THE PROBLEM
Fermentation of organic residues in municipal wastewater treatment plants has been increasingly implemented in recent years. In anaerobic digesters, there is frequently available space which can be used for the co-digestion of organic residues. This additional input of biomass leads to an increased energy yield. Due to the addition of biogenic residues as co-substrate in the anaerobic digester, impurities such as glass, sand, and metal particles are added to the treatment process. These impurities lead to increased costs, increased wear of the plant components, disturbances in the process, and to a loss of digestion volume.
