Ozone Formulas

Flow Rate and Desired PPM Conversion in Water

Use this calculation to determine the necessary ozone production to achieve a specific ozone dosage into a water flow.

(3.78 * 60 * GPM * PPM) / 1000 = g/hr.

Output of an Ozone Generator using Oxygen Feed-gas

Use this calculation to determine the output of an ozone generator on oxygen feed gas. Enter the standardized flow rate of oxygen and the concentration of ozone to determine the production of your ozone generator. This calculation only works with oxygen feed gas.

SLPM * 0.001 * 60 * 14.3 * %O₃ = g/hr.

Output of an Ozone Generator using Dry Air Feed-gas

Use this calculation to determine the output of an ozone generator on dry air feed gas. Enter the standardized flow rate and the concentration of ozone in this dry air to easily determine the production of your ozone generator! This calculation only works with dry air feed gas.

SLPM * 0.001 * 60 * 12.8 * %O₃ = g/hr.

Output of an Ozone Generator from g/m³ of Ozone

Use this calculation to determine the output of an ozone generator when you know the flow rate and ozone concentration in grams of ozone per m³ of air/oxygen. This calculation removes the question of what type of feed gas is being used and can be used with either dry air or oxygen.

SLPM * 60 * 0.001 * g/m³ = g/hr.

Output of an Ozone Generator from PPM of Ozone & Flow Rate

Use this calculation to determine the output of a commercial ozone generator. If you do not know the flow rate it can be measured with a wind speed meter and calculated. Using the air flow rate in CFM and the ozone level in PPM the output of the ozone generator in mg/hr can be determined. This calculation can also be used to determine the amount of ozone necessary to treat a flue gas stream or many other industrial emission control applications.

CFM / 35.33569 * 60 * PPM * 2.14 = mg/hr.
