Spectral distribution of uv light during aging of medium pressure UV lamps
As part of a project to validate a UV reactor for disinfection of drinking water, the germicidal output of four medium pressure lamps housed in a continuously operating reactor was followed as a function of time. Spectra were measured monthly and were used in conjunction with radiometer readings to calculate germicidal fluence rates (using DNA absorbance weighting) at the radiometer sensor ...

Computational fluid dynamics modelling of UR–UVGI lamp effectiveness to promote disinfection of airborne microorganisms
This paper focuses on using computational fluid dynamics (CFD) modelling methods to study the effectiveness of upper–room ultraviolet germicidal irradiation (UR–UVGI) lamps in healthcare facilities. This work develops and uses simplifications for boundary conditions in CFD, while details of UR–UVGI lamps and microorganism characteristics were obtained from existing experimental ...

UV Photolysis of Nitrate: Effects of Natural Organic Matter and Dissolved Inorganic Carbon and Implications for UV Water Disinfection
Nitrite (NO2-) formation during ultraviolet (UV) photolysis of nitrate was studied as a function of pH and natural organic matter (NOM) concentration to determine water-quality effects on quantum yields and overall formation potential during UV disinfection of drinking water with polychromatic, medium-pressure (MP) Hg lamps. Quantum yields measured at 228 nm are approximately 2 times higher than ...

What You Need To Know About Hydroxyl Generators
http://www.randrmagonline.com/articles/86169-what-you-need-to-know-about-hydroxyl-generators The main benefit of using a true hydroxyl generator is that they are safe to use in occupied areas for deodorization purposes. Insurance companies do not have to cover a homeowner’s hotels or meals. Business owners do not have to shut down and loose precious business. If people and animals can ...
