different chemicals different seasons

[mack levy]

what are the best chemicals to use in freezing temperatures? Is mag chloride involved? who supplies this stuff?

[PNaida]

We use a calcium chloride solution mixed with our regular chemical. In the urinals we place rock salt. As the users urinate it makes it's own salt brine thus not diluting the calcium chloride in the waste tank. Makes pumping much easier. Pumping poopsicles is not fun. :D
