The Use of Optimized Pretreatment and UV Disinfection to Comply with Future Regulations

摘要

Clayton County Water Authority (CCWA) owns and operates three surface water production plants (WPP) (J.W. Smith, W.J. Hooper and Freeman Rd.) that supply drinking water to Clayton County, Georgia. CH2M HILL and CCWA are currently developing a strategy to combine optimized coagulation and pretreatment conditions and the use of UV advanced disinfection to comply with DBP Rules,Interim Enhanced Surface Water Treatment Rule (IESWTR) and anticipated Long Term 2 ESWTR requirements. The Plants capacities are 12 mgd at J.W. Smith, 20 mgd at W. J. Hooper, and 10 mgd at the Freeman Rd. Raw water quality is typical for reservoirs in the Southeast except for the Hooper Plant which is subject to wide variations in raw water turbidities.
