The purpose of this study is to investigate the effect of the coagulation hindrance of extracellular organic matter (EOM) and intracellular organic matter (IOM) from the algae cell destroyed by pre-chlorination. Consequently, DOC produced by chlorination rapidly increases and becomes maximum about 20 minutes. The increase of DOC means Products of IOM from the destroyed cell of Chlorella sp. The DOC matter under chlorination increases from 1.3 to 2.5 times larger than that of non-chlorination at each fraction number of gel-chromatogram. The turbidity, DOC removal under chlorination decreases comparing with non-chlorination. From the results of the pH titration and jar tests, IOM produced by pre-chlorination makes the formation of alum-organic matter complexes as well as EOM and does not neglect the effects on coagulation process. The influence on alum-organic matter complexes formation is dependent on the molecular weight size of organic matter.
