diseases and ensure water quality from the water treatment plant outlet to the
consumer's tap. ... There is no doubt that chlorine is an effective disinfectant
against most microorganisms and it provides protection in the distribution
network. ... 2011). The removal of DBPs precursors such as natural organic
