Modeling the PAO-GAO competition: Effects of carbon source, pH and temperature
Carlos M. Lopez-Vazquez,Adrian Oehmen,Christine M. Hooijmans,Damir Brdjanovic,Huub J. Gijzen,Zhiguo Yuan,Mark C.M. van Loosdrecht +6 more
TL;DR: Which conditions were favorable for the existence of PAO and, therefore, beneficial for the biological phosphorus removal process in sewage treatment plants were assessed.
Journal ArticleDOI
Long term effects of salt on activity, population structure and floc characteristics in enriched bacterial cultures of nitrifiers.
M.S. Moussa,D.U. Sumanasekera,S.H. Ibrahim,H.J. Lubberding,Christine M. Hooijmans,Huub J. Gijzen,M.C.M. van Loosdrecht +6 more
TL;DR: Increased salt concentrations resulted in better settling characteristics of the nitrifying sludge and despite the change in population composition similar kinetics as before the salt stress were observed.
Journal ArticleDOI
Fate and biological effects of silver, titanium dioxide, and C60 (fullerene) nanomaterials during simulated wastewater treatment processes.
TL;DR: Significant fractions of fn-Ag were associated with colloidal material which suggests that efficient particle separation processes (sedimentation or filtration) could further improve removal of NM from effluent.

Effect of different operational conditions on biofilm development, nitrification, and nitrifying microbial population in moving-bed biofilm reactors
João Paulo Bassin,Robbert Kleerebezem,Alexandre S. Rosado,M.C.M. van Loosdrecht,Márcia Dezotti +4 more
TL;DR: Polysaccharide and protein concentrations proved to be good indicators of biomass development and detachment in MBBR systems and free nitrous acid and free ammonia were likely the inhibitors for ammonium- and nitrite-oxidizing bacteria.
Journal ArticleDOI
Extension of ASM3 for two-step nitrification and denitrification and its calibration and validation with batch tests and pilot scale data.
TL;DR: The Activated Sludge Model No.3 (ASM3) was extended for two-step nitrification and two- step denitrification in order to better describe nitrite dynamics especially during the treatment of communal wastewater.

Standard methods for the examination of water and wastewater
TL;DR: The most widely read reference in the water industry, Water Industry Reference as discussed by the authors, is a comprehensive reference tool for water analysis methods that covers all aspects of USEPA-approved water analysis.
Activated sludge models ASM1, ASM2, ASM2d and ASM3 (in Japaneese)
TL;DR: A complete overview of the Activated Sludge Model (ASM) family can be found in this article, where the authors present ASM1, ASM2 and ASM3 together for the first time.

Stoichiometric Model of the Aerobic Metabolism of the Biological Phosphorus Removal Process
TL;DR: The uptake of phosphate and storage as polyphosphate is shown to have a direct effect on the observed oxygen consumption in the aerobic phase of the biological phosphorus removal process.
