Evolution of Microbial Communities and Nutrient Removal Performances of Aerobic Granular Sludge during Change of Substrates
Christof Holliger, Julien Maillard, Aline Sondra Adler, Arnaud Michel Gelb, Valérie Berclaz, Marie Christelle Horisberger
Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system, allowing substantial space, energy and chemichal products savings. Basic understanding of this processes has mainly been obtained in ...
2018Evolution of microbial communities in aerobic granular sludge during changes in wastewater composition
Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger
Aerobic granular sludge (AGS) is an emerging technology offering an alternative wastewater treatment with a reduced footprint compared to conventional activated sludge systems. Basic understanding of AGS has mainly been obtained in lab-scale reactors fed w ...
2018Scale-up of phosphate remobilization from sewage sludge in a microbial fuel cell
Christos Comninellis, Fabian Fischer, Alain-François Grogg, Marc Sugnaux, Thomas Egli, Géraldine Zufferey
Phosphate remobilization from digested sewage sludge containing iron phosphate was scaled-up in a microbial fuel cell (MFC). A 3 litre triple chambered MFC was constructed. This reactor was operated as a microbial fuel cell and later as a microbial electro ...
Elsevier Sci Ltd2016Identification of microorganisms in Aerobic Granular Sludgeactively involved in biological phosphorus removal
One of the aims of the treatment of domestic and industrial wastewater is the removal of phosphorus prior to discharge into the environment. Since phosphorus concentrations in wastewater exceed the requirement of bacterial growth, biological phosphorus rem ...

2016Evolution of microbial communities and nutrient removal performances in aerobic granular sludge sequencing batch reactor during change of substrate
Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger
Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system. As AGS has enhanced settling abilities and provides different redox conditions across the granules at the same time, the processes ba ...

2016Micropollutant degradation, bacterial inactivation and regrowth risk in wastewater effluents: Influence of the secondary (pre)treatment on the efficiency of Advanced Oxidation Processes
César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Anoys Magnet
In this work, disinfection by 5 Advanced Oxidation Processes was preceded by 3 different secondary treatment systems present in the wastewater treatment plant of Vidy, Lausanne (Switzerland). 5 AOPs after two biological treatment methods (conventional acti ...
Elsevier2016Ammonia as an in-situ sanitizer: inactivation kinetics and mechanisms of the ssRNA virus MS2 by NH3
Tamar Kohn, Loïc Decrey, Shinobu Kazama, Kai Udert
Sanitizing human and animal waste (e.g., urine, fecal sludge or grey water) is a critical step in reducing the spread of disease and ensuring microbially safe reuse of waste materials. Viruses are particularly persistent pathogens and can be transmitted th ...
2015Faecal sludge treatment: Optimization of Ascaris eggs enumeration and inactivation, and start-up of an anaerobic thermophilic acid-phase digester
Faecal sludge (FS) accumulates in onsite sanitation technologies, which play a prevailing role in low- and middle-income countries. However, FS management is generally lacking. FS is usually directly discharged in the environment despite its high organic l ...
