PRACTICAL APPLICATION OF A COMBINED TREATMENT PROCESS FOR REMOVAL OF RECALCITRANT NOM ? ALUM AND PAC

Three different powdered activated carbons were applied in combination with alum to treat a specific high dissolved organic carbon (DOC) source water with a focus on improving natural organic matter (NOM) removal. Carbon C, a steam activated coal-based carbon, was the most effective carbon for treatment of the source water as treated water trihalomethane formation potential (THM-FP) was reduced.
