This study proposes a modeling strategy for the determination of photocatalytic reaction kinetics in supported reactors. The packed bed studied is designed to degrade formaldehyde and is composed of TiO2-coated Raschig rings. The original…

In water, chlorine reacts with nitrogen-containing compounds to produce disinfection by-products such as nitrogen trichloride which induces ocular and respiratory irritations in swimming pool workers. A technical solution has been used…

This study deals the elimination of formaldehyde present in air of weakly ventilated office by the installation of a purification stand-alone device functioning by photocatalytic oxidation. The process consists first in absorbing gaseous…

Formaldehyde is toxic to humans and is classed as a category 1 carcinogen. Methods have been developed to degrade this compound, but for industrial application, relevant mathematical models are required. This study models a fixed bed photocatalytic…

The elimination of methanal, a carcinogenic compound, has become a priority for industrial or hospital effluent treatment. This study aims to highlight the ability of photocatalysis to degrade methanal and to obtain the corresponding kinetic…

A swimming pool can be considered as a chemical reactor with specific hydraulic and macro-mixing characteristics. The nature of flow into the pool depends on various characteristics, such as water inlets and outlets (number and posi-tion), pool…

L’objectif des travaux présentés dans ce document est la modélisation de l’évolution temporelle de la concentration en NCl3 dans un bassin de natation traditionnel en fonction de ses paramètres de fonctionnement et des conditions de fréquentation…

The anthropogenic substances e.g. urea, ammonia, amino acids and creatinine, found in large quantities in swimming pools, are involved in a very complex series of reactions with chlorine. This leads to the formation of by-products such as trihalomethanes…

In swimming pool water, chlorine reacts with nitrogen-containing compounds to produce disinfection by-products such as trichloramine (NCl3) which induces ocular and respiratory irritations in swimming pool workers. This paper describes…

Outline of reasons and objectives
In France, the number of workers exposed to formaldehyde totals 190,000 spread across over one hundred professions. The need to provide prevention solutions for reducing the exposure of workers exposed to formaldehyde…
