UVC DOSAGE CALCULATION
Utility to calculate UVC sterilization dose of UV rays. Determine the dose mJ/Cm2 of the UV lamp and estimate its suitability for the water source being used
Input
Input Data | Unit | |
---|---|---|
UV power | W | |
UV flowrate The higher the flow, the lower the UVC dose |
m3/H | |
%UVT (Ultraviolet Transmittance) Fluctuates depending on water quality (refer to the table below), default utility is 100% based on distilled water | % | |
UV light intensity* This intensity is different for each different UV set, requiring a UV meter to determine | mW/Cm2 | |
UVC chamber diameter | M | |
Length of UVC chamber | M | |
Quartz tube diameter | M | |
Quartz tube length | M | |
Number of quartz tubes | M |
Results
Results | Unit | |
---|---|---|
UVC chamber volume | M3 | |
The volume occupied by the quartz tube | M3 | |
Actual volume of water in the UVC chamber | M3 | |
Retention time of water in UVC chamber | S | |
The corresponding UVC dose Please refer to the table below to determine whether this UVC dosage is suitable for the type of water you are using | mJ/Cm2 |
Table to look up the required UVC dosage for different types of water (for reference)
