PAA And UV Pair Up To Improve Disinfection Performance PAA And UV Pair Up To Improve Disinfection Performance

Peracetic acid (PAA)-based disinfection is growing in the US, both as a standalone disinfection method and in conjunction with other applications such as UV. Water Online Radio sat down with John Maziuk, Technical Development Manager with Solvay Chemicals to understand why.

The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried? The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried?

A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.

UV Disinfection With LEDs UV Disinfection With LEDs

UV LEDs offer the chemical free disinfection of traditional UV while avoiding mercury lamps. In certain applications where customers are concerned about the potential hazards of mercury contamination in the water from a broken lamp, UV LEDs are interesting because they don’t contain any mercury content at all.

ABOUT DRINKING WATER DISINFECTION

WATER DISINFECTION

Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.

Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.

Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
