Control of an anaerobic reactor towards maximum biogas production

Liu, Jing LU ; Olsson, Gustaf LU and Mattiasson, Bo LU (2004) In Water Science and Technology 50(11). p.189-198
Abstract
A new control strategy is introduced for operating anaerobic digestion processes efficiently at high load. The control system includes a cascade controller embedded into a rule-based supervisory system based on extremum-seeking control. The control system measures pH and biogas production rate and varies the organic load by manipulating the influent flow. Good control performances were achieved during the start-up and steady-state running operations and during rejection of disturbances. The control system can run the process under a high load condition and efficiently reject disturbances without explicit measurement of the influent characteristics.
