Dust Control – Soil Stabilization – Erosion Control

Posts Tagged ‘dust particles’

Most Americans are not fully aware of the road dust problem that exists across the nation. This dust is of a different makeup from what is found around in most homes. The dust that accumulates around on the furniture is made up of some dirt particles, but its main component is dead human skin cells that have fallen off the occupants of the dwelling.

For a particle to be considered dust, it must be smaller than 500 micrometers in size. This is why HEPA filters are used on vacuum cleaners and as part of the HVAC units in the homes, they trap 99.97% of all particles that are 0.03 micrometers in size.

Nuisance dust from the roads has a completely different composition and source. This dust is produced when the soil is disrupted and made airborne from wind or a passing vehicle, pollutants in the air, and the occasional volcanic dust that lingers around in the atmosphere.

Floor Sweepers and Floor Scrubbers from Tennant Features Tennant sweepers provide excellent debris pick up and dust control. They deliver superior, long lasting results even in the harshest environments with continuous up time and powerful sweeping performance.

Tennant sweepers control dust particles down to 3 microns. Tennant’s latest innovation, SweepSmart™, filters dust particles down to 0.5 microns.

1. Side brush sweeps debris into the path of the main broom
2. Skirt system creates a seal to maximise dust collection
3. Main broom contacts floor surface and flicks dust and debris into the hopper
4. Perma-Filter™ shifts airflow and forces the majority of dust, debris and moisture into hopper
5. Cyclonic filter system channels airflow to further remove dust and moisture from the air, redirecting it into the hopper
6. Nanofibre canister filter traps sub-micron dust particles resulting in clean air exhaust
7. The ErgoSpace™ operator compartment increases operator comfort, visibility and safety

Applications for Tennant Sweepers.

The Tennant SweepSmart™ system, available on the new S30 ride-on sweeper, uses a 3-stage dust control system for unrivalled performance.

* The first stage Perma-Filter™ keeps large bulky debris in the hopper
* The second stage cyclonic filter redirects fine dust and moisture back into the hopper
* The third stage flame-retardant nanofibre canister filter, filters sub-micron dust particles down to 0.5 microns

Benefits of the Sweepers

* Easy to use and it is built to last
* Extremely flexible, designed to clean a variety of surfaces indoors and out, without compromising performance
* Offers unparalleled safety with reduced noise levels, better sightlines and easy operation as well as significantly improved air quality

Tennant Industrial Sweepers include:

* 110 Walk-Behind Sweepers
* S8 Walk-Behind Sweepers
* S10 Walk-Behind Sweepers
* 3640 Walk-Behind Sweepers
* S12 Small Ride On Sweepers
* 6100 Small Ride On Sweepers
* 6200 Small Ride On Sweepers

The dust from a mine is significantly different from the dust you find in your home. Dust in your home primarily consists of dead skin while mine dust is almost exclusively a mineral in a fine powder form.

Most written definitions of mine dust include the following: dust from drilling, blasting, smashing or handling of rock. The majority of the dust created by one of these activities are too large to stay in the air for an extended period of time and account for about 40 percent of all dust created at a mine site. The remainder is less than 10 micrometers in size. The majority of these particles is less than 2.5 micrometers and come from the exhaust of equipment used on the mining site.

The smallest size particle is what is most hazardous to the population’s health. The larger dust particles are an eye sore and are cost a lot to clean up, but are less hazardous to one’s health.

The smaller particles do make certain health hazards that include respiratory problems due to the fact that they are in the air that is breathed in to the lungs. This can be minimized if mining personnel were to wear masks designed to filter out the dust.

The Occupational Safety and Health Administration (OSHA) is a useful resource on controlling dust. In Chapter 3 of the OSHA handbook, it explains why dust should be controlled, the various forms of dust control systems that are available, and how to select the correct one, and how to design a water spray system to limit the spread of dust.

Some reasons why dust should be controlled are to reduce and prevent the chance of dust explosions and fires. Also the reduction of accidents is greater with better visibility of the workplace. Reducing dust will also decrease the wear and tear on equipment and minimize the need for maintenance. For employees, less dust will require less protective gear that is needed as well as reduce the possibility of foul odors, which can have a negative effect on productivity.

Here is the problem. When you use a dust suppression product like Top-Seal Dust Control, You cause the soil to become less permeable. Thus Causing the water in the lake to stay in the lake. Eventually you will Flood your Solar Farm and then it will just be a nice place to dive.

In Los Angeles, California, the city’s Department of Water and Power (DWP) is eyeing flat, dusty, arid Owens Lake as the potential site for a future mega-solar farm, but the initiative is focused less on clean, renewable solar energy than on preventing the interminable dust storms generated by the dry lake bed.

Owens Lake started to run dry when, in 1913, the city began diverting water from the Owens River. By 1926, the former lake was a shallow hardpan. Today, it ranks as the largest single source of PM10 dust (windborn dust particles smaller than 10 microns) in the United States. In fact, one estimate suggests the lake produces up to 8 million metric tons per year.

The DWP thinks that covering 616 acres of the lake bed with solar panels could cut down on dust storms, which threaten the health of nearby Keeler and Ridgecrest residents by delivering up to 23 times the amount of airborne particulate matter federal levels suggest as safe.

Techniques for removing dust from the air have varied over the years. During that time, methods have focused on a dust collection and suppression system. The difference between a dust collector and a dust suppression system is how the dust is initially treated. Dust collectors form a vacuum to capture the dust and remove it from the surrounding air. It is then transferred to a filter or bag for proper disposal. A dust suppression system does not attempt to remove the dust from the physical area. Instead it places it back to its source. Best of all, a dust suppression system is more affordable.
