This study was conducted to evaluate the chlorinated disinfection by-products formation potential(DBPFP) produced from the cell and extracellular product(ECP) of Chlamydomonas pulsatilla after chlorination. Reaction yields of DBPs produced by C. pulsatilla of ECP and the cell were 0.007 μmol/mg·C and 0.808 μmol/mg·C respectively. Also, SUVA values of ECP and the cell were measured as 0.313 L/mg·m and 1.052 L/mg·m respectively. The DOC of cell was found to be lower than that of ECP, while the SUVA value and reaction yields for the cell were higher than those of ECP. For ECP, most of the DBPFP was composed of trihalomethanes (THM; 47.3%) and haloacetonitiles (HAN; 38.83%). THM and HAN were the major DBPFP produced by the cell. Chloroform was found to be the major THM compound; 98.3% for ECP and 99.98% for the cell. Dichloroacetic acid (DCAA) and dichloroacetonitrile (DCAN) were identified as the major haloacetic acid (HAA) ans HAN compounds formed by ECP and the cell as a precursor, respectively. As the chlorine dose was increased, concentrations of DOC, THMs, and HANs were increased. However, the chlorine dose decreased the concentration fo chlorophy Ⅱ-a.
