Boron-doped diamond electrodes prove to be a highly appropriate electrode in terms of oxidation power, application and stability. Full scale electrolysis cells for industrial applications equipped with a maximum BDD-electrode area of 3,6 m² were constructed and installed. With this electrode configuration the purification of a variety of industrial wastewaters was successful. Several full scale electrolysis cells were installed at customers site and demonstrate that the electrochemical wastewater treatment is a highly reliable technology for manifold industries.
