- the or each member may have a generally planar form advantageously in the
- shape of a disc although other, for example polygonal shapes, may be used.
- the members are arranged parallel or
- the dimensions of the gaps may be varied as desired, but is preferably less than 10mm and advantageously
- the or each member may be provided with formations in order
- each member may
- the means for moving the or each member may comprise an electric motor driving through a belt drive connected to a shaft to which the
- polluted air may comprise a pipe extending through the or
- each member and defining outlets through which polluted air flows out.
- means for supplying water may also comprise a pipe extending through the or each member also defining outlets through which water may flow.
- the water may be pumped through the pipe by a pump and the
- Impellers may be arranged on the periphery of the or each members so that in operation air is drawn therethrough.
