Urban wastewater effluents are attracting great interest due to the potential applications of reclaimed wastewaters in agriculture or industry sectors. In the treatment of this type of effluents, a disinfection stage is always required to obtain a high quality effluent. In literature, it has been described the elimination of microorganisms (E. coli) by the addition of chemical reagents such as ozone, hydrogen peroxide or chlorine derivate products. In this context, electrochemical oxidation emerges as a good alternative to carry out the on-site generation of disinfectant agents from the species naturally contained in wastewater. This production of can be attained by anodic and/or cathodic processes using different electrode materials. With this background, this lecture aims to describe results obtained in the disinfection of actual effluents of municipal WWTP using single and irradiated electrolytic technologies, comparing the efficiency and main advantages of drawback of each technology assessed.
