The Virtual Chief Operator – a fuzzy-based process control strategy for optimising anaerobic effluent plants
Due to rising effluent charges and tougher environmental protection requirements, many brewery and food plants operate their own treatment plants. In order to lower cost-impacting COD values and to largely avoid production of sewage sludge, many operations go for anaerobic treatment. Biogas arising can be used on site, the plant pays for itself sooner. Taking Karlsberg Brauerei as an example, this paper describes a novel process control that identifies and heads off critical situations using fuzzy logic.
