UV Disinfection for Drinking Water

Trojan offers the most advanced UV systems in the world for safeguarding drinking water from harmful microorganisms, including Cryptosporidium and Giardia.

UV is a proven and safe alternative for primary disinfection as it is free of the harmful by-products associated with chemical disinfection. UV also has the added benefit of not compromising the taste, color or odor of water.

Trojan has an unrivalled depth of experience at all scales. We are proud to have been selected by New York City to be the supplier of ultraviolet (UV) drinking water disinfection equipment for the Catskill/Delaware UV Disinfection Facility. Trojan supplied 56 units, capable of treating a total of 2.2 billion gallons per day, making this the largest UV drinking water facility in the world. Trojan has also been selected to supply UV equipment for large UV installations in Canada (e.g. Metro Vancouver, Canada) and Europe (e.g. Rotterdam, Netherlands).
New York City's Catskill/Delaware facility is the world's largest UV disinfection system.
Not only are Trojan’s Municipal Drinking Water contracts growing in scope and size, there is increasing diversity in how the innovative UV systems are being integrated with existing chemical disinfection treatments. New government legislation is changing the way communities look at safeguarding their drinking water supplies. Regulations such as the USEPA Long Term 2 Enhanced Surface Water Treatment Rule (requiring the treatment of Cryptosporidium) or the Ground Water Rule (requiring 4-log virus treatment) has increased the use of UV to supplement existing disinfection systems. This treatment strategy is known as “multi-barrier protection.”
UV disinfection provides multiple barrier protection against viruses (e.g. Adenovirus) and chlorine-resistant protozoa (e.g. Cryptosporidium and Giardia)

The USEPA has published the Ultraviolet Disinfection Guidance Manual (USEPA UVDGM 2006) which contains background information on the fundamentals of UV disinfection technology and validation of UV equipment. A number of Trojan's drinking water UV systems have been validated in accordance to the USEPA UVDGM 2006.

Another key consideration is cost. The cost of UV technology is typically about 1/5th that of ozone disinfection and 1/10th the cost of membrane filtration.
