Verify the inputs
Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.
Water treatment/ CALCULATOR
UV intensity × exposure time
Show the unit relationship between ultraviolet intensity, exposure time and nominal dose.
FROM ESTIMATE TO ACTION
Use the result, not just the number.
Keep the calculation traceable
Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.
Confirm the decision
Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.
Inputs to verify
- UV intensity (mW/cm²)
- A value at the relevant point in the water, not simply lamp electrical power.
- Exposure time (s)
- Hydraulic exposure time at the stated intensity.
