BRINE SOLUTION REMOVES STUBBORN ICE

EXPERIMENTS HAVE SHOWN THAT DRY SODIUM CHLORIDE AND CALCIUM CHLORIDE HAVE NO DIRECT MELTING EFFECT, DEPENDING FOR THEIR EFFECT ON MOISTURE ABSORPTION FROM THE ATMOSPHERE OR THE ICE LAYER. HOWEVER, WHEN THE TEMPERATURE IS NEAR 10 DEG F OR BELOW OR WHEN HUMIDITY IS LOWER THAN 70% THE CHEMICAL GRAINS REMAIN INERT. ACCORDINGLY, NORTH DAKOTA, A STATE THAT IN WINTER EXPERIENCES SEVERE COLD WITH LOW HUMIDITY, HAS BEEN EXPERIMENTING WITH A LIQUID SALTING PROCESS USED SUCCESSFULLY IN ITALY. INITIAL EXPERIMENTS AND FULL SCALE USAGE PROVED SO SUCCESSFUL THAT THE DISTRICT WHERE THE SYSTEM WAS INTRODUCED HAS SWITCHED ENTIRELY. THE ELMENTS OF THE SYSTEM, ALONG WITH DISADVANTAGES AND ADVANTAGES, ARE DISCUSSED.
