The Many Different Sweepers And Machines Used In Street Sweeping

The very first street sweeping machine was patented in 1849 by its inventor C.S. Bishop. For a long time street sweepers were just rotating disks covered with wire bristles. These rotating disks served as mechanical brooms that swept the dirt on the streets.

In the past these mechanical brooms used in street sweeping were deemed sufficient because they were able to remove the dirt especially the big debris off the streets. But most of the old mechanical machines were not good at sweeping the dirt that has been carried to near the curb. These machines were also not so good at picking up dirt that is very small.

Through the years it has been discovered that cleaning the road of dirt that are 10 microns or smaller are also smaller because this kind of dust and dirt can still carry toxic materials. This is why improvements have been made on the machines. Street sweeping machines are not capable of picking up very small dirt using vacuum. The machines are also now more effective in picking up dirt even near the curb.

In Hamilton, Ontario in the Greater Toronto Area, a study was made on the impact of street sweeping on the quality of the air. It was revealed that a combination of street flushing, street vacuuming and street sweeping lowered the fugitive dusts in the air. Similar studies have been made in other urban areas.

As more studies are conducted, more improvements are also made on the machines. Today, street sweeping is not just part of cleanliness programs in many urban areas including GTA, they are also used as part of storm water quality management programs. This is because it not only helps in improving air quality in urban areas, they are also known to pick up trash, dust and other pollutants that would have otherwise been washed by rain into storm drains. The pollutants and trash that are washed into the storm drains can clog catch basins and can cause floods. When they don't clog the drains, they get washed with the storm water and they end up in natural bodies of water. So it really is important for the public and private sectors in GTA to keep the roads clean.

With more information on significance of street sweeping the machines now work more effectively and efficiently than the machines in the past. Today, the machines used involve the use of regenerative air. Regenerative air street sweeping machines use pressurized air to loosen the dirt on the pavement. Then the machine's vacuum sucks the dirt into a collection bin. Many types of regenerative air machines are certified to pick up really small dirt even those that are smaller than ten microns. The machines used in cleaning roads have really come a long way from the first street sweeper registered in 1849.

Apart from the regenerative air road cleaning machines, road flushing machines are also used to remove dirt from the roads. Pressurized water is used to flush the dirt from pavements and then street vacuums are used to remove all the dirt. A combination of street flushing, street sweeping and street vacuuming is what is known to work the best in removing miniscule dirt and pollutants from the roads.
