This study evaluates 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 (10 min, 15 min, 20 min) and three types of GACs (coal-based F400, coal-based SLC, coconut-based SLC-2000). Pilot-scale study suggested that the GAC adsorber demanded more than EBCT 15 min for DBPs removal and exhibited excellent performance for HAA removal. During approximate a 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.
