By critically evaluating previous models, a new mechanistic model is developed to describe simultaneous storage and growth processes occurring in activated sludge systems under aerobic conditions.… Expand
Respirometric estimation of the oxygen affinity constants for biological ammonium and nitrite oxidation
The nitrification process (ie biological ammonium oxidation to nitrate) is a two-step process with nitrite as an intermediate product. As it is an aerobic process, its kinetics is highly dependent on… Expand
Inorganic carbon limitations on nitrification: experimental assessment and modelling.
Nitrification is a two-step process that involves two different biomass populations: ammonia oxidising biomass (AOB) and nitrite oxidising biomass (NOB). Both populations are autotrophic (i.e. their… Expand
Start-up of a nitrification system with automatic control to treat highly concentrated ammonium wastewater : Experimental results and modeling
The start-up of a biological nitrifying system to treat high-strength ammonium wastewater must be done carefully to avoid ammonium or nitrite build-up and subsequent system destabilization due to… Expand

An enhanced biological phosphorus removal (EBPR) system was developed in a sequencing batch reactor (SBR) using propionate as the sole carbon source. The microbial community was followed using… Expand
Total and stable washout of nitrite oxidizing bacteria from a nitrifying continuous activated sludge system using automatic control based on Oxygen Uptake Rate measurements.
Partial nitrification (ammonium oxidation to nitrite) has gained a lot of interest among researchers in the last years because of its advantages with respect to complete nitrification (ammonium… Expand
Biological nitrogen removal of high-strength ammonium industrial wastewater with two-sludge system.
The biological nitrogen removal (BNR) process is the most common method for removing low quantities of ammonium from wastewater, but this is not the usual treatment for high-strength ammonium… Expand

This work proposes a procedure for calibration and validation of complex models by systematically obtaining identifiable parameter subsets according to the available data. Expand
Biological sweetening of energy gases mimics in biotrickling filters.
Removal of hydrogen sulfide from waste and energy-rich gases is required, not only because of environmental health and safety reasons, but also because of operational reasons if such gases have to be… Expand
Polyhydroxyalkanoate synthesis using different carbon sources by two enhanced biological phosphorus removal microbial communities
Abstract Polyhydroxyalkanoate (PHA) is a biodegradable plastic synthesised by bacteria as energy and carbon storage material. PHA production is mostly based on pure cultures operated under sterile… Expand
