The process stability is significantly dependent on controlling the VOA/alkalinity ratio. A physicochemical model was developed to study the interrelation of VOA accumulation with a ratio of VOA/Alkalinity, alkalinity, pH, pCO2, and concentration of un-dissociated HAc. The implemented full-scale biogas plant proved to be economically viable and contributed to sustainable energy production.<eng> Open Access Urheberrechtsschutz 1.0 vorgelegt von Nguyen Van Than GutachterInnen: Wolfgang Pfeiffer (Department of Mechanical/Process and Environmental Engineering, University of Wismar) ; Jens Tränckner (Faculty of Agricultural and Environmental Sciences, University of Rostock) ; Matthias Barjenbruch (Department of Urban Water Management, Technical University of Berlin) Dissertation Universität Rostock 2024 540 620 660 624 333.7 ZI 6800 AR 22500 58.51 58.20 https://purl.uni-rostock.de/rosdok/id00004600 https://doi.org/10.18453/rosdok_id00004600 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00004600-2 https://d-nb.info/1343646782/34 9783860095607 Development of an anaerobic pre-treatment of high strength organic wastewater from the cleaning of tanks of food and fodder road transports--9783860095607--(DE-627)1892172968 urn:nbn:de:gbv:28-rosdok_id00004600-2 doi: 10.18453/rosdok_id00004600 oclc: 1456360613 ppn: (DE-627)1902963946
