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)
