City of Aurora, Colorado to Purify Drinking Water using Trojan UV

Jul 05, 2006, 01:00 ET from Trojan Technologies Inc.

    LONDON, ON, July 5 /PRNewswire/ - Trojan Technologies Inc. announced
 today that it has been selected to provide an ultraviolet (UV) water
 treatment solution that will increase the City of Aurora's capacity to
 provide pure, clean water to its residents. The planned 50 million gallon
 per day Aurora Reservoir Water Purification Facility (ARWPF), part of the
 Prairie Waters Project, will utilize the TrojanUVPhox(TM) to both disinfect
 and act as a barrier to potentially harmful chemical contaminants in
 drinking water. The value of the contract is in excess of US$10MM.
     "Our customers demand safe, pure water and that is what we promise to
 deliver. UV-oxidation will ensure that we continue that commitment as we
 develop new water resources to provide for our community into the 21st
 century," said Peter Binney, Director of City of Aurora Water.
     "We are excited about the application of this emerging technology as
 part of a multiple barrier purification approach," said Paul Swaim, CH2M
 HILL's Global Technology Leader for Water Treatment. "UV-oxidation offers
 significant benefits that will enhance the protection of public health for
 Aurora's customers."
     The TrojanUVPhox(TM), was selected after a cost-benefit evaluation of
 potential purification approaches was conducted by the project team. Other
 technologies such as ozone were also evaluated. Trojan UV-oxidation was
 selected for its proven ability to provide superior disinfection,
 accomplish treatment without creating disinfection by-products such as
 bromate, and act as a barrier to multiple contaminant classes such as taste
 and odor-causing compounds, pharmaceuticals, steroids, pesticides and
     Marvin DeVries, President of Trojan Technologies, said, "We are excited
 to be partnered with the City of Aurora in providing the UV solution for
 this ground-breaking project. More and more, municipalities are looking to
 address both biological and chemical contaminants. Trojan's two
 environmental contaminant treatment solutions, the TrojanUVPhox(TM) and the
 TrojanUVSwift(TM)ECT, were specifically designed to accomplish treatment of
 environmental contaminants while simultaneously disinfecting. With these
 two product offerings, Trojan is committed to providing customers with the
 ultimate flexibility in selecting a solution that meets their specific
     The TrojanUVPhox(TM) destroys a variety of chemicals including taste
 and odor-causing compounds such as MIB and geosmin, pharmaceuticals such as
 ibuprofen and acetaminophen, hormones such as estrogens and testosterone,
 pesticides such as atrazine and isoproturon, and the emerging contaminant
 class of nitrosamines that include N-nitrosodimethylamine (NDMA) and
 N-nitrosodiethylamine (NDEA).
     All nitrosamines are effectively treated with UV light. Nitrosamines
 cannot be effectively treated with other advanced water treatment
 technologies such as activated carbon, reverse osmosis (RO), or ozone. At
 the federal regulatory level in the U.S., nitrosamines have recently been
 included on the EPA's proposed Unregulated Contaminant Monitoring Rule 2
 (UCMR 2). The State of California has set a Notification Level for NDMA at
 10 parts per trillion and a Public Health Goal of 3 parts per trillion. In
 addition to its ability to destroy these chemicals, UV light treatment
 technologies are increasingly being used as part of a multi-barrier
 disinfection strategy for drinking water facilities because of their
 ability to cost-effectively treat microorganisms that are resistant to
     The TrojanUVPhox(TM) UV-oxidation system at Aurora will add to the
 growing number of installed Trojan UV systems removing chemical
 contaminants and disinfecting using UV-oxidation on a large scale. The
 TrojanUVSwift(TM)ECT UV-oxidation system is being used in other high
 profile drinking water facilities such as the PWN Andijk and Heemskerk
 Treatment plants located in the Netherlands. The TrojanUVPhox(TM) is being
 utilized by a number of plants throughout the world, in both drinking water
 and indirect potable reuse applications, including the California Domestic
 Water Company and the Orange County Water District's Groundwater
 Replenishment System, both located in Southern California.
     Trojan designs, manufactures and sells UV systems for municipal
 wastewater and drinking water, as well as for the industrial, commercial
 and residential markets. The company also provides UV treatment for the
 removal of certain chemicals from water. With over 4,000 municipal
 installations in more than 50 countries using its technology, Trojan has
 the largest installed base of UV systems in the world. Headquartered in
 London, Ontario, Canada, the company also has offices in the U.K., Germany,
 Norway, Spain, and the U.S.
