Assessment of bacterial and structural dynamics in aerobic granular sludge biofilms

Christof Holliger, Yoan Rappaz, David Gregory Weissbrodt

Aerobic granular sludge (AGS) is based on self-granulated flocs forming mobile biofilms with a gel-like consistence. Bacterial and structural dynamics from flocs to granules were followed in anaerobic-aerobic sequencing batch reactors (SBR) fed with synthe ...

Optimization of Reactor Startup and Nitrogen Removal of Aerobic Granular Sludge Systems

Samuel Lochmatter

Aerobic granular sludge (AGS) in sequencing batch reactors (SBR) has recently made its proofs as full-scale technology for the biological treatment of urban wastewater. In contrast to conventional flocculent activated sludge, microorganisms aggregate to de ...

Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems

David Gregory Weissbrodt

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 ...

Kinetics of the Decomposition of Hydrogen Sulfide in a Dielectric Barrier Discharge Reactor

Albert Renken, Lioubov Kiwi

Kinetics of hydrogen sulfide (H2S) decomposition to hydrogen and sulfur was investigated in a nonthermal plasma dielectric barrier discharge (NTP-DBD) reactor operated under ambient conditions. The reactions were carried out with a fixed flow rate and vary ...

TRACE and TRAC-BF1 Benchmark Against Leibstadt Data During the Event Inadvertent Opening of Relief Valves

Damar Canggih Wicaksono

In framework of introducing TRACE code to transient analyses system codes for Leibstadt Power Plant (KKL), a conversion process of existing TRAC-BF1 model to TRACE has been started within KKL. In the first step, TRACE thermal-hydraulic model for KKL has be ...

Heat Management in Single and Multi-injection Microstructured Reactors: Scaling Effects, Stability Analysis, and Role of Mixing

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid, Julien Haber

The exothermic reactions with fast intrinsic kinetics when carried out in conventional reactors are often limited by heat transfer. This results in the formation of hot spots, which affects product distribution of complex reactions and may lead to reactor ...

Appraisal of Core Analysis Methods against Zero-Power Experiments on Full-Scale BWR Fuel Assemblies

Flavio Dante Giust

The present doctoral research aims at the appraisal of nodal core simulators used for the calculation of commercial boiling water reactor (BWR) cores, against measurements carried out at the Paul Scherrer Institute under the LWR-PROTEUS experimental progra ...

Dynamics of Microbial Community Structure of and Enhanced Biological Phosphorus Removal by Aerobic Granules Cultivated on Propionate or Acetate

Christof Holliger, Graciela Gonzalez Gil

Aerobic granules are dense microbial aggregates with the potential to replace floccular sludge for the treatment of wastewaters. In bubble-column sequencing batch reactors, distinct microbial populations dominated propionate-and acetate-cultivated aerobic ...

Kinetic assessment and modeling of an ozonation step for full-scale municipal wastewater treatment: Micropollutant oxidation, by-product formation and disinfection

Urs von Gunten, Juliane Hollender, Hansruedi Siegrist

The kinetics of oxidation and disinfection processes during ozonation in a full-scale reactor treating secondary wastewater effluent were investigated for seven ozone doses ranging from 0.21 to 1.24 g O-3 g(-1) dissolved organic carbon (DOG). Substances re ...

A novel compact reactor for three-phase hydrogenations

Albert Renken, Lioubov Kiwi, Madhvanand Namadeo Kashid, Martin Grasemann

A novel reactor based on a bubble column staged by structured catalytic layers with integrated cross flow micro-heat-exchangers (HEX) was designed and tested in the solvent free hydrogenation of 2-methyl-3-butyn-2-ol (MBY) aiming on process intensification ...
