Knowledge of activated sludge biokinetic parameters is important to simulate the behaviour of an activated sludge plant with the commonly used IAWQ models (e.g. Henze et al., 1987). Batch experiments using pulse substrate additions in a small bioreactor are often applied to collect data about activated sludge behaviour. However, many of the experiments that were designed in the past suffer from...

A systematic model calibration procedure for the Activated Sludge Model No. 1 (ASM1) was presented and evaluated on a combined municipal-industrial WWTP. A careful definition of the purpose of the model determines how to approach the model calibration. It was illustrated how additional information obtained from tests specifically designed to describe the hydraulics and the biology of the system...

The electrochemical corrosion rate of magnesium depends on the stability surface layer formed. Based Mg substrate, oxide structure comprises a dense MgO/Mg(OH)2 mixture underneath porous plate-like Mg(OH)2 layer. While kinetics anodic partial reaction have been mainly attributed to MgO, recent studies showed an effect thickness cathodic reaction. A thinner has associated with higher oxygen redu...

During the optimization of environmental biotechnology processes, it is important to count on proper and reliable information about kinetic stoichiometric parameters microorganisms. In this work, biological sulfide oxidation process was assessed under two novel dynamic pulse respirometric approaches: in-situ respirometry conducted in airlift bioreactor ex-situ carried out microreactors (microre...
