A UV reactor with an annular design, a total liquid volume of 460[emsp4 ]ml, and outfitted with a single lamp with 1690[emsp4 ]mW of germicidal power was tested. Coliphage MS2 was used as a bioactinometer to measure the UV dose at a flow rate of 56.7

Resolving UV photometer outputs with modeled intensity profiles

Autor: Peter F. Roessler, Blaine F. Severin

Publikováno v: Water Research. 32:1718-1724

Photometers are usually reliable indicators of UV intensities in collimated (parallel light source) beams. However, they are not reliable for measuring UV intensity profiles in close proximity to a line source. This is due to both the geometry of lin

Publikováno v: Water Research. 31:574-582

A point-of-use (POU) water treatment system (WTS), comprised of a presed activated carbon block filter followed by an ultraviolet (UV) light reactor, was evaluated for microbial disinfection efficacy following the general guidelines of the United Sta

Contamination of an Unpreserved Semisoft Baked Cookie with a Xerophilic Aspergillus species

Autor: Mary C. Ballenger, Peter F. Roessler

Publikováno v: Journal of Food Protection. 59:1055-1060

An Aspergillus mold was isolated that had contaminated an unpreserved semisoft baked cookie with visible mycelial growth. Due to the xerophilic nature of the contaminating mold, the Aspergillus isolate went undetected using conventional plating media
