A New Look at Disinfection Byproducts in Drinking Water

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

Cryptosporidium and Giardia Inactivation Device

A new water disinfection system has been developed to inactivate Cryptosporidium oocysts and Giardia cysts in drinking water. The technology, known as the CID, inactivates these pathogenic waterborne microorganisms using enhanced ultraviolet (UV) irradiation technology without filtrate disposal, chemical addition or related hazardous by-products.
