Particle filters on inland ships
The Swiss General Navigation Company of Lake Zürich (ZSG) has now equipped all its 15 motor vessels with particulate filters, capable of removing up to 99 per cent of particulate matter (PM) emissions. Since August 2010, particle filters have been mandatory for all new ships and, wherever feasible and economically viable for the existing fleet. ZSG reports that the material costs for the equipment of its ships amounted to around CHF1.3 million, and that installation takes up to 20 working days per ship.
