Combined Use of Ion Exchange Resins and Granular Activated Carbon for the Controlof Organic Matter and Disinfection By-Products

摘要

The use of anion exchange resin as a pretreatment step to Granular ActivatedCarbon (GAC) is evaluated. Ohio River water and Palm Beach groundwater are used. The results show that resin pretreatment is significant in extending GAC performance. The active component modeling results show that the resins remove the weakly GAC adsorbing compounds but not the strongly adsorbing compounds. Therefore, resin pretreatment does not reduce GAC fouling.
