“We chose the Aussie pumps high pressure pumps because of their big flow, high pressure performance and overall reliability” said Water Trucks Direct Managing Director, Brenden Bastian. “The 5 year warranty offered by Australian Pump is a tremendous bonus” he said.

Water Trucks use both high volume transfer pumps for fast filling in 3”, 4” and 5” sizes. The big volume pumps are either PTO or hydraulic drive with diesel options being available. Smaller tankers in the 10,000 litre range use Aussie 3” self priming gushers that produce flows of up to 1,500 litres per minute. Genuine Japanese Honda petrol engines, one of the major features offered by Australian Pump and Yanmar diesel drives are both used depending on the application and customer’s requirements.

Each module has a capacity of 2,000 litres and provides an integrated baffle arrangement that eliminates surgies on corners or from quick stops or starts. “The modular tanker design means we can produce tankers that use much the same componentry from 4200 litres to 30,200 litres depending on the customer’s requirement and the chassis available” said Brenden Bastian.

The tankers come with a unique rear spray bar and water distribution system that enables real flexibility in tanker operations. For example, tankers can load water fast from either a stand pipe or draw water from streams, rivers or dams.

Water delivery can be either through the spray bar or via a hose reel with up to 30 metres of hose and a high pressure fire fighting style nozzle that enables the operator to carry out watering functions or wash down on construction sites. Tankers can be kitted out with water cannons and both front and rear sprayer heads whilst an Aussie high pressure hydraulic driven pressure washer in capacities of up to 4,000 psi is also available as a handy accessory.

“The high pressure water blaster can utilize the water from the tank to clean plant and equipment in the field, facilitating service and maintenance procedures on earthmoving and mining equipment” said Mr. Bastian.

The high pressure pump is an Aussie Fire Chief, and offers the following features:

* The high pressure pumps are offered in either diesel or petrol drive configurations
* These big capacity high pressure pumps provide flows of up to 500 litres per minute and heads as high as 100 metres
* The pumps offer over 150 psi
* Australian Pump engine drive tanker pumps are available in both manual and electric start
* The electric start on the high pressure pumps enables the operator to have the facility of operating the pump function from the cab

BNSF, as well as the Union Pacific Railroad, have spent hundreds of millions of dollars already to reduce coal dust since a 2005 derailment was blamed on coal dust accumulation on the tracks.

But industry officials say additional coal dust suppression measures may be required, costing millions more.

Possible solutions include covering cars, applying a latex coating, or filling cars with less coal.

American Public Power Association estimates whatever method is chosen will add $100 million annually to the cost of shipping coal out of the Powder River Basin.

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.

Another way dust can be decreased on the mining site is with the use of a dust suppression system. This is where water is sprayed over piles of rocks and the ground, particularly in the loading areas. These particles will be absorbed by the water thus become too heavy to stay in the air and eventually drop back onto the ground from which they came

The large trucks that are used in the mining area are also responsible for kicking up a great deal of dust, but most of that is fugitive dust from the ground soil and not the mine dust.

Additional information can be found regarding how an erosion control blanket can be used to keep dust contained, especially in construction areas where dust is most prevalent. Check out the Dust Stop Zone for more Free information.

Received for publication January 31, 2009. Magnesium chloride (MgCl2)-based dust suppression products are commonly used throughout western United States on nonpaved roads for dust suppression  and road stabilization by federal, state, and county transportation agencies.

The environmental implications of annually applying these products throughout spring and summer months on adjacent stream chemistry are not known. Sixteen streams were monitored biweekly for 1 to 2 yr in two Colorado counties for a suite of water quality variables up and downstream of nonpaved roads treated with MgCl2–based dust suppression products.

Eight of 16 streams had significantly higher downstream than upstream concentrations of chloride or magnesium over the entire monitoring period (p  0.05). Mean downstream chloride concentrations ranged from 0.17 to 36.2 mg/L and magnesium concentrations ranged from 1.06 to 12.8 mg/L. Several other ions and compounds, including those commonly found in dust suppression products such as sodium, calcium, and sulfate, were also significantly higher downstream at some sites.

Downstream electrical conductivity (EC), chloride and magnesium concentrations were positively correlated with road surface area draining water toward the stream and yearly amount of MgCl2 applied (R2 = 0.75, 0.51 and 0.49, respectively), indicating that road managers can limit the amount of product entering roadside streams by assessing drainage characteristics and application rates in best management practices. Although MgCl2–based dust suppressants did move into some roadside streams, the concentrations detected were below those reported to adversely affect fresh water aquatic organisms, but the ultimate fate of these ions in Colorado waterbodies are not known.

Soils Control International has accomplished the same results with their product, Top-Seal Dust Control 

DuPont Australia’s groundbreaking work to reduce dust emissions from trains carrying coal and to improve air quality recently earned two industry awards:

* The Australian Mining Prospect Award for Excellence in Environmental Management
* The Australian Bulk Handling Award for Dust Control Technology

“Dust emissions from trains transporting coal are a serious problem for the mining industry and a constant source of complaint from communities near rail lines,” said Leong Mar, Technology Centre manager. “Australia’s hot, dry climate significantly increases the potential for dust during the trip from the mine to the port.”

DuPont and Anglo Coal worked on a joint project at Callide Mines that cut coal dust emissions from 50% to 90%, depending on coal characteristics and conditions. A spray system treats the surface of loaded coal with DuPont™ Dusgon® dust suppression agent. The design is seamlessly integrated with normal operations and provides tangible benefits to the workers, local community and the environment.

DuPont Australia Managing Director Hutch Ranck said the awards reflect the company’s commitment to developing products that protect people and the environment.

“Congratulations are in order to the dust suppression team for their determination and perseverance in successfully commercializing this technology, which has won industry recognition,” Hutch said.

Visit SCI and look at Top-Seal for your coal dust control

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.

The plan may be a good one, since attempts to achieve dust control by flooding the lake bed have met with limited success, and flooding – at least this year – may be further hampered by a cutback to California’s 2010 water delivery, limiting the state to 5 percent of the water it has normally been allotted over the past 40-some years.

The solar project is backed by $500 million in funding, which buys a lot of solar panels, but the proposal still has to win the approval of the California State Lands Commission, largely because the DWP wants the commission to waive an environmental impact review.

Another project deterrent may be the designation, by Audubon California this year, of Owens Lake as one of the 17 most important avian sanctuaries in the state, and an emerging “wetland in the making” as bird watchers record the return of record numbers of migrating waterfowl to the partially flooded lake basin.

The DWP has promised to continue flooding at least a portion of Owens Lake to appease these environmentalists, and is in meetings with Inyo County officials, ranchers and residents to win regional support for their proposal.

The response of the former is likely to be guarded; the response of the latter looks largely promising as the state eyes renewable energy resources like solar not only as power sources but badly needed boosts to a failing economy. California is in such dire financial straits that Los Angeles recently raided its recycling initiative fund to balance the budget.

Another plus on the project side is that flooding Owens Lake sufficiently to reduce dust uses enough water to supply 60,000 households. If the DWP plan, which proposes to flood a smaller area than normal for dust control, can salvage even a third of that water, it looks like an environmental win-win.

The DWP proposes starting the solar array with a small test plot, to see if solar panels and migratory waterfowl can coexist, and if a field of solar panels can actually help prevent dust storms.

This pilot project would generate about 50 megawatts by 2012, and save 2,460 acre feet of water per year, or enough to provide for about 4,000 households practicing water conservation measures.
