The main objective of this paper is to reveal the water quality evaluation techniques from the view points of Triharomethane formation of natural waters which are utilized for public water supply.
The major results are followings.
(1) The different fractionated components which are classified on the basis of molecular weight show different THM formation potentials.
(2) The THM formation potentials of the treated water by coagulation, activated carbon adsorption and ozonation processes are different because of different molecular weight distributions of their remained organic substances.
Therefore the classification of organic substances by their molecular weights and the measurement of THM formation potential of each classified component are important for the selection of treatment processes.
