DEVELOPMENT TRENDS OF BIOGAS

subject

description

All over the world, researches are made in order to improve the technologies, the operational and process stability and performance of biogas plants, because the world markets for biogas increased considerably in Europe and all over the world. In this paper we studied the most important parameters related to a biogas plant, starting from the ecologic landfill of Cristian, Sibiu, a landfill which storages industrial and household waste. In this respect, we studied operational parameters, such as organic load and hydraulic retention time, and parameters for evaluation of a biogas plant. Also, we made a case study concerning the evaluation of used waters in the landfill described above under the aspect of pollution sources, way of treatment and evacuation mode of used waters. The existing biomass resources everywhere in the world can give us an idea of the global potential of biogas production, which is not exploited to its capacity, especially in our country.
