AbstractThe effluent of a sewage oxidation pond owned and operated by Pima County, Arizona, and located near Tucson, Arizona, was used to evaluate the feasibility of the use of the ion exchange process for treatment of waters of this type. The oxidation pond effluent was pretreated with alum, settled, and filtered. When Dowex HGR-W and Amberlite XE-258 resins were used in a conventional system, the quality of the effluent water decreased during subsequent cycles as did the original capacity of the system. With the installation of Dowex 11 anion resin ahead of the other two, better quality water was obtained and original capacity of the system retained during successive cycles.
