OZONE DOSAGE RATES INTO WATER FLOWS

(GPM x 3.78 x 60 x ppm) / 1,000 = g/hr ozone

Example = (10 GPM x 3.78 x 60 x 2.0 ppm) / 1,000 = 4.536 g/hr ozone dosage

OZONE GENERATOR OUTPUT

((LPM x 60) x 0.001) x g/m3 = g/hr

Example = ((10 LPM x 60) x 0.001) x 10 g/m3 = 6 g/hr ozone production

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)

OZONE CONCENTRATION IN AIR BY WEIGHT

100 g/m3 = 7.8% O3

1% = 12.8 g/m3 O3

1% = 7,284 ppm O3

OZONE CONCENTRATION IN OXYGEN BY VOLUME

100 g/m3 = 6.99% O3

1% = 14.3 g/m3 O3

1% = 6,520 ppm O3

OZONE CONCENTRATION IN WATER

1 mg/l = 1 ppm = 1 g/m3 O3 (by weight)

PHYSICAL PROPERTIES OF OZONE

Density of ozone = 2.14 kg/m3

Molecular weight of ozone = 48

Density of oxygen = 1.43 kg/m3

Molecular weight of oxygen = 32

Density of air = 1.29 kg/m3

Density of water = 1,000 kg/m3
