<abstract>Wastewater treatment plants (WWTP) are needed to treat municipal wastewater to reduce the impact of pollutants on the environment and the ambient nature. The discharge of treated wastewater and the disposal of sludge from treatment plants t...
The increased importance of wastewater treatment has led to development of mathematical models for optimization and design of wastewater treatment plants. WWTP modelling entails the modelling of the biological reactions (biokinetics) and underlying f...
In this thesis, it is hypothesised and confirmed that the bioreactors are not at all completely mixed and, hence, current models wrongfully calibrate the kinetic parameters by correcting for the errors induced by the over-simplified modelling of mixi...
The thesis comprises of four parts. The first part provides the detailed account of CFD (computational fluid dynamics) modelling of WWTPs. Second part is about integration of CFD hydrodynamic models with the biokinetic models to evaluate the impact o...
In the first part, detailed CFD hydrodynamic modelling of a bioreactor of Eindhoven WWTP is performed. The impact of reactor configuration and process conditions on gas dispersion is observed. Potential regions of poor mixing are identified. The diff...
In the second part, the CFD hydrodynamic model of Eindhoven WWTP is extended by integrating it with bio-kinetic models, firstly with ASM1 and secondly with ASMG1. The impact of local mixing conditions on the dissolved oxygen (DO) and ammonium concent...
In the third part, the compartmental modelling (CM) was setup based on the DO concentrations using CFD-biokinetic model. A novel idea of cumulative species distribution (CSDs) to quantify the variations is introduced here as well. The CSDs serve as a...
In the last part, the impact of mixing on a CSTR based model calibration is shown. It is shown that the TIS models predict different estimated values under different mixing conditions. Therefore, it is important to take into account the mixing condit...
It is concluded that this thesis has demonstrated the ability of CFD-biokinetic modelling to evaluate the process more accurately. Tthe derivation of a compartmental model has also provided the solution of high computational demands, commonly attribu...
