In this study, samples were taken from six conventional water treatment plants for disinfection by-products analysis. Results from the analysis revealed that trihalomethanes (THMs) concentrations in all samples were below regulatory levels (100 μg/L). Although the national standard for haloacetic acids (HAA5) has not yet been promulgated in Taiwan, samples from two water plants contained HAA5 concentrations exceeding the USEPA limit (MCL of HAA5 of Stage 1, 60 μg/L). THMs and HAA5 were found to be the major disinfection by-products in all water treatment plants. It was noted that the concentration of HAA5 in most samples was higher than that of the trihalomathanes. However, the formation potential of THM (THMFP) was found to be higher than that of HAA (HAAFP). Good correlation also was found between THMFP (or THMFP) and HAA5 (or THMs). In evaluating the performance of the treatment processes, it was found that conventional water treatment processes followed by activated carbon were effective in removing disinfection by-products (DBPs) from source water with pre-ozonation. The treatment processes were at their optimum performance in removing contaminants when O3/TOC0 was held at 0.75.
