The design value (DV) for ozone is calculated as an 8-hr average, and the form of the standard is the average of the annual fourth-highest daily maximum 8-hr average ozone concentration at an ambient air quality monitoring site (40 CFR 50.10) averaged …
WebThis value is a calculated value based on ozone concentration and feed-gas flow rate using this conversion: ((LPM x 60) x 0.001) x g/m3 = g/hr. As flow of fed-gas through the ozone generator increases, the g/hr ozone output will normally increase. See example below: Keep in mind, this value only shows overall ozone production.
