The benefits of ultraviolet (UV) light in destroying waterborne diseases are well established. This article (part one in a continuing series) will focus on explaining the basic terminology associated with the technology.
Understanding Ultraviolet Terminology
This article offers a method for comparing the results of a UV pilot system with a full-scale UV system.
These profiles of various disinfection processes can help managers decide which process is best suited for their treatment plant.
Managers of water treatment plants must be able to choose the right disinfection system to bring their plants into compliance with government regulations.
The application of disinfectants in drinking water treatment for controlling microbial quality has drawbacks. These include the formation of potentially harmful disinfection byproducts (DBPs) that can be potential carcinogens (e.g., trihalomethanes [THMs] when chlorine is used as a disinfectant). The general equation is:
ÊÊÊNOM + Disinfectant -> DBP
ÊÊÊWhere NOM = Natural Organic Matter
As consumer awareness grows in regard to the quality of water consumed every day from the numerous well water systems across America, the process that is gaining the most attention is that of disinfection.
The process of reusing wastewater for sprinkling at the Sugar Hill Golf Course in Gwinnett County, Georgia, was time consuming, costly and problematic. An in-line ultraviolet disinfection unit installed at the treatment plant solved the problem.
