Stability of a liquid layer draining around a horizontal cylinder: Interplay of capillary and gravity forces

François Gallaire, Shahab Eghbali, Simeon Vladimirov Djambov

We study the drainage of a viscous liquid film coating the outside of a solid horizontal cylinder, where gravity acts vertically. We focus on the limit of large Ohnesorge numbers Oh, where inertia is negligible compared to viscous effects. We first study t ...

Force microscopy of the Caenorhabditis elegans embryonic eggshell

Martinus Gijs, Thomas Lehnert, Roger Philippe Krenger

Assays focusing on emerging biological phenomena in an animal's life can be performed during embryogenesis. While the embryo of Caenorhabditis elegans has been extensively studied, its biomechanical properties are largely unknown. Here, we demonstrate that ...

Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes

Wendy Lee Queen, Daniel Teav Sun

Radioactive iodine-129 (I-129) and technetium-99 (Tc-9(9)) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et aL (2019), natural and engineer ...

Velocities, Residence Times, Tracer Breakthroughs in a Vegetated Lysimeter: A Multitracer Experiment

Andrea Rinaldo, Michaël Bensimon, Paolo Benettin, Pierre Claude Jean Queloz

Flow velocities, residence times, and tracer breakthroughs at the lysimeter scale are affected by matrix properties and preferential flow. Despite their relevance to transport processes, however, the relative timing of preferential flow, and its link to tr ...

Evolution of Microbial Communities and Nutrient Removal Performances of Aerobic Granular Sludge during Change of Substrates

Christof Holliger, Julien Maillard, Aline Sondra Adler, Arnaud Michel Gelb, Valérie Berclaz, Marie Christelle Horisberger

Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system, allowing substantial space, energy and chemichal products savings. Basic understanding of this processes has mainly been obtained in ...

Modeling Hydraulic Transport and Anaerobic Uptake by PAOs and GAOs During Wastewater Feeding in EBPR Granular Sludge Reactors

Christof Holliger, David Gregory Weissbrodt

New-generation bioprocesses using granular sludge aim for a high-rate removal of nutrients from wastewater with low footprint. Achieving enhanced biological phosphorus removal (EBPR) relies on the design of sludge beds and wastewater feeding conditions to ...

Super-fine powdered activated carbon (SPAC) for efficient removal of micropollutants from wastewater treatment plant effluent

Tamar Kohn, Florence Bonvin, Livia Jost, Léa Cécile Randin

In an effort to mitigate the discharge of micropollutants to surface waters, adsorption of micropollutants onto powdered activated carbon (PAC) after conventional wastewater treatment has been identified as a promising technology for enhanced removal of ph ...

Organic Contaminant Abatement in Reclaimed Water by UV/H2O2 and a Combined Process Consisting of O-3/H2O2 Followed by UV/H2O2: Prediction of Abatement Efficiency, Energy Consumption, and Byproduct Formation

Urs von Gunten, Minju Lee, Yun Ho Lee, Silvio Canonica

UV/H2O2 processes can be applied to improve the quality of effluents from municipal wastewater treatment plants by attenuating trace organic contaminants (micropollutants). This study presents a kinetic model based on UV photolysis parameters, including UV ...
