Abstract
A control system with the objective of improving nitrogen removal has been installed in a 60,000 p.e. communal wastewater treatment plant. T he system controls the biological stage of the activated sludge plant employing mass balances for evaluating the control measures. The contr ol resulted in an overall reduction of the nitrogen output by half and one third in warm and cold periods respectively, compared to an uncon trolled reference train. Violating effluent standards could be avoided through the application of the control system. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
