Abstract. In this paper, the problem was to carry out a study on the process of mass production of biogas and to deduce the analysis of an example implemented in the wastewater treatment plant. The main problem is the correct processing of the activated sludge and the extraction of the biogas with its basic components. The method described in the paper is current as a technology in the biogas production industry by treating activated sludge from a wastewater treatment plant. For the extraction of biogas according to EU standards and the possibility to use it at each stage of extraction, methods and technologies specific to this process are used and explained.
Keywords: biogas, desulphurization, gas flare, co-generation unit, PLC, SCADA, automatic control.
