Determination of readily biodegradable cod (Ss) in domestic wastewater

At present, there is a lot of interest in the use of dynamic simulation for optimization and operation of wastewater treatment plants. For this purpose, different mathematical models are used. Development of these models requires a complicated conceptual approach. It involves identification of all carbonaceous and nitrogenous components. The Activated Sludge Model No.1 (ASM1) presented by the IAWQ Task Group on Mathematical Modelling for Design and Operation of Biological Wastewater Treatment Processes is generally accepted as state-of-the-art and is used for simulation of wastewater treatment plants in many studies. In this study, oxygen uptake rate (OUR) measurements with domestic wastewater were carried out in batch reactors for the estimation of readily biodegradable COD (Ss) fraction involved in ASM1. © 2006.
