Ozone dosage rates into water flows
Calculate ozone dosage rates into water based on your water flow rate (GPM) and desired ozone dosage rate (ppm) to
determine the required ozone production rate for your system (g/hr)
(GPM x 3.78 x 60 x ppm) / 1,000 = g/hr ozone
This provides ozone dosage rates into water. Actual dissolved ozone levels in water will be different as no ozone
system is 100% efficient at dissolving and keeping ozone in water.
Ozone Dosage Rate Calculator
Calculate ozone dosage rates into water based on your water flow
rate (GPM) and ozone generator output (g/hr) to determine the dosage rate of water achieved with your water flow
rate and ozone generator.
(g/hr x 1,000) / (GPM x 3.78 x 60) = ppm
This provides ozone dosage rates into water. Actual dissolved
ozone levels in water will be different as no ozone system is 100% efficient at dissolving and keeping ozone in
Ozone Generator Output Calculators:
Calculate ozone output from LPM and g/m3 ozone concentration)
((LPM x 60) x 0.001) x g/m3 = g/hr
This calculation works the same regardless of feed-gas type (air or oxygen) as a mass (grams) is used in the
calculation, therefore it is a direct calculation.
Calculate ozone output from LPM and % by weight, Oxygen
((LPM x 0.001) x 60) x (14.3 x % by weight)
This calculates ozone output in g/hr when using oxygen feed-gas and % by weight ozone concentration.
Calculate ozone output from LPM and % by weight, Air
((LPM x 0.001) x 60) x (12.8 x % by weight)
This calculates ozone output in g/hr when using dry-air feed-gas and % by weight ozone concentration.
Common ozone unit of measure calculators:
Convert common ozone output units
lb/day = pounts per day
g/hr = grams per hour
mg/hr = milligrams per hour
kg/hr = killograms/hour
Ozone Concentration in air by volume
1 mg/l = 1 g/m3 = 1 ug/ml = 467 ppm O3
1 ppm = 2.14 mg/m3 O3
100 pphm (parts per hundred million = 1 ppm (parts per million)
This calculator is only used for ozone concentrations values by volume. See below for
by weight conversions.
Ozone Concentration in air by weight
100 g/m3 = 7.8% O3
1% = 12.8 g/m3 O3
1% = 7,284 ppm O3
This calculator is used for converting ozone concentration units when ozone is measured in air. For oxygen use the
Ozone Concentration in oxygen by weight
100 g/m3 = 6.99% O3
1% = 14.3 g/m3 O3
1% = 6,520 ppm O3
This calculaotr is used for converting ozone concentration units when ozone is measured in oxygen. For air, use the
Pressure and Flow Calculators:
Convert common flow values
SCFH = Standard Cubic Feet per Hour
LPM = Liters per Minute
GPM = Gallons per Minute
m3/hr = Cubic Meters per Hour
Corrected pressure for pressurized flow meter
Corrected Flow = Measured flow X
√ (PSI +14.7) / 14.7
Calculate pressure in your float style flow-meter using this calculation. When flow-meters are under pressure the
flow must be calculated for the pressure to provide accurate flow readings.
Convert any pressure value by entering value in the blank and pressing Convert.
