Fact Sheet
DusTreat* DC9123
Residual Foaming Agent
 Provides residual control of fugitive emissions
while minimizing moisture addition
 Produces quality foam with most plant waters
 Maintains control of emissions through multiple
transfer points and active storage piles
 Effective on western subbituminous coals and
mineral ores
 Environmentally safe
Description and Use
DusTreat* DC9123 is a concentrated dust control
foam and binding agent formulated to control fugi-
tive dust throughout the plant material handling
system. In addition, it controls dust on active stor-
age piles and during reclaim operations.
DusTreat DC9123 is mixed with regulated volumes
of water and air, then passed through a foaming
chemical chamber to produce Ultrafoam. The Ultra-
foam bubbles collapse upon impact with dust par-
ticulate, encapsulating each particle in a blanket of
moisture. The binding agent polymerizes on the sur-
face to entrap the coal fines in a microscopic, plas-
tic film. This provides long term dust control even
after the moisture dries out.
Use of this product for dust control is covered by
U.S. Patent 5,194,174 and other foreign patents.
Typical Application
Fugitive dust is typically generated during unload-
ing, stackout, reclaim, and crushing operations.
These dust emissions can be a safety hazard, an
environmental nuisance, and can increase mainte-
nance of material handling equipment. In addition,
fugitive dust emissions can represent a substantial
loss of valuable fuel.
DusTreat DC9123 offers the best available technol-
ogy by providing a foamable binder. It minimizes
moisture addition while providing residual effects,
and this eliminates the need to apply treatment at
all locations. DusTreat DC9123 is a convenient and
cost-effective alternative to the multi-application
approach typical in most water spray systems. Use
of DusTreat DC9123 can reduce the heating value
loss associated with moisture addition to coal by
applying up to 90% less moisture than most wet
suppression systems.
Treatment and Feeding Requirements
DusTreat DC9123 should be applied directly to a
dusting material at the impact point. Typical appli-
cation points include downstream of the unloading
area, belt transfers, and at crushers and breakers
where new dust is generated.
DusTreat DC9123 should be fed directly from a
closed (vented) shipping container to minimize at-
mospheric contact. For consistent optimum per-
formance, use a chemical pump designed to handle
high viscosity materials. The suction piping should
be enlarged to a 1 inch (25.4 mm) minimum. Rec-
ommended materials of construction include stain-
less steels and most plastics for contact with the
neat (undiluted) product. Carbon steel is not com-
patible with this product.
