ABSTRACT |
The objective of this study was to assess the variation in the concentration of assimilable organic carbon (AOC) in a drinking water
resource, and investigate the characteristics of AOC derived from algae. The seasonal change in AOC at the Kamafusa dam corresponded
to changes in the algal cell number. In order to understand the relationship between AOC and algae in a water resource and water
purification plant, two kinds of laboratory experiment were performed. The algal culture experiment showed that extracellular organic
matter (EOM) that was released during the growth of Phormidium tenue with M-11 medium led to significant increases in the AOC
concentration, but no significant variation in the AOC concentration was observed with CT medium containing a high dissolved organic
carbon concentration. The chlorination experiment showed that the AOC included in EOM was not easily removed by chlorination,
although the AOC included in intercellular organic matter released from the algal cells by chlorination was removed under conditions
where residual chlorine was detected. |
