This paper discusses the use of anion exchange by one treatment facility, Pratt & Whitney (P&W), to remove color, total organic carbon (TOC), and trihalomethane (THM) and haloacetic acid (HAA) precursors to meet the Disinfectants/Disinfection Byproduct Rule (D/DBP) and National Primary and Secondary Drinking Water Regulations (NP/SDWR). The Stage I D/DBP rule regulates non-volatile HAAs as well as THMs, rendering the P&W superchlorination/aeration process infeasible. Using only chloramines as the disinfectant would reduce TOC, THMs and HAAs, but the finished water color would increase to 25 to 35 color units (CU). P&W selected anion exchange to address both the DBP and color issue because it was the most cost effective and least maintenance-intensive means to meet federal regulations. This paper details design considerations tailored for P&W, start-up procedures, and results, which show that color was consistently removed to less than 5 CU and the TOC levels have consistently been reduced by 55 percent or greater. Includes table, figures.
