DusTreat* DC9140
Wet Dust Suppressant
• Provides control of fugitive emissions while minimiz-
ing moisture addition
• Enhances wetting of dust particles
• Reduces maintenance and housekeeping costs
• Reduces explosion hazard and improves working
conditions
Description and Use
DusTreat* DC9140 is a highly concentrated blend of wet-
ting agents specially formulated to enhance the dust
suppression capabilities of water. This product is de-
signed to increase the ability of water to adhere to and
spread over dust particles. This increases the bulk den-
sity of dust particles and leads to agglomeration, which
prevents particles from being airborne. DusTreat DC9140
solutions are particularly effective in reducing respirable
dust.
Typical Application
Fugitive dust is typically generated during unloading,
stackout, reclaim and crushing operations. These dust
emissions can be a safety hazard, an environmental nui-
sance, and can increase maintenance of material han-
dling equipment. In addition, these emissions can
represent a substantial loss of valuable material.
Conventional wet suppression systems that use water
alone are usually applied in copious amounts at all trans-
fer points. This results in material flow, storage, and
freezing problems downstream. In addition to handling
problems, high moisture reduces the heating value of
coal.
The addition of a small amount of DusTreat DC9140 to
water sprays significantly increases the spray's ability to
wet, allowing less water to be used. DusTreat DC9140
solutions exhibit enhanced residual effects, so that
treatment needs only to be applied at a minimal number
of locations. This reduces the cost of heating value losses
associated with moisture addition to coal.
DusTreat DC9140 solutions should be sprayed at areas
where the dusting material becomes airborne. Typical
application points include rail car or truck unloading ar-
eas, belt transfers, reclaim feeders, and screw feeders.
Treatment And Feeding Requirements
Proper treatment levels for DusTreat DC9140 depend on
many factors, such as severity of the problem, environ-
mental influences, and operating characteristics of the
system. Therefore, this product should be used in accor-
dance with control parameters that GE Water & Process
Technologies establishes for the application.
Maximum efficiency with minimum cost is ensured by
using GE’s Wet Suppression Systems. These systems are
fully automated and custom sized per site specifications
to provide reliable and economical chemical treatment.
While optimum results are obtained with GE equipment,
DusTreat DC9140 can be used in other systems.
For contact with neat (undiluted) product, recommended
materials of construction include stainless steel and PVC.
For dilute aqueous solutions, use of galvanized iron or
brass yields acceptable results.
General Properties

the Material Safety Data Sheet, a copy of which is avail-
able upon request.
Packaging and Storage Information
DusTreat DC9140 is blended as a liquid and is available
through bulk shipment for tank truck quantities. DusTreat
DC9140 should be stored at temperatures above freez-
ing. If freezing occurs, thaw completely and mix thor-
oughly prior to use. To ensure maximum activity, use this
product within six months.
