Abstract

Empirical equations for explaining trihalomethane (THM) distribution were established based on data on tap water in Osaka City before and after starting the advanced treatment and were represented by the following equations for bromodichloromethane (S1), dibromochloromethane (S2) and bromoform distribution factors (S3) as a function of chloroform distribution factor (S0), respectively: S1 = −0.97S 20  + 0.75S0 + 0.19 (regression coefficient: r = 0.71), S2 = 0.13S 20 −0.76S0 + 0.51 (r = 0.98) and S3 = 0.83S 20 −0.99S0 + 0.30 (r = 0.97). Further, the derived equations were verified by THMs data of Osaka Prefecture and its surrounding cities (except for Osaka City), receiving a combination of advanced treated water and conventionally treated different source water.
