RISStandardization of Methods for Fluence (UV Dose) Determination in Bench-Scale UV Experiments
Publisher: American Society of Civil Engineers
Abstract: Ultraviolet (UV) disinfection is now an accepted technology for inactivation of a variety of waterborne pathogens in wastewater and drinking water. However, the techniques used in much of the previous research aimed at ...
Discussion of “Standardized Collimated Beam Testing Protocol for Water∕Wastewater Ultraviolet Disinfection” by Jeff Kuo, Ching-lin Chen, and Margaret Nellor
Publisher: American Society of Civil Engineers
Application of UV Light–Emitting Diodes to Adenovirus in Water
Publisher: American Society of Civil Engineers
Abstract: A ring-shaped disinfection apparatus has been developed containing twenty ultraviolet-light-emitting diodes (UV-LEDs) with emission at 285 nm. The apparatus was applied to Escherichia coli, Qβ, MS2, and adenovirus in ...
Comparison of Hydrogen Peroxide to Ammonium Ions and Sulfite as a Free Chlorine Quenching Agent for Disinfection By-Product Measurement
Publisher: American Society of Civil Engineers
Abstract: Hydrogen peroxide is a potential dechlorinating agent that can preserve chlorinated drinking water samples for the determination of disinfection by-products (DBPs). The impact of hydrogen peroxide on the storage of ...
Improved Method for Real-Time Fluence Monitoring in UV Reactors
Publisher: American Society of Civil Engineers
Abstract: Based on previously developed monitoring system comprising three microfluorescent silica detectors, this paper proposed an improved real-time fluence monitoring method for running ultraviolet (UV) reactors. Adoption of ...
