Description

The first mechanical street sweeper invented was invented by C.S. Bishop, patented on September 4, 1849. U.S. Patent 6,699. A mechanical street-sweeper is mounted with several rotating disks and/or drums covered in stiff wire bristles. Modern street sweepers are equipped with water tanks and sprayers used to loosen particles and reduce dust. The brooms gather debris into a main collection area from which it is vacuumed and pumped into a collection bin. A regenerative air street sweeper uses forced air to create a swirling knifing effect inside a contained sweeping head and then uses the negative pressure on the suction side to place the road debris inside a containment hopper. The debris laden air is then cleaned and reused to start the process anew. Many regenerative air sweepers are AQMD certified and can pick up particles as small as 10 micrometres or less, a leading cause of stormwater pollution. -see also Wikipedia- Thanks for looking Andreas
