UV Dose-Response Behavior of Air-Exposed Microorganisms
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were performed to demonstrate an experimental method for measuring the UV dose-response behavior among air-exposed microorganisms, and to quantify the effect of relative humidity on this behavior. ...
Gamma Irradiation for Inactivation of <i>C. parvum</i><b>, </b><i>E. coli</i><b>, and Coliphage MS-2</b>
Publisher: American Society of Civil Engineers
Abstract: Wastewater and drinking water disinfection are typically achieved via chlorination, ozonation, or UV irradiation. However, there has been increased interest in recent years in alternative disinfectants. This interest came ...
Sequential Inactivation of <i>Bacillus Subtilis</i> Spores with Ultraviolet Radiation and Iodine
Publisher: American Society of Civil Engineers
Abstract: spores were used as an indicator organism to characterize the effects of UV radiation and iodine, alone and in combination, as disinfectants for water. Spore exposures to UV radiation were conducted in shallow, well-mixed ...
UV Pilot Testing: Intensity Distributions and Hydrodynamics
Publisher: American Society of Civil Engineers
Closure to “UV Pilot Testing: Intensity Distributions and Hydrodynamics” by Ernest R. Blatchley III, William L. Wood, and Peter Shuerch
Publisher: American Society of Civil Engineers
Inactivation of <i>Bacillus</i> Spores by Ultraviolet or Gamma Radiation
Publisher: American Society of Civil Engineers
Abstract: spores represent an important bioterrorism agent that can be dispersed in air or water. Existing decontamination practices based on these spores have focused on chemical disinfectants; however, the basic characteristics ...
Effect of UV System Modifications on Disinfection Performance
Publisher: American Society of Civil Engineers
Abstract: Numerical simulations have been performed to gain a better understanding of ultraviolet (UV) disinfection process performance. Similar simulations in previous studies revealed critical paths through which particles moved ...
Dyed Microspheres for Quantification of UV Dose Distributions: Photochemical Reactor Characterization by Lagrangian Actinometry
Publisher: American Society of Civil Engineers
Abstract: Lagrangian actinometry represents a new method of photochemical reactor characterization. The method is based on an application of dyed microspheres, which were developed by attachment of
