Abstract: Disclosed is a system and method for treatment of wastewater to destroy organic contaminants using an electrochemical advanced oxidation process. In particular, the method comprises a multistep process, comprising a) generating a concentrated oxidant solution comprising a peroxy oxidant species, such as persulfate or hydrogen peroxide; b) mixing wastewater comprising organic contaminants with the concentrated oxidant solution to provide a mixture comprising wastewater and diluted oxidant, the wastewater and concentrated oxidant solution being mixed in a prescribed ratio to provide a desired concentration ratio of oxidant species to contaminants; and c) in an electrochemical cell comprising a diamond anode, electrolyzing the mixture of wastewater and diluted oxidant, comprising electrochemically activating the peroxy oxidant species for oxidation and destruction of the contaminants. Fast and effective destruction of organic contaminants such as phenol, napthenic acid and other toxic or refractory contaminants is demonstrated at low cost and with reduced usage of added salt.
