Mobile Dust Suppression Keeps Demolition Emissions From Leaving Site

A pioneer in industrial dust control helped a demolition firm contain fugitive dust emissions during the teardown of a 5-story concrete parking deck in a densely populated area. River City Demolition used a self-contained and mobile DustBoss® DB-60 Fusion® manufactured by BossTek to suppress airborne dust created by the jaw processor and falling debris.  The result was adjustable wide-area control of airborne and surface dust that reduced the need for manned hoses and maintained the air quality needed to comply with regulations.

"With occupied buildings on two sides and city streets on the other two, we wanted to find the best method available to suppress the demolition dust and prevent it migration."

From the outset, the planners realized that the downtown location of the parking deck would require dust control beyond the conventional approach of manual spraying with a fire hose.  “With occupied buildings on two sides and city streets on the other two, we wanted to find the best method available to suppress the demolition dust and prevent its migration,” observed Operator/Estimator Josh Runyon.  “We knew our water trucks could help control surface dust on the ground, but our big concern was finding a way to address airborne dust, something that could knock down particles and keep them on-site.”

Because of the close-in location and confined space, River City crews decided to use a jaw processor to pulverize the concrete and take the parking decks down a section at a time.  That helped avoid dust clouds from large sections falling at once, but Runyon stressed the need for containment when he spoke to BossTek Sales Manager Mike Lewis.

“When Josh called us, we had a DustBoss® DB-60 FusionTM on hand, which is one of our larger designs that’s equipped with its own generator for locations without convenient access to power,” Lewis commented.

Once the DB-60 is positioned as needed, it can run unattended all day.

With all components mounted on a road-worthy trailer, the system gave River City crews the versatility to position the fan-driven unit wherever it was needed on a given day.  The water source was a municipal hydrant located nearby, fed by a standard 2-inch (50.1 mm) hose.

The DB-60 Fusion forces water through a circular stainless steel manifold with 30 atomizing spray nozzles, then launches millions of tiny droplets with a powerful 25 HP fan that produces 30,000 CFM (849.50 CMM) of air flow.  Atomized mist droplets of 50 to 200 microns in size are thrown out in a 200 foot (60 meter) cone at an adjustable 0 to 50° elevation angle, capturing airborne dust particles and dragging them to the ground.  Unlike industrial sprinklers used for the same purpose, which can require 500 GPM (1893 LPM) or more of water, the DB-60 uses only ~23 GPM (87 LPM).

The DustBoss® DB-60 Fusion™ is a mobile, self-powered dust suppression system capable of withstanding the harshest job sites.

Rather than have personnel handling hoses to suppress the dust, the single atomized misting unit delivers 62,800 square feet (5,834 square meters) of coverage, while using far less water than hoses and sprinklers, helping contractors avoid over-saturation and run-off.  The unit is paired with a 45 KW gen set featuring a John Deere Tier III Flex engine with a 100-gallon fuel tank, allowing up to 24 hours of runtime.  The efficient diesel engine delivers 480 Volts (60 Hz) with a full load current of 46 amps.

At just 80 inches (2.03 meters) wide, the system can be placed virtually anywhere dust suppression is needed and adjusted based on changes in wind or work activity.  The optional dosing pump is powered from the standard 120V electrical outlet on the gen set, allowing operators to precisely meter surfactants or other additives.  The unit’s versatility makes it suitable for uneven ground, as well as open spaces or tiered terrain.

Water sources can vary, and the unit requires a constant supply pressure of just 10 PSI (.069 BAR).  Standard municipal water pressures are generally around 40-50 PSI (2.76-3.44 BAR).  The water is delivered to the atomized misting unit through a hose with a cam-and-groove quick disconnect coupling leading to the booster pump.  The pump adds approximately 150 PSI (10.34 BAR), with a maximum of 250 PSI (17.23 BAR), depending on the inlet pressure.  For use with a non-potable water source, the Fusion can be equipped with a number of filter options.

The downtown location required dust control beyond manual spraying.

"It was one of the dustiest projects I've ever worked on, but the DustBoss® did a great job. We could locate and aim it perfectly each day, and neighbors seemed pleased with the dust management."
