Written by experts in the field, this thoroughly updated third edition covers commonly used
and emerging suspended and attached growth reactors. Drawing on their extensive …

Simultaneous biological nutrient removal (SBNR) is the occurrence of biological nutrient
removal (BNR) in systems that do not possess defined anaerobic and/or anoxic zones. A …

Computational Fluid Dynamics (CFD) was used to simulate the mixing characteristics of four
different circular anaerobic digester tanks (diameters of 13.7, 21.3, 30.5, and 33.5 m) …

Anaerobic digester is the most widespread technology for the treatment of biomass to
produce biogas. Mixing is an important parameter to have a highly efficient anaerobic …

This study presents a computational fluid dynamics (CFD) model of an aerated wastewater
treatment oxidation ditch, taking into account gas-liquid flow, oxygen mass transfer and …

The operating condition of an oxidation ditch (OD) has significant impact on energy
consumption and effluent quality of wastewater treatment plants (WWTPs). An …

Oxidation ditches (ODs) are often used for wastewater treatment. However, limitations of
ODs like high energy expenditure and increased sludge sedimentation hinder its wide …

Experimental and numerical studies were carried out to determine the full-scale Oxidation
Ditch (OD) hydrodynamics considering various turbulence models. Firstly, the experimental …

Though hydrodynamic characteristic is an important parameter for the optimization of
reactors, very little research deals with the hydrodynamics of oxidation ditches. This paper …

The modern age of wastewater treatment modelling began with publication of the
International Water Association (IWA) Activated Sludge Model (ASM) No. 1 and has …
