System and method for treating aqueous solutions and contaminants therein

A system for removing or reducing the level of contaminants in a solution comprising:

• a pump, a tank, and a carbon filter in fluid communication with a photoelectrocatalytic oxidation device;
• wherein the photoelectrocatalytic oxidation device comprises:
• a housing having a first end opposing a second and at least partially defining a cavity having a cavity wall and a cavity length;
• a light tube provided within the cavity and adapted to help disburse or otherwise provide ultraviolet radiation over most of the cavity length;
• a photoelectrode provided around the light tube, such that a portion of the light tube is received by the photoelectrode;
• a separator provided around the photoelectrode, such that a portion of the photoelectrode is received by the separator;
• and
• a counterelectrode provided around the separator, such that a portion of the separator is received by the counterelectrode;
• wherein the photoelectrode comprises a primarily titanium foil support with a layer of titanium dioxide provided on at least one surface of the photoelectrode;
• and
• wherein the photoelectrode and counterelectrode are each coupled to a respective terminal adapted to be electrically coupled to a power supply.

A system for reducing the level of contaminants in a solution comprising:

• a pump, a tank, and a carbon filter in fluid communication with a photoelectrocatalytic oxidation device, the device comprising:
• a housing defining a cavity, the cavity having a first cavity end opposing a second cavity end;
• a light tube containing an ultraviolet light source provided in the cavity between the first and second cavity ends;
• a photoelectrode provided in the cavity between the first and second cavity ends, the photoelectrode receives the light tube such that the photoelectrode substantially surrounds the light tube;
• and
• a counterelectrode provided in the cavity between the first and second cavity ends, the counterelectrode receives the photoelectrode such that the counterelectrode substantially surrounds the photoelectrode and light tube;
• and a means for preventing electrical short preventing between the photoelectrode and counterelectrode.
