The formation and control of disinfection by-products by two-step chlorination for sewage effluent: Role of organic chloramine decomposition among molecular weight fractions

•Two-step chlorination formed less DBPs than one-step for wastewater effluent.•Decomposition of organic chloramines was responsible for the lower HAN formation.•High and medium MW DON tend to form organic chloramines during first chlorination.•The low MW DON were the predominate precursors of decomp...
