Uncontrolled discharged of bilge water from sea vessels is one of the
major pollutants for marine ecosystem due to its high amount
petroleum and oil content. In this research, organic material removal
from bilge water by using coagulation – flocculation and Fenton
oxidation was investigated. In coagulation-flocculation experiments,
the effects of different coagulants and their dosages on COD removal
were examined. Ferrous sulphate presented the best performance to
remove organic material. The maximum COD removal efficiency was
achieved as 40.7 ± 0.7%, and the optimum coagulant dosage was
determined as 250 mg L-1
. Regarding Fenton oxidation, different Fe2+
and H2O2 concentrations as well as different Fe2+/H2O2 ratios were
tested to identify optimum operational conditions. COD removal
efficiency of 59.0 ± 0.2% was achieved at 6 mM Fe2+ ions. The highest
COD removal efficiencies were obtained at 30 mM H2O2 and Fe2+/H2O2:
1/5. Despite the fact that Fenton oxidation presented a better
performance for organic material removal than coagulationflocculation, COD concentration in the effluent could not meet the
discharge limits. Therefore, Fenton oxidation under optimum
operational conditions was considered as an effective pre-treatment
method to remove organic materials from bilge water.
