摘要

Orange County Utilities (OCU),Orange County,Florida,embarked on a program to consolidate its threewater treatment plants in their Eastern Regional Service Area and upgrade treatment to provide astabilized water to meet new regulations. Removal of hydrogensulfide by pre-treatment with carbon dioxide to form carbonicacid and air stripping was determined to be the preferredtreatment technology for a new regional plant,the EasternRegional Water Supply Facility. Construction of the facility wasundertaken using the conventional design,bid,build approach. Aheavy hands-on approach by the County and their consultant,Boyle Engineering Corporation,was instrumental in thesuccessful construction and startup of this facility. A core groupof key County,Boyle,and contractor personnel wasinstrumental in the successful startup and operation of thefacility. This approach resulted in the facility meeting the basicgoals and objectives desired by the Orange County WaterDepartment.
