Bus rids UK of pollution as it runs

London: UK’s largest bus and rail operator, the Go-Ahead Group, has launched a green bus that purifies air as it moves. The Bluestar Bus comes with an attached filter which is manufactured by Pall Aero­space. The filter remo­v­es ultrafine particles from the air and traps them as the bus moves through the streets. As part of a pilot project, the bus plies in Southampton, said an official statement by Go-Ahead.

The operator’s chief executive David Brown said, “We want this pilot to show buses should be looked at as not just the solution to congestion in cities, but also as a solution to the air quality problem.” “As the bus removes the ultrafine particles from the air as it travels along the route, it is helping solve the air quality problems of the city. This bus will clean the air on its route 1.7 times a year to a height of 10 metres, imagine the change we could make to air quality if all buses had this technology,” he stated. Steve Simpson, Pall Aerospace’s Marketing Director outlined that one filter working at an efficiency of 99.5% will make a considerable difference to the environment.

“One filter working at the efficiency of 99.5% will clean the equivalent of 20 million cubic metres of air in one year,” he said. “So that’s the same as saying that on a typical route, working a 10-metre radius, the bus will clean the air within that tunnel 16 times a year,” Simpson claimed, add­ing, “If you factor that over a larger number of buses then you can start to see that it will make a difference.”
