Role of ammonia-oxidizing bacteria in micropollutant removal from wastewater with aerobic granular sludge

David Andrew Barry, Christof Holliger, Jonas Margot, Samuel Lochmatter

Nitrifying wastewater treatment plants (WWTPs) are more efficient than non-nitrifying WWTPs to remove several micropollutants such as pharmaceuticals and pesticides. This may be related to the activity of nitrifying organisms, such as ammonia-oxidizing bac ...

Identification of microorganisms in Aerobic Granular Sludgeactively involved in biological phosphorus removal

Arnaud Michel Gelb

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 ...

Scale-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 ...
