Abstract

WWTP upgrading at any price? A new dynamic simulation concept evaluates the effects of separate reject water treatment J. Mihopulos DHV Water BV, Hafnersteige 39, D-75305 Neuenbuerg, Germany ABSTRACT Wastewater treatment facilities are dynamic. The combined effects of changes in influent flow, waste composition, treatment unit processes, and operational modifications result in complex dynamic behavior that can be difficult to understand and, therefore, difficult to control and optimize. Current trends toward more advanced treatment processes, such as separate process water treatment, biofilm processes, etc., where biological nutrient removal is aimed, are increasing plant complexity and prompting a growing number of engineers to rely on dynamic models and computer-based decision support tools when deciding how best to improve plant design or operation. The paper describes the results of systematic investigations through dynamic simulation concerning process water treatmen
