The Ultraviolet Spectrum
Understanding Ultraviolet Light
Categories of UV Light
![Page 6: Uv Pure Overview Mar 2011](https://reader036.fdocuments.net/reader036/viewer/2022062514/5590ee6c1a28ab0a748b477f/html5/thumbnails/6.jpg)
How UV disinfection works
DNA Replication
UV light instantly alters the DNA of pathogens rendering them unable to reproduce (sterile)
![Page 7: Uv Pure Overview Mar 2011](https://reader036.fdocuments.net/reader036/viewer/2022062514/5590ee6c1a28ab0a748b477f/html5/thumbnails/7.jpg)
UV Dose is the product of :
Intensity X Residence Time
(Quantity of UV Light per (Contact Time in UV Reactor)
unit Area Falling on a Surface)
UV Dose is expressed in mJ/cm2 (Millijoules per centimeter square)
mWsec/cm2 (Milliwatt second per centimeter square)
μWsec/cm2 (Microwatt second per centimeter square)
UV Dose Calculation
![Page 8: Uv Pure Overview Mar 2011](https://reader036.fdocuments.net/reader036/viewer/2022062514/5590ee6c1a28ab0a748b477f/html5/thumbnails/8.jpg)
Factors Influencing UV Dose
• Water Quality Factors– UV Transmittance (UVT)– Turbidity– Hardness & Water Chemistry – Quartz Sleeve Fouling
• Flow Rate– Faster Flow means decrease in UV Dose– Slower Flow means increase in UV Dose
• Lamp Age and Operating Temperature– UV Lamps lose output (UVI) over time– UV Lamps lose output outside optimal operating temp range
![Page 9: Uv Pure Overview Mar 2011](https://reader036.fdocuments.net/reader036/viewer/2022062514/5590ee6c1a28ab0a748b477f/html5/thumbnails/9.jpg)
Water UV Transmittance (%UVT)
• The amount of UV light from a UV lamp that can transmit through a sample of water – usually reported for a path length of 1 cm.
• UVT is expressed in percentage value, %UVT • The higher the %UVT- the more UV Light transmitted through water
Distilled water = 99 %UVT
Tap Water = 85-95% UVT

Turbidity (NTU)
• Turbidity is a measure of Suspended Solids in the water
• It is expressed in Nephelometric Turbidity Units (NTU)
• Turbidity levels over 1 NTU
can shield microorganisms
from the UV lights,
making the UV disinfection
less effective
![Page 11: Uv Pure Overview Mar 2011](https://reader036.fdocuments.net/reader036/viewer/2022062514/5590ee6c1a28ab0a748b477f/html5/thumbnails/11.jpg)
Hardness & Iron
• High level of Hardness and Iron can contribute to significant
Fouling and Scaling of Quartz Sleeve which in terms lowers the UV Transmittance affecting the overall disinfection performance
• Cleaning Mechanism is therefore necessary to eliminate the Fouling/Scaling problem
