Abstract: Two kinetic inhibition models were considered in concert with mass transport equations in biofilm to demonstrate how these phenomena interact, and explain, in principle, why fixed‐film processes may be more stable than ...

Abstract: The characterization of sediment transport is an important problem that has been actively studied for some time. Numerous approaches have been demonstrated in the literature, including mechanistic models, probabilistic ...

Abstract: Fixed‐film nitrification was studied in a pilot‐scale fluidized bed treating municipal secondary effluent. A mechanistic mathematical model incorporating reaction stoichiometry, diffusion, multisubstrate kinetics with ...

Abstract: The calculation of reaction rates in biofilm shells is needed for the design of biological fixed-film reactors. Most biological reactions are nonlinear and require a numerical solution of the material balance equations. ...

Abstract: This study investigated the effectiveness of magnetite as ballast material through a technology called BioMag in nitrogen and phosphorus removal and in processing peak flows at a wastewater treatment plant using data from ...

Abstract: It is suggested in this paper that recalcitrant organopollutants can be degraded efficiently by a hemoglobin-catalytic reaction in the presence of hydrogen peroxide (i.e.,

Abstract: Kinetics of an abiotic method for oxidative pentachlorophenol (PCP) degradation in soil under unsaturated conditions and a neutral pH has been studied. Reagents used were heme as the catalyst and peroxide as the oxidant. ...

Abstract: The environmental impact of pentachlorophenol (PCP) has been the subject of extensive research in recent years. Investigations of PCP degradation using both biotic and abiotic methods are extensively reported in literature. ...
