Ohio WTP to improve water treatment with new UV disinfection system
BEAVER DAM, WI, Feb. 18, 2014 -- The Dr. Dimiter Ramandanoff Water Treatment Plant (WTP) in the city of Berea, Ohio, will soon receive new UV treatment systems from Engineered Treatment Systems (ETS), a manufacturer of UV disinfection systems and a wholly-owned subsidiary of Neptune-Benson, to better disinfect its drinking water. The UV disinfection system will consist of two ETS SX-425-10 drinking water reactors, each installed after the carbon-based filtration system, capable of treating up to 3.6MGD peak flow for a transmittance of 84 percent. UV disinfection was chosen because it is the single, most effective treatment against bacteria, viruses and Cryptosporidium. In 2010, the Dr. Dimiter Ramandanoff WTP installed a new carbon-based filtration system as well as a new backup storage tank. Despite these improvements, water from the tap was periodically discolored. As such, an initiative to replace the aging cast-iron water lines was launched, and the decision to add UV disinfection to further improve the water quality was made.The ETS-UV disinfection was selected because all ETS UV systems are third-party validated in accordance with Environmental Protection Agency's (EPA) Guidance manual and are manufactured at the ETS production facility in Beaver Dam, Wis. In addition, the city carefully examined a variety of disinfection methods, and UV was selected as the most cost advantageous because of its simplicity, reliability and economical operating costs. Berea is a western suburb of Cleveland which serves a population of approximately 20,000 people. The drinking water plant is fed by the east branch of the Rocky River. Water can also be drawn at times from Coe Lake and Baldwin Creek if needed.
