oxidation assembly, the step of returning to the step of resetting the first counter is performed.
