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.
