Organic carbon concentrations can be reduced by enhanced coagulation, granular activated carbon or membrane filtration, but this fact can also lead to increased in brominated THMs (Black et al, 1996.). A combination of coagulation, ozonation, and biofiltration can effectively reduce trihalomethane and haloacetic acid formation potential (Chaiket et al, 2002.). Natural organic matter (NOM), the main precursor of DBPs, can also be removed by media filters coated with iron oxide | WILEY Wiley Series in Ecological and Applied Microbiology Ralph Mitchell Series Editor WftSTEWATEH MICROBIOLOGY third Edition WASTEWATER MICROBIOLOGY Third .
