Study of the coupling of different indoor air pollution treatment techniques for the removal of nitrogen oxides, VOCs and particulate matter

P05I3   Indoor air pollution is one of the biggest concerns in terms of public health. In France, it was estimated that indoor air pollution would bring about a socio-economic cost of around 20 billion euros per year. In this context, the treatment of this kind of pollution has become an important challenge.

   The CUBAIR project aimed to develop and evaluate an original prototype, combining air purification techniques such as adsorption, filtration and photocatalysis. The evaluation of the performance of this prototype was carried out in situ during 10 months and different measurements were taken for parameters and pollutants such as nitrogen oxides and VOCs with emphasis on BTEX and some aldehydes. Other measurement campaigns were carried out to determine particle concentrations (PM1, PM2.5, PM10), microbiological parameters, comfort parameters (temperature, relative humidity), as well as the air flow of the prototype. The results show a good removal efficiency (RE) of nitrogen oxides with a RE of 86% for the NO2. Likewise, PM1 was reduced by more than 75%.

Abstract

  Indoor air pollution is one of the biggest concerns in terms of public health. In France, it was estimated that indoor air pollution would bring about a socio-economic cost of around 20 billion euros per year. In this context, the treatment of this kind of pollution has become an important challenge.

   The CUBAIR project aimed to develop and evaluate an original prototype, combining air purification techniques such as adsorption, filtration and photocatalysis. The evaluation of the performance of this prototype was carried out in situ during 10 months and different measurements were taken for parameters and pollutants such as nitrogen oxides and VOCs with emphasis on BTEX and some aldehydes. Other measurement campaigns were carried out to determine particle concentrations (PM1, PM2.5, PM10), microbiological parameters, comfort parameters (temperature, relative humidity), as well as the air flow of the prototype. The results show a good removal efficiency (RE) of nitrogen oxides with a RE of 86% for the NO2. Likewise, PM1 was reduced by more than 75%.

What are cookies?

   A cookie is a text file stored in a user’s web browser on any device they use to access a website that holds information regarding the user’s visit, such as preferences. When the user returns, the browser provides the cookie with the stored information to the site.

What cookies are used for?

   Cookies are used for adjusting a website’s content to fit a user’s preferences and optimize the website. They store useful information that improve the user’s experience of a website. They are most commonly used for:

  •     Recognizing the type of device a user is browsing with and any preferences applied to optimize the website specifically for the device.
  •     Creating statistics that help website owners to understand how their users interact with their website, which allows them to improve their structure and content.

What types of cookies are used?

   There are two types of cookies: persistent cookies and session cookies. Persistent cookies remain on your hard drive for a period of time specified in the cookie’s file parameters or until removed manually. When you return to a website and it requires you to login again despite previously storing your login information, it is usually because the persistent cookie expired; this helps to increase security while maintaining accessibility.

   Session cookies, on the other hand, are used temporarily and expire once the website or browser is closed. They are used to track user activity on a website during a single visit. When a website requires that you verify your age or location once every visit before allowing you to view content and without requiring additional personal details, that is a session cookie at work.

Do cookies include personal data?

   If there is a need for the collection of personal information, such as for creating accounts, then cookies may store personal information. However, it is required by data protection law that users are informed of the collection of personal data. This data will also be encrypted to render it inaccessible for unauthorized users.
