| Abstract: | The decolourization and Chemical Oxygen Demand
(COD) removal of azo dye solution in different
ozonation time and biodegradation processes were
evaluated to apply for reactive azo dye. Reactive Red
120 (RR120), Remazol Brilliant Blue R (RBBR),
Reactive Green 19 (RG19) and Reactive Black 5 (RB5)
have been selected amongst reactive azo dyes in
performing ozonation process. Ozonation is effective
for decolourization of reactive azo dye even with lower
ozone dose. Ozonation time of 5 minutes, 10 minutes
and 20 minutes are done to evaluate the performance
of ozonation and biological treatment. Contrarily,
significant decreased in COD concentration was only
observed within higher range of ozone doses. Higher
COD removal at high ozone dose was due to complete
oxidation of azo dye. COD removals are increases as
the increase of ozonation time and ozone dose.
Biodegradation processes will decrease the COD
value compare after the ozonation process. The
performance of ozonation process in removal of color
is 100% after 20 minutes ozonation. |
