Abstract
A procedure was developed to manipulate the aerobic nitrification volu me by means of model based respirometry. The objective was to oxidise all ammonia nitrogen. The required aerobic volume was calculated from the influent flow rate, the influent concentration nitrifiable nitroge n and maximum ammonia oxidation rate which were obtained from respirom etric batch-experiments using model calibration and state estimation t echniques. Automation of the procedure resulted in the development of the RESCUE (REspirometric activated Sludge and wastewater Characterisa tion Unit). The procedure was tested for a pilot scale plug-flow activ ated sludge plant with satisfactory results. (C) 1998 Published by Els evier Science Ltd. All rights reserved.
