Storing Chlorine Dioxide Solution
I had a question about storing chlorine dioxide solution. You recall that this solution may be used to disinfect both calf feeding equipment and calf pens. [Usually stronger solution for pens.]
The solution starts to degrade (weaken, go down in ppm) as soon as it is created. Ideally, the dairy makes up the solution and uses it right away.
On the other hand, it may not be practical to use all of it at one time. Therefor, our goal is to slow down this process. Warm temperatures and exposure to air speed up this process. Using a 20L pail in our clinic garage without a lid at 18C our solution went from about 500ppm to 50 ppm in 5 days.
A one of our clients, however, uses a 15 gallon chemical barrel for chlorine dioxide solution storage. (see picture below). It has a tight screw plug that virtually eliminates air movement. Right now they are getting two weeks storage with less than 100 ppm losses.
