This study evaluated the formation and removal of DBPs along with precursors in a pilot-scale treatment plant employing conventional treatment processes (coagulation/ sedimentation/filtration), ozonation and granular activated carbon (GAC) treatment with three EBCT (10min, 15min, 20min) and the type of three GACs (coal-based F400, coal-based SLC, coconut-based SLC-2000). Pilot-scale study suggested that GAC adsorber demanded more than EBCT 15min for DBPs removal and exhibited excellent performance for HAA removal. During approximate one year pilot scale evaluation for ozone/GAC processes, as high efficiency of removal was continued, exchange cycle and regeneration life of GAC need to be decided through longer operation. |
