Abstract
This paper presents a technique for configuring wastewater process sim ulations so that the hydraulic characteristics are similar to the real plant Residence time distribution (RTD) tests are performed on two bi ological nutrient removal pilot plants. The RTD tests proved valuable for evaluating mixing effectiveness, volume utilisation and for determ ining an appropriate hydraulic topology for the dynamic models of the pilot plants. As a result of this work, simulation execution times bec ame much faster due to a significant reduction in the number of effect ive stirred tanks required in the model. The work also identified shor t circuiting and dead zones in the pilot plants. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
