Onkal Engin Department of Environmental Engineering, Gebze Institute of Technology, Gebze, 41400, Kocaeli, Turkey Journal Article 2013 03 10 A thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaters<br />was designed as a continuous-flow, completely-mixed homogeneous system. The reactor was operated at ten different organic loading rates ranging from 0.84 g COD/L·d to 7.00 g COD/L·d for a duration of approximately 250 days. The fundamental way to maintain optimum operating conditions of anaerobic digestion systems is to have a well acquaintance with the dynamic behaviours of the process. For this purpose, different types of kinetic models were used in this study, namely the substrate balance, the maximum / specific substrate utilization rate and the methane production rate models. The experimental data obtained indicated that the models used were all applicable for the description of bio-kinetic behaviour of the thermophilic anaerobic contact reactor. https://ijer.ut.ac.ir/article_608_3a89ab587e4f0653bffcea282a9a2452.pdf
