UV Dosage for Disinfection: Six Steps- Understanding of dose disinfection ,Viruses, bacteria, mold, and other pathogens are now stopped dead in their tracks with XtraLight's UV-C High Power Ultraviolet Disinfection System. Follow these steps when using this effective and powerful light which emits 254 nm wavelengths. The results will ...Yikes! What the UVDGM Does Not Address on UV Disinfection14 17 2 t page 13 does not provide details on the action spectra and lamp output used to determine this ratio, the 2003 draft UVDGM did (EPA 815-D-03-007). This ratio was determined using the MS2 action spectra from 225 to 320 nm as shown in Figure F.9 of



Understanding UV Dose - Aquatell

UV dose is a very important, yet often poorly understood concept with residential UV system consumers. The UV dose that is applied by any UV system is critical in understanding the level of protection that will be offered by the UV system. UV dose is the measure ...

New EPA Rule to Drive use of UV Disinfection | WaterWorld

A UV dose of 40 mJ/cm2, recognized by the UV industry as providing 4 log inactivation for a wide range of waterborne pathogens, is recommended for providing multi-barrier disinfection using UV light. UV light combined with hydrogen peroxide is an emerging approach for disinfection and control of taste and odor and micro-pollutants.

How to Calculate UV-C Dose on a Surface | ProLampSales

When UV-C fixtures or handheld devices are used to sanitize surfaces and objects, it may be useful to determine the UV dose applied and comparing that to tables of dose requirements for deactivating microorganisms. Measure UV Intensity To get accurate dose data you need to start with a UV-C detector. The detector needs to display an intensity reading measured in microwatts per square ...
