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 ...

Ideal MHD spectrum calculations for the ARIES-CS configuration

Wilfred Anthony Cooper

Ideal MHD stability calculations for the ARIES compact stellarator (ARIES-CS) reactor design (Najmabadi et al 2008 Fusion Sci. Technol. 54 655) show a spectrum of instabilities. The ARIES design considered is a three field-period stellarator with engineeri ...

Scalar and pseudoscalar Higgs production in association with a top-antitop pair

Valentin Hirschi

We present the calculation of scalar and pseudoscalar Higgs production in association with a top-antitop pair to the next-to-leading order (NLO) accuracy in QCD, interfaced with parton showers according to the MC@NLO formalism. We apply our results to the ...

Improvement of the Decay Heat Removal Characteristics of the Generation IV Gas-cooled Fast Reactor

Aaron Simon Epiney

Gas cooling in nuclear power plants (NPPs) has a long history, the corresponding reactor types developed in France, the UK and the US having been thermal neutron-spectrum systems using graphite as the moderator. The majority of NPPs worldwide, however, are ...

Heavy-gas injection in the Generation IV gas-cooled fast reactor for improved decay heat removal under depressurized conditions

Rakesh Chawla, Konstantin Mikityuk, Aaron Simon Epiney

Decay heat removal is a key safety and design issue for the Generation IV gas (helium)-cooled fast reactor. This paper investigates the natural convection capability of the dedicated DHR loops under depressurized conditions while injecting a heavy gas into ...

Structured catalytic wall microreactor for efficient performance of exothermic reactions

Lioubov Kiwi, Bryan Bromley, Marina Ruta, Turan Eslanloo Pereira

A novel microreactor with structured catalytic wall (SCWMR) has been developed for highly exothermic, gas/solid reactions and tested for the selective acetylene hydrogenation. The reactor design is similar to the so-called "slit microreactor". The structur ...

The carbon source governs the population dynamics of phosphate accumulating organisms in aerobic granules

Christof Holliger, Olivia Zanoletti, Samuel Lochmatter, Graciela Gonzalez Gil

Aerobic granules are quasi-spherical biofilms mainly composed of self-immobilized mixed microbial communities. The application of aerobic granules to treat domestic and low-strength industrial wastewaters is gaining attention because granules can accommoda ...
