What Is Ozone? - ScienceAlert

Ozone is a chemical consisting of three oxygen atoms bonded in a V-like shape. It occurs both naturally through reactions in the atmosphere and as a pollutant released by transport and industrial activities. Yet ozone isn't all bad news. In higher concentrations as a layer far up in the stratosphere ...

DETERMINATION OF OZONE BY ULTRAVIOLET ANALYSIS

The detection limit for ozone is ppm (Code of Federal Regulations, Volume 40, Part , or, in the shortened format used hereafter, 40 CFR ). For reference, the ozone standard in 1996 is ppm, averaged over 1-hour intervals, to be exceeded no more than once per year (40 CFR ). Format and Purpose The sequence of topics covered in this ozone by UV method is different ...

Ozone Concentration and Dosage Equations

20 gpm x l/gal x 60 min/hr. x 2 ppm = 9084 mg/hr. ( gm/hr.) Remember that 9 mg/hr. will permit you to dose the water with 2 ppm of ozone. This does not mean that 2 ppm will be your final dissolved ozone concentration. Due to efficiency losses with injecting ozone and ozone demand of the water, your dissolved ozone concentration will be less.
