摘要

The bioenergetical stimulation technologies which have been largely developed for the past years can be used for bioremediation of waste and wastewaters in sense of stimulating the microbial decay of various pollutants and recover useful products but generate energy as well. In anaerobic fermentative processes to produce biogas, further research are required in order to produce higher methane content biogas but also to decrease the hydraulic retention time of the organic substrate in bioreactor. This paper aims to point out that the dielectric properties of the organic materials to be used for biogas production could provide valuable indications related to the biochemical processes in anaerobic digesters. The experimental results shown that by assessment of some typical parameters such as the electric permittivity, the electric capacity and the dielectric loss factor in laboratory-scale experiments we can improve the methanogens activity and consequently the quality of biogas but also the efficiency of the biogas plants in industrial applications.
