Clayton County Water Authority (Georgia, USA) receives first of three WEDECO UV Systems for multiple drinking water facilities
The WEDECO UV system features three of WEDECO's proprietary K-Series models, two full-time duty and one as a stand by, and is capable of delivering a UV dose that will destroy many pathogenic microorganisms including Cryptosporidium, Giardia, and Legionella. The delivery of this dose will be verified through on-site performance tests. To allow for upgrades including future increases in flow or potentially more stringent disinfection dose requirements, the system is capable of expanding the capacity up to 100% by easily accommodating additional SpektrothermÒ lamp rows.
The Freeman Road plant receives their raw water from reservoirs located in the area. Prior to UV disinfection the water in each plant will be pre-treated using flocculation, sedimentation and filtration processes. Finally, chlorine will be added after the UV to provide a residual disinfectant within the distribution system.
The CCWA Board of Directors decided two years ago to implement advanced disinfection technology in order to provide another level of pathogen protection within its treatment systems. The ultimate goal of the system is to provide clean, safe drinking water to all consumers in the area. Due to the benefits and advantages of UV disinfection the CCWA Board decided to go forward with this technology as an additional microbiological barrier at the W.J. Hooper and J.W. Smith water production plants as well. Disinfection with UV light is a very reliable method to inactivate pathogenic (or harmful) microorganisms. It is equally important for the consumers that the technology does not negatively affect the taste, odor or clarity of the water, nor does it generate any unwanted by-products.
CH2M Hill Inc. was the engineering firm responsible for evaluation and design of the retrofit for all three drinking water production plants.
The WEDECO UV system for CCWA's plants include WEDECO's proprietary SpektrothermÒ UV lamp technology. Developed specifically for high flow rate water disinfection applications, these lamps convert over three times more of the power consumed into useful disinfection energy compared with other available lamp technology (broad band emitting medium pressure lamps).
John Marrino, CEO of WEDECO's North American operation is enthusiastic about the developments in the North American market: "While UV disinfection of drinking water has been common in Europe for some time, it is really just getting started in North America. However, due to the large population and associated water use, we believe it to be fairly obvious that this will quickly become the world's largest market for this application. American and Canadian communities are now moving rapidly to implement UV technology to ensure the quality and safety of the water they deliver to their consumers." Mr. Marrino added, "We are pleased to have completed one phase of the Clayton County Water Authority project and look forward to delivering the remainder of the systems for the two additional plants. Our long-term commitment to developing more efficient, reliable and environmentally friendly ultraviolet water treatment technologies is a major reason for our current lead in the marketplace."
