It is well known that algae and their metabolites may form
disinfection by-product during chlorine disinfection process, but
the quantitative relationship between algae and disinfection by-
products formation potential (DBPFP) is rarely reported. In the
present study, the intracellular and the extracellular metabolites
from Microcystis aeruginosa in different growth phases were
harvested and separated into hydrophilic and hydrophobic groups,
and the variations of DBPFP in different groups were investigated.
The results show that although the cell density of M. aeruginosa
in decline phase was only one sixth of that in stable phase, the
total DBPFP in the two growth phases were comparable. This
implied that the average DBPFP in specific cell of decline phase
is much higher than that of stable phase. The increased DBPFP
in intracellular organic matter (IOM) of decline phase could be
attributed to the increase of hydrophilic organic in IOM while
the increased DBPFP in extracellular organic matter (EOM) is
mainly caused by the increase of hydrophobic organic in EOM.
The obtained results indicated that DBPFP could change with
the algal growth phases and the actual disinfection risk cannot
be simply evaluated by cell density in water, and the algal laden
water in autumn, the end of algal bloom season may even danger
to be disinfected than that in summer.
