A new method to determine the microbial kinetic parameters in biological air filters

Kinetics of styrene biodegradation in synthetic wastewaters using an industrial activated sludge

“…The most commonly employed kinetic model for biodegradation of substances, which above a certain concentration inhibit microbial growth, is the Haldane kinetic model. This model has been successfully used to fit the data for biodegradation of some aromatic pollutants such as phenol, 4-chlorophenol, benzene, toluene and xylene by pure, as well as mixed, bacterial populations in activated sludge [11][12][13][14][15][16]. However, the validity of the Haldane kinetic model has been found to depend on the concentration range of the toxic compound employed; for example, Nuhoglu and Yalcin [17] have managed to fit the Haldane model to phenol biodegradation data by a mixed bacterial population derived from an activated sludge only for phenol concentrations <100 mg/l.…”

Investigating the kinetics of autotrophic denitrification with thiosulfate: Modeling the denitritation mechanisms and the effect of the acclimation of SO-NR cultures to nitrite

“…Some authors have used single-substrate kinetic models taking into account microbial growth rates associated only to a single pollutant biodegradation (Monod, Haldane and other kinetic equations) [11][12] to describe biological processes. A drawback of single-substrate kinetic models is the disability to describe the potential limitations of other species such as nutrients or the electron acceptor.…”

Function and limits of biofilters for the removal of methane in exhaust gases from the pig industry

“…The EBRT depends on the biofilter volume and air flow rate (Delhoménie et al 2008). Due to the low solubility of CH 4 in water of 0.022 g L −1 at 20°C, the EBRT is an important factor for the performance of a biofilter treating CH 4 from the pig industry (Girard et al 2009).…”
