UV Transmittance 101

Everything You Need to Know about UVT for UV Disinfection

Measurement of UV Transmittance is important for ultraviolet (UV) disinfection of drinking water, wastewater, and process water. Low-pressure UV disinfection systems disinfect water using monochromatic UV light at the 254 nm wavelength. The effectiveness of a UV disinfection system is determined by the dose that the system is able to deliver to the target microorganisms in the water. The effective UV dose is dependent primarily on the combined effects of the UV light intensity, the exposure time, and the water quality or UVT.
