Rock Salt vs Liquid Brine with Phill Sexton

Phill Sexton with WIT Advisers will describe the different effects liquid brine and rock salt have when used for snow and ice control. Phill will discuss how you can be more efficient and save yourself time and money.

Let’s put a bit of science in to practice here on what we’re talking about with liquids. To keep it simple, that solid rock salt that we’re using now doesn’t do anything for us until it converts to a brine. That brine is the liquid form of the traditional salt that we use in the industry (sodium chloride).

There are others that we use like magnesium chloride and calcium chloride. When we think about converting that solid rock salt to a liquid, why would we want to get to a liquid quicker? So it’s all about moisture. Rather than wait for the solid salt to react to moisture

 

That moisture comes from either...

  • Precipitation in storm
  • Moisture in the air

 

If it’s grabbing moisture from the air the conversion time is going to take that much longer versus having that instant reaction with the liquid.

 

What that liquid is doing if it’s sodium chloride is depressing the freeze point of water at the surface so the water will actually freeze below the 32° F mark now usually at around 20° is that practical effectiveness of sodium chloride brine

 

With calcium chloride or magnesium chloride, that actually creates an EXOTHERMIC EFFECT versus the sodium chloride brine, that’s actually creating an ENDOTHERMIC EFFECT but in either case they must be in their liquid form.

 

So in order to achieve the goal of having this concept of using liquids as a no-brainer.

 

I think it’s really important to state clearly WITH LIQUIDS YOU’RE ACHIEVING THE SAME RESULT BUT A LOT QUICKER.

 

So the way that salt works is SOLID SALT DOES NOTHING UNTIL IT CONVERTS TO A LIQUID BRINE.

 

That’s what’s in the tank (liquid brine).

 

That’s the opportunity we have... rather than wait a period of time for that conversion to happen we are essentially removing a step or two in the process to get directly to the result which is coming out of these spray tips.

 

So think about solid salt coming out of this green tip. It’s just in a much more concentrated form and it’s going exactly where you need it to go. It just happens to be liquid, but it’s the same exact thing. Make sense? Instead of it going this way (outwards) it’s going this way (down).
