Abstract: A depuration process is employed for removing off-flavor contaminants from fish through an advanced oxidation process. Before the fish is harvested, the fish is transferred to a depuration tank or zone containing water. Off-flavor compounds leach from the tissue of the fish into the water in the depuration tank or zone. The water in the depuration tank or zone is circulated through an advanced oxidation reactor that, through an oxidation process, reduces the concentration of the off-flavor contaminants in the water.

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 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.
