Ozone Dosage Calculations:

Standard Calculation Grams Per Hour to Parts Per Million
grams per hour / gpm X 4.41 = ppm or mg/L

Standard Calculation Ozone Dosage to Grams Per Hour
dose X gpm (mg/L) X 0.012 = ppd ( X 19 = g/h )

Metric Calculation - Ozone Dosage to Grams Per Hour
dose X m3/h (mg/L) = g/h

Standard Calculation - Grams Per Hour to Ozone Dosage
g/h /19/0.012/gpm = dose (mg/L)

Metric Calculation - Grams Per Hour to Ozone Dosage
g/h /m3/h = dose (mg/L)

Standard Calculation - To Find Ozone Gas (Grams Per Hour)
SCFH X w% X 0.34 = g/h

UV Germicidal Dosage Calculation:

intensity (microwatts) X exposure time (seconds) = microwatts dose area (cm2)

1 m3/h = 1000 liters/hour or 264.5 gallons/hour

Measuring Flux across a Membrane

Flux = Flow rate / membrane area

Unit of flux = LMH
