Electrochemical technologies for wastewater treatment at pilot plant scale

Process scale-up is a critical, but essential, step in the development of real electrochemical system for oxidation of organic compound. This mini review wants critically analyze the research efforts carried out in the last years about pre-pilot and pilot scale plants, to support the implementation of such technologies in industrial environmental. In the first section are presented the potentiality and the issues related to the anodic oxidation. The second part is dedicated to the electro-Fenton process, while the last is focused on the coupling of the two previous methods. The analysis highlights key factors which are involved in the scaling-up, which are concerning not only the plant size, but involved also their efficiency and economic feasibility.
