Evaluation of Biodegradation Kinetics Models for Microconstituents Under Typical Sewage Treatment Conditions
Abstract:Mathematical models developed for design and operation of biological wastewater treatment such as those from the International Water Association (IWA) were not concerned with specific chemical compounds. Consequently commercial modeling software for microconstituents (MCs) removal have been developed, but models used in these packages have not incorporated developments in IWA models which present numerous possibilities that have not been evaluated. This paper discusses many theoretical models that could be applicable considering coupling with activated sludge (AS) models developed by the IWA. The literature was reviewed for the kinetic models that can be used to describe transformation of MCs (volatilization and photodegradation were considered negligible) in an AS process. It is recommended that sorption models should depend on total concentration of solids in AS and biodegradation studies should incorporate active mass and not mixed liquor suspended solids concentration (MLSS) in their kinetic formulations.
