Full Description

The City of Peoria's (City) Greenway Water Treatment Plant (GWTP) applies ozonefollowed by conventional flocculation/sedimentation and biologically active granular activated carbon (GAC) filters intreating its raw water. The GAC filters are used for removing particulates and in assisting inthe removal of disinfection byproduct (DBP) precursors and taste and odor (Tg/L) maximum contaminant level (MCL). By limiting the ozone dose, theCity is not able to maintain ozone residual at ozone contactor or achieve disinfectioncredits with ozone.The City believes that the ozonation and biologically active GAC filtration processes can befurther optimized to improve the removal of DBP precursors and Timproving the removal of total organic carbon (TOC) through the optimizedoperation of ozonation, coagulation and GAC filtration will reduce DBPconcentrations in distribution system, in particular, total trihalomethanes (TTHMs); and,the optimized use of these combined processes will result in improving finishedwater quality in terms of lowering TOC, DBPs and T and,conduct necessary bromate mitigation bench-scale tests and developrecommendations for full-scale consideration. Includes reference, tables, figures.
