INFLUENCE OF ELECTRICAL CONDUCTIVITY AND TEMPERATURE IN A MICROBIAL FUEL CELL FOR TREATMENT OF MINING WASTE WATER

Abstract

The influence of electrical conductivity and temperature on the efficiency of MFC with a basic microbial process in the anode zone - microbial sulphate reduction has been determined. A technological scheme of a laboratory installation has been synthesized allowing permanent control and management of basic process parameters - pH, electrical conductivity, temperature and OCV. The studies have been carried out at the optimal values of OCV, power density and current density for four different conductivity values and temperature under abiotic conditions in the anode zone of the fuel element and a comparison has been made with the biological process of the microbial sulphate reduction. On the basis of LabViewR has been offered a possibility of measuring different electrochemical parameters of the MFC that determine its efficiency. The results obtained will be used to optimize the work of MFC based on the microbial sulphate reduction process to treat wastewaters with high content of sulphates.
