Ice Melt, De-Icing & Dust Control
Products
Q: Vegetation surrounding areas that I’ve treated with ice
melt is dead or browning. What can I do to prevent this?
A: The main cause of dead or browning plants is over application of ice
melting compounds. When the ice and snow starts melting the liquid brine can run off onto lawns and nearby vegetation causing this problem if ice
melters are over applied, especially ice melters with high chloride content. Be sure to apply ice melters as is recommended on the bag to prevent
this problem.
Q: Product residue is tracking into my home or building.
A: Ice melt is probably being
over-applied. Read and follow application rates as given on the bag to eliminate excessive ice melter residue being carried into homes and office
buildings. Throw mats at the entrances of buildings are recommended during winter months for additional protection from carrying residue into the
building.
Q: I recently had new concrete walks and driveways poured at my facility. I’ve heard that ice melt products may
damage new concrete.
A: Concrete requires a minimum of one year to fully cure before any ice melt product is applied. The
freeze/thaw cycles that occur in winter are stressful if the concrete has not been properly formulated, finished and cured by standards required by the
American Concrete Institute. During that first year, traction aides such as sand can be used in place of ice melt.
Q: Why is
dust control important?
A: A dusty road surface is a deteriorating surface. Once the fine material is lost, the aggregate in
the paved surface follows, resulting in ruts and potholes that require costly spot repairs. Calcium chloride or magnesium chloride is spread on
dirt road surfaces and constructions site roads for road stability by drawing moisture from the air to help compaction of the road surface and keep dust
under control.
Q: What are liquid de-icers and how are they used?
A: Liquid ice-melters are frequently used for
several purposes: 1) Anti-icing-where the liquid is applied to the pavement before an event to prevent the formation of an ice-pavement bond, 2) De-icing
– the liquid is applied to the surface area after mechanical removal of ice and snow has been completed, and 3) Pre-wetting-where liquid is
used to prewet solid chloride de-icers to reduce scatter, initiate brine formation, and/or lower the effective temperature of the solid de-icer.
Liquid ice-melters come in a variety of forms and are used in many different applications. Contact your sales representative to find out if they
are right for you.
Q: What is magnesium hydroxide slurry?
A: Magnesium hydroxide slurry is a non-hazardous chemical that is used in wastewater treatment to provide alkalinity and pH
adjustment, among other benefits. It is the same chemical as in Milk of Magnesia, only much more concentrated. It provides more alkalinity
than sodium hydroxide or soda ash, at a lower cost. Its cost stability, safety, and performance enhancements over lime and sodium-based products
are making magnesium hydroxide the chemical of choice for many wastewater plants.
Q: What
kind of “performance enhancements” does magnesium hydroxide provide?
A:
Magnesium hydroxide offers benefits from the collection system through filter press. Under the tradename ThioguardTM, magnesium hydroxide is used
to control sulfide odors, corrosion, and grease build up in the collection system. Once at the plant, magnesium hydroxide can continue to provide
odor control while providing the necessary alkalinity and a stable pH for the nitrification process. Magnesium is also a micronutrient that helps
stimulate biological activity and enhance biological phosphate uptake. As a divalent ion, magnesium helps improve settling and sludge dewatering,
reducing sludge disposal costs and saving energy for those plants incinerating their sludge. Coburn Chemicals will provide a system assessment to
determine the best feed point(s) for magnesium hydroxide slurry and identify how it can improve your plant’s performance.
Q: Can I put magnesium hydroxide slurry in my caustic tank?
A:
No. Magnesium hydroxide slurry requires special tank configuration and pumping to ensure its successful application. Most magnesium hydroxide
tank systems contain baffles, mixers and use peristaltic pumps to feed the product. A site assessment and system overview is critical to the successful
implementation of magnesium hydroxide slurry. Coburn Chemicals provides trial, skid-mounted feed systems for its customers. During the
trial, we will determine optimal feed rates, plant benefits, and help determine optimal feed system for permanent application.
Q: Do you offer any alternatives to methanol?
A: Coburn Chemicals is currently evaluating several non-hazardous products for use as a methanol replacement. Please contact us
for the most up-to-date information regarding these developments.
