摘要

•Trends in THM formation over 18months and across 35 membrane plants analysed.•Literature THM yield data predominantly in the 25–50μg tTHMs per mg DOC range.•Study revealed average yields of 10–70μg THMs/mg DOC for mean DOC passage of 18%.•Increased bromine substitution lead to slightly reduced total THM concentrations.•THM mitigation best addressed by limiting permeate DOC concentration to <1.1mg/L.
