Once the system is configured, it is a simple operation to adjust levels up or down as required. Most operators can tell just by entering the barn if the Ozone levels are too high or too low. If Ozone levels are too high, the generators are simply turned down. The barn environment must be adapted to using Ozone. This is more true in hog operations than poultry .
Hogs are very aware of changes in the environment and are sensitive to change.
Thus, the gradual introduction of Ozone is recommended. You must drop pollution levels gradually and slowly bring up the Ozone levels until the pollution is under control and you are satisfied with the Ozone levels in the barn. This is usually done with a hand-held Ozone monitor checking levels at various locations in the barn. The procedure takes about a week to ten days. At the end of this time, the operator can usually tell if Ozone levels are too high or too low just by walking into the barn.
