- •
PM oxidation and PAC adsorption both improved the removal of DOC and DON compounds.
- •
PM oxidation has better performance on reducing HAA formation than PM adsorption.
- •
PAC adsorption has better performance on reducing N-DBP and THM formation than PM oxidation.
- •
PM improved the performance of PAC on removal of C-DBP and N-DBP precursors.
- •
PM–PAC process is a promising pretreatment technology in integrated control of DBPs.
