“Palatka, FL completed their new 6 MGD potable water facility in the summer of 2009, The system was designed primarily to deal with disinfection byproducts (DBP) control. The City along with assistance from their consultant, Hoyle, Tanner & Associates chose a process of enhanced coagulation and ultrafiltration (UF). An overview of the process and design of the facility is presented. Pilot data is compared with full scale data for the Norit XIGA membranes that were selected and implemented. Issues particular to this facility are discussed including coagulant selection and dosing rate optimization, hydrogen sulfide removal, the importance of pH control, and dealing with variations in feed water quality from the cycling of different wells. Design and performance of the UF backwash recovery system are also highlighted.
