Dust Solutions Incorporated (DSI) is a leading manufacture of  Dust Suppression Systems for the Power Generation, Mining, Mineral Processing, Aggregate, Pulp & Paper, Wood Products, Hazardous Waste, Marine and Bulk Handling industries. We offer the following types of dust suppression-dust control systems.

Dry Fog Agglomerative Dust Suppression Systems

dry_fog_ex_1Our technology uses a very special type air-atomizing nozzle that produces a very dry fog (water droplets 10 microns or smaller) to agglomerate and remove airborne dust particles (PM-10) from various material handling and processing operations. It is our primary product and our specialty. D.S.I. dry fog systems have proven to significantly reduce fugitive dust from a variety of material handling points. These include truck dumps, rail dumps; reclaim tunnels, crushers, screens, stack outs, ship loaders, and truck loading silos and conveyor transfer points.

There are many advantages to our system, including, ease of installation, simplified maintenance, and flexible system configuration. The overall capital investment, operating cost and system performance is superior to ventilation, conventional water spray, and chemical injection type systems. These advantages are due in part to the fact that we use easy to install, pre-assembled components, housed in protective enclosures. Individual nozzle mounts are used in most applications for optimum nozzle placement. We supply all components for complete systems including air compressors, air receiver stations, pumps, filters, pressure regulating modules, nozzles, and supply lines.

Wind Fence and Wind Screen Systems.

Wind Fence Systems are often used in conjunction with fogging as a way to help control and contain dust around open dump points. They are also used as a stand-alone system to reduce wind velocities around stockpiles and stack out operations. Wind reductions of 75% or more can be realized by the use of this unique knitted polyester material and its use can offer a significant savings over construction of storage buildings.We supply the windscreen fabric, standoff brackets, and attachment hardware.

Hydraulic Water Spray Dust Suppression Systems

Sometimes it is desirable to wet the process material by direct application of water onto the process material. These type of systems are used at locations such as conveyor stack outs to storage piles, and in processes where wetting the process material is not a problem. Some systems are equipped with modulating water regulators that are programmed to maintain the proper ratio of material process flow to water. We supply all of the necessary components including filters, pressure pumps, distribution modules, pressure regulation modules; electrical control modules supply lines, nozzle manifolds and nozzles.

Sales Area

We offer our products and services worldwide. DSI maintains two offices in the United States: Vancouver, Washington (Sales & Service) and Beaufort, South Carolina (Headquarters for Engineering, Manufacturing and Service).

 

Coal_Conveyors_260Dry Fog™ systems utilize compressed air and plain water to produce a very dry fog (1-10 micron droplet size). These ultra-fine water droplets attach (agglomerate) to like size dust particles, particulate matter 10 microns or smaller (PM-10). The slightly wetted dust particles are then heavy enough to be removed from the air by their added weight and fall back into the process. It is important to note, we only wet the dust, not the material, resulting in low water consumption and no significant wetting of the product (typically less than 0.05 % by weight). This is the driest form of dust suppression available. See Moisture Comparison Chart

The Environmental Protection Agency (EPA) has ruled that fogging systems are "Best Demonstrated Technology"  alt see EPA New Rules for handling Sub-bituminous Coal and Lignite. In the Powder River Basin most of the PRB Coal Mines have switched to fogging system as a safe, cost effective way to comply with air quality and fire safety regulations and issues  See PRB Coal Mine Testimony to EPA
