摘要

- i -PATENT APPLICATION OFEric G. IsacoffandJames W. NeelyforTRIHALOMETHAME PRECURSOR REMOVALUSING ION EXCHANGE EMULSIONSAbstract of the DisclosureTo avoid formation of toxic trihalomethanas indrinking waters disinfected with halogens, these watersare treated with submicroscopic ion exchange resinparticles, optionally in the presenoe of a metal saltcoagulant, to remove the trihalomethane precursorsprior to halogenation.
