Description
Ultraviolet (UV) disinfection is quickly gaining momentum as a viable method for disinfection of potable water. The U.S. Environmental Protection Agency (EPA) has expressed their belief that UV disinfection is an “available and feasible” technology, and plans to publish a draft guidance document on UV disinfection later this spring/summer. Research has indicated that relatively low doses of UV disinfection have proven to be very effective for Cryptosporidium and Giardia inactivation. The success of the technology, coupled with pending drinking water regulations that are more stringent, has prompted many water utilities to investigate UV as a primary barrier to these pathogens. Several utilities are already moving forward with the implementation of UV disinfection systems. Because the interest in UV technology has developed quite rapidly, manyquestions still remain regarding the design and operation of UV systems for potable water treatment. Many utilities are unclear as to how UV disinfection should fit into their overall disinfection strategy, and whether or not it is an appropriate technology for their system. This paper discusses the theory behind UV disinfection and addresses the question of how UV disinfection “fits” into plants. Design considerations are examined and an UV disinfection case study at Poughkeepsie, New York is presented. Includes 7 references, table, figures.
