ABSTRACT
This study focuses on the differences in biodegradation of the natural organic matters (NOMs) of p-hydroxy-benzoic acid (PHBA) and 4-hydroxy-3-methoxy-benzoic acid (VA) with slow sand filter (SSF). The PHBA and VA were biologically transformed into another organic matter in the slow sand filtration (SSF) at the start-up period. The dissolved organic carbon (DOC) of PHBA and VA were stabilized at 2 mg/l after 5th day. The SUVA value of PHBA run decreased with higher sand depth and flow rate, and VA run's increased with higher sand depth, but smaller than PHBA run. Therefore, the PHBA promoted the DBPFP (formation potential of disinfection by products), the VA brought higher biodegradation and lower DBPFP.
