Validation of a Reactor Containing UV LEDs for the Disinfection of Municipal Drinking Water
Olivier Autin lead research scientist, Typhon Treatment Systems James R. Bolton president, Bolton Photosciences Light-emitting diodes (LEDs) have attracted a great deal of attention in the UV world. The advantages of UV LEDs over traditional mercury lamps are now well established. However, until recently, their low output power has limited them to small-scale, point-of-use … [Read more...] about Validation of a Reactor Containing UV LEDs for the Disinfection of Municipal Drinking Water

Total UV Power from an Irradiance Measurement – Correcting the Keitz Equation
Stephen W. Jaworowicz Process Engineer, Light Sources, Inc. Ultraviolet (UV) lamps are an important part of water treatment plants worldwide. Daily, millions of gallons of water are made safe by using UV to inactivate microbial pathogens. In designing an effective UV water treatment unit, it is necessary to know the total UV power emanating from the lamp. Determining the … [Read more...] about Total UV Power from an Irradiance Measurement – Correcting the Keitz Equation
AOP for Surface Disinfection of Fresh Produce: From Concept to Commercial Reality
Mahdiyeh Hasani Department of Food Science, University of Guelph, Guelph, Ontario, Canada Keith Warriner Department of Food Science, University of Guelph, Guelph, Ontario, Canada The first foodborne illness case linked to fresh produce likely occurred way before the first Caesar salad was prepared back in 1924. However, it was not until the 1970s that incidence of foodborne … [Read more...] about AOP for Surface Disinfection of Fresh Produce: From Concept to Commercial Reality
