2018: Mass transfer and diffusion in the wake of single air bubbles rising in polymer aqueous solutions quantified by PLIF with inhibition

New paper : Mass transfer and diffusion in the wake of single air bubbles rising in polymer aqueous solutions quantified by PLIF with inhibition Based on the planar laser-induced fluorescence with inhibition (PLIF-I) experiments, the mass transfer and diffusion phenomena in the wake of single air bubbles (equivalent diameter ∼ 1–1.4 mm) rising in various aqueous […]

2018 : Escape Classroom: The Leblanc Process—An Educational “Escape Game” – J. Chem. Educ.

An “escape game” activity is proposed to increase stimulation, team group skills, and adaptability in the chemistry classroom. The students follow in the footsteps of Nicolas Leblanc, a young French chemist, who took part in a contest launched by the French Academy of Sciences in 1775 to produce industrial soda ash. By means of scientific […]

2017: Local hydrodynamic investigation by PIV and CFD within a Dynamic filtration unit under laminar flow

Xiaomin Xie, Claude Le Men, Nicolas Dietrich, PhilippeSchmitz, LucFillaudeau https://doi.org/10.1016/j.seppur.2017.04.009 Separation and Purification Technology Abstract To better understand the hydrodynamics in a Dynamic Filtration module (DF), a local investigation within a complex and confined module named Rotating and Vibrating Filtration (RVF) was scrutinized under laminar flow with viscous Newtonian fluid (Remixing = 45). RVF consists of two […]

2017: Local investigations on the gas-liquid mass transfer around Taylor bubbles flowing in a meandering millimetric square channel

Abstract : Gas-liquid mass transfer around Taylor bubbles moving in a meandering millimetric square channel was locally visualized and characterized in the present study. For that, the colorimetric technique proposed by Dietrich et al. (2013) was implemented. With this technique, the evolution of equivalent oxygen concentration fields in the liquid slugs passing through one and […]

2017 : Study of the initial glycerol concentration effects upon bacterial cells adaptation and biodegradation kinetics on a submerged aerated fixed bed reactor using biocell® packing

Abstract: The present work provides an experimental study of the effect of the glycerol concentration on removal performances in a Submerged Aerobic Fixed-Film (SAF) Reactor performing in batch mode. This study consisted in adding various initial substrate concentrations of synthetic solutions (glycerol) in order to assess their effects on biodegradation kinetics and then on bacterial […]

2017 : Absorption of toluene by vegetable oil–water emulsion in scrubbing tower: Experiments and modeling

  Abstract The aim of this work is to study continuous counter-current absorption of Volatile Organic Compounds (VOCs) by an oil–water emulsion. This process enables the treatment of hydrophilic and hydrophobic VOC within a gaseous effluent emitted by chemical or food processing industries. Toluene was chosen as the pollutant in this work because of its […]

2016 : Process-Oriented Review of Bacterial Quorum Quenching for Membrane Biofouling Mitigation in Membrane Bioreactors (MBRs)

  Abstract Quorum Quenching (QQ) has been developed over the last few years to overcome practical issues related to membrane biofouling, which is currently the major difficulty thwarting the extensive development of membrane bioreactors (MBRs). QQ is the disruption of Quorum Sensing (QS), cell-to-cell communication enabling the bacteria to harmonize their behavior. The production of […]
