Proposals for the Modernization of Biogas Plants so as to Build Their Profitability

EasyChair Preprint no. 2102

Abstract

In the digester, it is necessary to organize periodic mixing of the substrate, which ensures the effective and stable operation of the BSU. The purpose of mixing is the release of biogas formed, mixing of fresh substrate and bacteria (grafting), preventing the formation of rust and sediment, preventing the formation of areas of different temperatures inside the digester, ensuring uniform distribution of the bacterial population, preventing the formation of voids and clusters that reduce the effective area of the digester. When choosing a mixing method, it should be taken into account that the fermentation process is a vital process of the symbiosis of various bacterial strains, and if this community is destroyed, the fermentation process will be unproductive until a new bacterial community is formed. Therefore, too frequent or prolonged mixing is harmful. Slow mixing of the substrate every 4-6 hours is recommended. Optimal mixing of the feed increases biogas yield by up to 50%. A comparative analysis of the types of costs associated with the construction of the biogas plant will be carried out on the digesters of these biogas plants and facilities and equipment (devices) directly associated with them.
