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 ...

Significance 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 ...

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 ...

Extraordinarily efficient conduction in a redox-active ionic liquid

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer, Guido Rothenberger, Verner Thorsmolle

Iodine added to iodide-based ionic liquids leads to extraordi- narily efficient charge transport, vastly exceeding that expect- ed for such viscous systems. Using terahertz time-domain spectroscopy, in conjunction with dc conductivity, diffusivity and visc ...
