Dry Fog™ can effectively suppress the dust at conveyor transfer points, without wetting the material. Unlike dust collection systems, there is no secondary waste stream as we do not collect the dust, but simply "knock down" the airborne dust at the point of creation. Collectors typically deposit concentrated amounts of collected dust back onto the conveyor belt only to create more issues downstream.
DSI has worked on projects that range from low hazard level liquid waste being mixed with dry stabilizers for landfill to nuclear waste remediation projects. These nuclear waste projects include materials being excavated in contained areas to waste volume reduction facilities where contaminated waste is ground up and transferred to long term storage containers.
Dry Fog works by injecting sub-micron water droplets into the air at the point of dust creation. The fog droplets attach to like size airborne dust particles. The slightly wetted particles agglomerate to other particles, adding sufficient mass to settle the dust back into the conveyed product within the covered transfer point.
