The application of Fenton-based advanced oxidation processes (AOPs), such as photo-Fenton or electro-Fenton for wastewater treatment have been extensively studied in recent decades due to its high efficiency for the decomposition of persistent organic pollutants. Usually Fenton-based AOPs are used for the degradation of targeted pollutant or group of pollutants, which often leads to the formation of toxic by-products possessing a potential environmental risk. In this work, we have collected and reviewed recent findings regarding the feasibility of Fenton-based AOPs (photo-Fenton, UVC/H2O2, electro-Fenton and galvanic Fenton) for the detoxification of real municipal and industrial wastewaters. More specifically, operational conditions, relevance and suitability of different bioassays for the toxicity assessment of various wastewater types, cost estimation, all of which compose current challenges for the application of these AOPs for real wastewater detoxification are discussed.

Using Data

AbstractTwo published criteria for analyzing and optimizing Advanced Oxidation Processes are compared with respect to their usefulness for process optimization and for determination of the most cost-effective of several candidate processes for a particular application. The Cumulative Efficiency (CE) method compares the amount of target contaminant removed per amount of oxidant used. The Electrical Energy per Mass (EE/M) method compares electrical energy required per kilogram of target pollutant removed. The methods were evaluated using data from treatability studies for DOC removal from a ground water contaminated with 50 mg/L of organic carbon, using processes consisting of combinations of ozone, hydrogen peroxide, and ultraviolet light. It was found that the CE method gave better information about how to manipulate the chemistry for optimization, while the EE/M method provided clearer guidance for process selection on economic grounds, making the methods complimentary in treatability studies. The CE method also predicted that a tandem process might function more efficiently than either of the component single processes, which was found experimentally to be the case.

Electrochemical Technology

<p>Many human activities result in the production of wastewater. Usually, physical, chemical and biological processes are successfully combined for the treatment of municipal wastewater, attaining good removal efficiencies. However, some industrial processes introduce anthropogenic recalcitrant pollutants in wastewater that are quite difficult to remove or degrade using conventional means and that should be removed due to their hazardousness. In such cases, the application of an Advanced Oxidation Processes (AOP) uses to be a good and/or promising alternative to attain an appropriate effluent. These processes rely on generating hydroxyl radical, which is a powerful oxidant that mineralizes efficiently pollutants contained in wastewater. In this review, we focus on the use of electrochemical methods to produce hydroxyl radical, using directly or indirectly electrochemical technology, within the so-called Advanced Electrochemical Oxidation Processes (EAOP). These processes include electrochemical, sonoelectrochemical and photoelectrochemical technologies and this work describes the fundamentals, main cases studied in the literature related to actual industrial waste treatment and tries to help in the elucidation of the range of applicability of each technology.</p>
