Particle catch arrangement using static electric field and methods of using same

A particle catch arrangement comprising a first object with a surface that can be charged, a second object with a surface that can be charged, a generator arranged to generate a positive charge to the first object's surface that can be charged and optionally a negative charge to the second object's surface that can be charged and to generate a static electric field between the surfaces, wherein at least part of the particle catch arrangement is part of or integrated with an object comprising street furniture selected from the group consisting of a sound barrier, a crash barrier, a tunnel wall, a road sign, a traffic information system, a street lamp and a traffic light, and wherein the generator is arranged to apply a voltage of 1.5-50 kV to the surface of the first object.

A method for collecting smut, fine dust and exhaust gas particles in polluted air over a geographical object selected from the group consisting of a road, an open place and a built-on area, the method comprising:

• (i) providing (a) a first object with a surface that can be charged, (b) a second object with a surface that can be charged, (c) a generator arranged to generate a positive charge to the first object's surface that can be charged and optionally a negative charge to the second object's surface that can be charged, and
• (ii) generating a voltage of 1.5-50 kV to the first object's surface,
• wherein at least part of a particle catch arrangement is part of or integrated with an object comprising street furniture selected from the group consisting of a sound barrier, a crash barrier, a tunnel wall, a road sign, a traffic information system, a street lamp and a traffic light.
