Other parameters used to define UV susceptibility include the Z value or Z eff (same as UV rate constant), the inactivation cross-section, the D 90 (UV dose to inactivate 90%), and variations of Cited by: 2. In addition, the intensity at each wavelength in the germicidal range and the germicidal effectiveness at the associated UV wavelengths are also considered because microorganisms absorb different amounts of UV light at different wavelengths.

Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink. UV-LEDs have proven to be at least as effective as low-pressure UV (LPUV) lamps for water disinfection across a wide range of germicidal wavelengths (e.g., – nm) [8,9,10,11].However, the wide-scale implementation of UV-LED water disinfection technology has been restricted by high capital costs, low output power and low wall-plug efficiency Author: Peter Jarvis, Olivier Autin, Emma Harriet Goslan, Francis Hassard.

The disinfection effect of pulsed light is primarily due to the UV content and can be modeled using the same basic UV rate constants previously presented for UV exposure. One exception exists – pulsed light Cited by: 6. The germicidal effects of UV-C radiation have been known for a long time.
