文摘

Coagulated water was fractionated according to MW and characterized by 3D-EEM. CTS-treated water presented lower total amounts of DBPs than AC-treated water. The major DBP precursors (low-MW AOM) were largely removed by CTSAC composite. CTSAC enhanced removal of aromatic and aliphatic substances thus reduced NDMA. CTSAC had better performance than AC and CTS in reducing C- and N-DBPs' formation.
