Abstract: This study is an attempt for simultaneous removal of sulphates and nitrates from municipal, agricultural and industrial wastewaters by oxidation of the sulphides to sulphates and reduction of the nitrates to nitrogen in electrochemical way. The processes are carried out in newly designed fuel cells and as a result energy is released which can be used. The aim of the work is to improve the energy efficiency of the fuel cell by minimizing internal losses by optimizing the material, design and position of the electrodes.
Keywords: fuel cell, wastewater treatment, oxidation of sulphides, reduction of nitrates
