Water treatment/ CALCULATOR

UV intensity × exposure time

Show the unit relationship between ultraviolet intensity, exposure time and nominal dose.

A value at the relevant point in the water, not simply lamp electrical power.
Hydraulic exposure time at the stated intensity.
Nominal intensity-time product

40.00 mJ/cm²

A constant local intensity multiplied by time. It is not the validated dose of a reactor. UV transmittance, flow distribution, lamp ageing, fouling, sensor accuracy and reactor validation are excluded.
