Modeling of the deep granular bed filtration of nanoparticles ET2013-004/C2016-100 | 2016

In the case of industrial ultrafine particles filtration by a granular bed, the calculation of the efficiency and the pressure drop evolution is a key step towards the installation design. In this goal, a clogging model based on the expression…
Aerosol scavenging by drops : deriving a collection kernel from microphysical modelling EL2014-015/C2016-007 | 2016

Scavenging aerosol particles by droplets is an efficient way of removing solid particles from gases. Despite its interest for both industrial applications and occupational health, predicting realistic removal rates by means of a simple collection…
Improvement of granular bed filtration performances ET2013-004/C2015-131 | 2015

Some authors highlighted that during the filtration of ultrafine particles, the deposit is essentially located in the first layers of the granular bed. Thus, only a small depth is useful thereby reducing both the operation time between each unclogging…
Modeling granular beds clogging by nanoparticles ET2013-004/C2015-128 | 2015

In the case of industrial ultrafine particles filtration by a granular bed, the calculation of the efficiency and the pressure drop evolution is a key step towards the installation design. In this goal, a clogging model based on the expression…
Optimization of ultrafine particles filtration in granular beds ET2013-004/C2015-044 | 2015

Ultrafine particles are generated by many manufacturing processes: surface processing and coating (thermal spraying ...), machining (drilling, rectification ...), combustion welding, and cutting of metals etc...

Filtration of ultrafine metallic particles produced by thermal spraying processes ET2013-004/C2014-075 | 2014

Industrial filtration installations are confronted with clogging of the filters by ultrafine metallic particles produced by thermal spraying or arc metal-cutting processes. The study, conducted on a pleated filter cartridge and a panel…
Improving the scavenging kernel of aerosol particles by small water drops EL2014-015/C2015-058 | 2015

Scavenging aerosol particles by means of water sprays is an efficient way of removing hazardous dust from the atmosphere. Starting from the work of Wang et al. (1978), we propose to extend its formulation of a theoretical scavenging kernel to particles…
Variations in nitrogen trichloride concentration over time in swimming pool water: Experimental and modeling study NOETUDE/C2015-007 | 2015

The work presented here proposes a model to predict the NCl3 concentration over time in a traditional indoor swimming pool, based on its operating parameters and attendance. The approach used relies on the chemical kinetics of NCl3 formation…
Determination of airborne nanoparticle mass concentration from number concentration using their effective density - Application to ELPI data ET2013-004/C2014-017 | 2014

Nanoparticles are generated by numerous industrial processes like arc welding, thermal metal spraying, combustions. Effective density (e) is among the key characteristics of airborne nanoparticles due to its role in particle deposition in…
Respiratory protection against nanoparticles: elements for a better respirators selection guidance ET2013-006/C2016-122 | 2016

The performance of different types of Respiratory Protective Device (RPD) against
nanoparticles are experimentally determined on a dedicated test bench. The influences of the fit of the facepiece, the breathing rate and the particle size are…
