Bacterial versus fungal laccase: potential for micropollutant degradation
David Andrew Barry, Christof Holliger, Julien Maillard, Jonas Margot
Relatively high concentrations of micropollutants in municipal wastewater treatment plant (WWTP) effluents underscore the necessity to develop additional treatment steps prior to discharge of treated wastewater. Microorganisms that produce unspecific oxida ...
2013Two-phase frictional pressure drops in U-bends and contiguous straight tubes for different refrigerants, orientations, tube, and bend diameters: Part 2. New models (RP-1444)
John Richard Thome, Ricardo Lima
In the first part of this article (Silva Lima and Thome 2012b), new experimental frictional pressure drop data in U-bends were presented and discussed. The experimental data were obtained for R410A and R134a at two saturation temperatures (5 degrees C and ...
Taylor & Francis Inc2012A sustainable production of algal biomass integrating wastewater treatment and bioenergy generation
Christian Ludwig, Céline Terrettaz, Mariluz Bagnoud
This project aims to demonstrate the feasibility of producing renewable microalgae biomass using as a main nutrient source a secondary wastewater stream. It is planned to purify the wastewater by the growth of algal biomass while producing a feedstock that ...
2012Two-phase frictional pressure drops in U-bends and contiguous straight tubes for different refrigerants, orientations, tube, and bend diameters: Part 1. Experimental results (RP-1444)
John Richard Thome, Ricardo Lima
Over the years, much research has been conducted on two-phase flows in straight tubes because these tend, in length, to be predominant in two-phase systems. However, two-phase heat exchangers can also have singularity elements, where the most common type i ...
Taylor & Francis Inc2012Two-phase flow patterns in U-bends and their contiguous straight tubes for different orientations, tube and bend diameters
John Richard Thome, Ricardo Lima
In two-phase systems there are many singularities in piping systems, one of which in particular are U-bends (also called 180 degrees return bends or U-tubes) found very often in air conditioning coils, refrigerant systems, etc. Contrary to the literature c ...
Elsevier2012Microbial 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 ...
2011Effects of sonochemical parameters and inorganic ions during the sonochemical degradation of crystal violet in water
César Pulgarin, Fernando Guzman Duque
This work deals with the ultrasonic degradation (800 kHz) of crystal violet (CV) under different experimental conditions. The effects of saturating gas (argon, carbon dioxide and air), CV concentration (2.45-1225 mu mol L-1), pH (3-9) and power (20-80 W) w ...
2011Mitigating Cr Contamination by Hot Air Filtering in Solid Oxide Fuel Cells
Jan Van Herle, Christian Ludwig, Aïcha Hessler-Wyser, Josef Andreas Schuler
Cr contamination, generated by system components located upstream a solid oxide fuel cell (SOFC) and responsible for Cr-poisoning induced air electrode performance degradation, must be suppressed by hindering the access of Cr pollutants to the cathode comp ...
Electrochemical Society2011Self-entrainment of air on stepped spillways
The pseudo-bottom-inception point related to air entrainment is located further upstream on stepped spillways than on smooth spillways, for otherwise identical conditions. Its position is relevant concerning cavitation aspects, flow losses and flow depths. ...
