Effective Waste Water Disinfection with UVC Technology

Currently more than twenty percent of wastewater treatment plants in North America use UVC light technology.  While the number of waste water treatment plants using chlorine disinfection is higher, UVC light disinfection is more often the choice for new facilities being built worldwide.  To make the decision more clear-cut, the costs of UVC systems over the last several decades has decreased to make it much more competitive with chlorine systems.  This is due in part to a huge improvement in lamp and system designs as well as the reliability of these systems. 

The biggest advantage to UVC is that it is a more environmentally-friendly technology and does not produce dangerous by-products that can get into the environment.  UVC systems also typically cost less to maintain and are the most effective way to deal with chlorine resistant protozoa such as Cryptosporidium and Giardia.  The safety of the system helps municipalities comply with strict federal and local standards for public safety and environmental protection. In chlorine disinfection systems, the chlorination of residual organic material can generate chlorinated-organic compounds that can be cacogenic and harmful to the environment.   

A UVC disinfection system uses either low-pressure or medium-pressure mercury arc lamps, a reactor, and ballasts. To effectively inactivate micro-organisms, the optimum wavelengths of the UVC lamps need to be in the range of 250 to 270 nm.  Also when setting up a system careful planning is required as the intensity of the radiation is affected by the distance of the lamps to the material to be disinfected.
