Practical aspects on electrochemical treatment of urban and domestic wastewater

Electrochemical techniques are suitable for disinfection and purification of civil and domestic wastewaters. The tertiary treatment processes such as advanced oxidation processes and disinfection have been presented at active and nonactive electrode materials. Problems connected to mass transfer limitation in the reactor and possible formation of by-products are discussed. The main issues related to the modeling of the fluid dynamics of the reactor and the kinetics of the reactions involved are examined in order to describe the whole process of pollutant removal and bacteria inactivation during electrochemical disinfection of diluted solutions.
