are killed each year by pollutants attached to small-micron dust particles, and 1,000,000 more sustain serious lung impairment. According to EPA estimates, 30,000 people in the U.S. Either way, these particles pose an environmental challenge. Thats because with rainfall they tend to run off into stormwater systems as total suspended solids (TSS), or to get pounded into the air by passing cars (or blown into the air by wind) as fugitive dust (PM-10s). These small-micron particles are now seen to pose a significant environmental concern. A high level of increased emphasis, by the EPA and others, is now being placed upon the removal of small-micron debris as a Best Management Practice (BMP) for reducing stormwater runoff pollution. From an environmental standpoint, it is exactly this material that it is most important to remove. It has been confirmed that even though a street may look clean (before or after being swept), there still may be a significant loading of small-micron, pollution-laden debris on it. Thats because recent studies have shown that more than 50% of heavy metals and other serious pollutants are attached to particles that are 60 microns in size and smaller (as a comparison, a human hair is about 70 microns in width), even though particles of this size compose a relatively insignificant amount of the total weight and volume of a typical sweepers hopper load. Environmental Protection Agency (EPA), as well as by public works professionals and others throughout the country. Today, however, this reason for sweeping is undergoing significant re-appraisal by the U.S. It has been so-called because of consensus that if a street looked clean, it was clean. Since its inception, sweeping has been used to remove what might be termed cosmetic or political debris from roadways and other paved surfaces. The information in this article was last updated in December of 2010 First, a brief overview is provided of some of the emerging concerns in the sweeping industry. and international sweeping industry professionals in reaching a better understanding of the differences between the major types of sweeping equipment being used in the American road sweeping marketplace. Many customers tell us they use an electric broom for quick pickups and daily sweeping duties, then use a vacuum for a weekly deep clean.An Overview of Sweeping Equipment TechnologyĪn Overview of Power Sweeping Equipment Technology This sweeping industry informational white paper is a collaboration between Ranger Kidwell-Ross, Editor of, and Roger Sutherland, Vice-President of Pacific Water Resources, Inc. NOTE: Electric brooms are not well suited for carpet cleaning – we recommend using a vacuum to clean carpets and deep-pile rugs.
