As part of the call for projects “Innovons pour l’air de nos stations” (Innovating to improve the air in our stations) launched by the lIe-de-France region in 2018, Valérie Pécresse, President of Ile-de-France Mobilités and the Ile-de-France region, Catherine Guillouard, Chief Executive Officer of RATP, and Marie-Ange Debon, Senior Executive Vice President in charge of France, Italy and Eastern and Central Europe at SUEZ Group, officially launched “IP’AIR”, an innovative air treatment solution tested by SUEZ, in partnership with RATP, in the Parisian underground station Alexandre Dumas (Line 2).
Because air quality is the region’s top priority for environment and health, and as part of its “Changeons d’air” (Let’s change our air) policy adopted in 2016, Ile-de-France region has introduced a unique support mechanism for projects that aim to improve air quality in public transport underground areas, called “Innovons pour l’air de nos stations”.
Valérie Pécresse, President of the Ile-de-France region: “Improving air quality in the public transport system is a key factor in our fight against pollution in lle-de-France. I am proud that our “Changeons d’air” policy will offer local residents innovative solutions to reduce pollution in our train and underground stations.”
This policy aims to support projects that offer ways to improve air quality in Ile-de-France’s public transport in the long term. The goal is to provide innovative purifying solutions that capture airborne particles using devices placed on station platforms. A call for projects, managed by the region in partnership with IDFM, RATP, SNCF and AirParif, and with a budget of €1 million, was launched in March 2018. The “IP’AIR” solution offered by SUEZ Group was selected for testing in Alexandre Dumas underground station on line 2.
The “IP’AIR” solution offered by SUEZ will focus on treating fine particles (PM10 and PM2.5) emitted by brake systems in underground stations. The six-month test, which began on 3 June 2019, will assess the solution’s filtration capacity and range.
Catherine Guillouard, Chief Executive Officer of RATP Group: “RATP considers the air quality of its locations as a key importance. With our strong focus on technological improvements, we are delighted to test this innovative device offered by SUEZ and with the support of the Ile-de-France region.”
This test is part of a set of actions taken by RATP to improve air quality in its underground stations:
A pioneering solution for the Paris underground
The “IP’AIR” solution treats air using a positive ionization process. This technology is based on an innovative electrostatic filtration process: a small electric charge is injected into the fine particles which are then attracted, like a magnet, to collection plates. The technical solution is able to treat a large quantity of air (7,500 m3/h) using the same amount of electricity as a bread toaster.
SUEZ will also manage characterisation studies and explore possible recovery channels for the particles collected.
