Abstract
In this paper, a tabu search approach for optimizing operating conditions of anaerobic digester is proposed. Biogas production attracts field’s interests due to the regulations in treating sewages and energy consumptions. Many researches have been conducted to find better operating conditions; however, they are limited to laboratory sized and specific inputted anaerobic digester. Anaerobic digestion model No. 1 (ADM1) is used to break those limitations. In modeling, a specific digester concerned is able to be characterized by modifying its setting constant - kinetic parameters and stoichiometric coefficient. Repetitive experiments by changing operating conditions are possible without any risk and burden. Tabu Search, a neighbor search meta-heuristic, is considered to find the optimal operating conditions. It prevents from converging into a local optimal solution with the management of tabu list. A full-scale anaerobic digester, Jungnang (J3) located in Seoul, South Korea, is modeled and the optimal operating condition for J3 is calculated with use of model to measure the performance of proposed algorithm.
