The Importance Of UV Transmittance For UV Disinfection Performance

UV disinfection systems disinfect water using UV light to damage the DNA of microorganisms in the water which prevents dangerous pathogens such as cryptosporidium and e-coli from reproducing and causing harm.

UV DISINFECTION DOSE AND UV TRANSMITTANCE (UVT)
The effectiveness of a UV disinfection system is determined by the UV dose that the UV disinfection system is able to deliver to the water. The UV dose is dependent primarily on the combined effects of the UV light intensity, the exposure time of the system and the UV transmittance (UVT) of the water.
