Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems
The approach of wastewater treatment has shifted towards a holistic view in order to achieve sustainability in addition to environmental protection. The aerobic granular sludge (AGS) technology, which relies on the use of fast-settling granular biofilms ca ...
EPFL2013Degradation of 37 emergent contaminants by UV and neutral fenton and photo-fenton in domestic wastewater effluent previously treated by activated sludge
César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Natalia de la Cruz
This study focuses on the removal of 32 selected micropollutants (pharmaceuticals, corrosion inhibitors and biocides/pesticides) found in an effluent coming from a municipal wastewater treatment plant (MWTP) based on activated sludge. Dissolved organic mat ...
Elsevier2012Bacterial Selection during the Formation of Early-Stage Aerobic Granules in Wastewater Treatment Systems Operated Under Wash-Out Dynamics
Christof Holliger, Julien Maillard, Pierre Rossi, David Gregory Weissbrodt, Samuel Lochmatter, Sirous Ebrahimi
Aerobic granular sludge is attractive for high-rate biological wastewater treatment. Biomass wash-out conditions stimulate the formation of aerobic granules. Deteriorated performances in biomass settling and nutrient removal during start-up have however of ...
2012Significance of Rhodocyclaceae for the formation of aerobic granular sludge biofilms and nutrient removal from wastewater
Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter
The competition of two Rhodocyclaceae-affiliated bacterial populations was assessed during the formation and maturation of aerobic granular sludge in two different types of anaerobic-aerobic sequencing batch reactors. Zoogloea spp. (57%) were predominant i ...
Tongji University2011Microbial diversity of aerobic granular sludge: Is it different from activated sludge?
This common presentation was given within the Aerobic Granular Sludge Workshop organized during the IWA Biofilm Conference 2011 (Shanghai, China). The aim was to bring the state-of-the-art knowledge on the microbial diversity present in aerobic granular sl ...
2011MICROBIAL AND BIOMOLECULAR HETEROGENEITY OF AEROBIC GRANULES WITHIN A SINGLE BIOREACTOR ?
David Gregory Weissbrodt, Samuel Lochmatter
Aerobic granulation is considered as a promising alternative to conventional activated sludge in biological wastewater treatment. Instead of forming flocs the bacterial communities aggregate to dense granular biofilms. In the present study, granules were c ...
2010Pharmaceuticals and Personal Care Products (PPCPs) in Effluent Matrices: A Survey of Transformation and Removal during Wastewater Treatment and Implications for Wastewater Management
Pharmaceuticals and personal care products (PPCPs) represent pollutants of emerging concern, originating in surface and drinking waters largely from their persistence in wastewater effluent. Accordingly, a wealth of recent investigations has examined PPCP ...
Royal Society of Chemistry2010Microbial processes in aerobic granules - can we use them to treat wastewater more efficiently?
Christof Holliger, Samuel Lochmatter, Graciela Gonzalez Gil
Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems. Compared to activated sludge, the use of aerobic granular sludge reactors is advantageous because (i) considerably less area is required fo ...
2008Aerobic granular sludge formation and performance at 30 and 35°C in sequencing batch bubble-column reactors
Christof Holliger, Graciela Gonzalez Gil, Sirous Ebrahimi, Sébastien Gabus, Maryam Hosseini
Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems due to their small footprint and their low energy consumption and excess sludge production. The granules developed in such systems have high ...
2008Aerobic granular sludge reactor technology - Aerobic granulation with different substrates
Aerobic granular sludge is a promising alternative to traditional activated sludge basins in wastewater treatment plants (WWTP). Granular sludge has much better settling characteristics than activated sludge. Furthermore it can remove carbon, nitrogen and ...
