It takes four times less salt to prevent ice accumulation than to remove ice after it has formed.
What is the average cost savings from switching to brine from rock salt on de-icing process?
67%
At what temperature does brine lose most of its de-icing strength?
20 degrees Fahrenheit
How much rock salt and brine are required to treat 1 acre for de-icing?
Rock salt - 700 lbs
Brine - 100 gallons
Conversion to liquid: 2.288 lbs. of salt = 1 gal. 23.3% brine
Price: 2.288 x $0.04 (rock salt price per lbs.) = $0.0915
Chloride emissions: 2.288 lbs. x 60% chloride = 1.3728 lbs. x 100 gal. = 137.28 lbs.
Cost to treat: 100 gal. x $0.0915 = $9.15
How much did Wisconsin pay per gallon for salt brine?
$12.75/gallon
Paid $37 million for 2.9 million gallons of brine
