Street sweepers have advanced greatly over the years, but the method of dealing with the dust kicked up by the brooms hasn't changed until recently. The relatively new technology of sweepers with "Waterless Dust Control" is the first departure from water-based dust suppression in many years.
Fresh water is becoming a scarce commodity in many areas of the United States, and some cities have stopped or curtailed sweeping contractors from having free access to water from fire hydrants.
A street sweeper that's operating properly without the recognizable cloud of dust can consume 1,500 gallons of water a day. If water isn't used for dust suppression, the dust that's raised contributes to particulate matter (PM) air pollution. This problem has been identified by the EPA in 59 areas of the U.S. with a combined population of more than 29 million people. Several distinct advantages of waterless sweeping may help make it the wave of the future:
- Greatly reduced water usage
- Reduced air pollution due to improved sweeping efficiency
- Reduction of silt that can contribute to storm water pollution
- The ability to sweep in freezing weather
Waterless. Not watered down.
The Waterless Eagle and Waterless Pelican represent the latest in sweeping technology from the company that's been the leader in sweepers since 1914: Elgin. Both sweepers are capable of handling all types of sweeping conditions and applications without the need to spray water for dust control. The Elgin dust control system operates efficiently at all normal sweeping speeds and conditions.
Patented fan and filter technology minimizes filter loading and extends filter cleaning intervals. Fully flexible main and side broom skirting provide efficient dust capture while allowing aggressive curb cleaning. A full water system is available when wet dust control is desired. The Eagle's dual-engine design, including an engine dedicated to sweeping functions, delivers plenty of power for all applications. Although the waterless system adds slightly to the sweeper cost, Elgin research has shown this would be offset by:
- 20% added productivity because there's no need to make frequent stops to refill with water
- Less time and cost required to clean and maintain the sweeper because it's not caked with mud
- Improved component life because moving parts don't have to work in mud.
Both the Waterless Eagle and Waterless Pelican meet SCAQMD Rule 1186 standards in both wet and dry modes.
