The invention relates to a water-processing electrochemical reactor. The invention relates also to a process for the treatment of water in a water-processing electrochemical reactor. More precisely, the present invention describes a water-processing apparatus conveniently shaped/devised to promote a set of electrochemical advanced oxidation processes (EAOPs) based on in-situ H2O2 electrogeneration and, preferably, to be applied to the treatment of water and wastewater containing organic (or microbiological) contaminants by electro-Fenton (EF), photoelectro-Fenton (PEF) and solar photoelectro-Fenton (SPEF) processes.
