Oil and Grease content of Bilge Water obtained from Ships Docked at the Warri Seaport, Delta State, Nigeria

Abstract

This study is aimed at empirically investigating the impact of oil and grease content of bilge water on Nigeria’s Coastal environment. Literatures were reviewed and the study adopted an experimental research design. The researchers applied laboratory experimental analysis, physicochemical parameters of ship generated wastewater from vessels against the DPR standard was measured. The results of the analysis showed that the value of oil/Grease content of Bilge water is 72µg/L while the DPR limit value is 48 µg/L, however, the mean value of Oil/grease content of wastewater is 35.0 µg/L.  Based on the findings, the researchers rejected hypothesis one and accepted hypothesis two, hence concluded that the value of oil/grease content of bilge water is significantly different from the mean DPR Limit. They also concluded that the mean value of oil/grease content of wastewater is not significantly different from the mean DPR Limit. Based on the result, the researchers recommended appropriate measures for the disposal of ship wastewater; better policy implementation and enforcement for strict compliance on bilge water disposal as well as adequate treatment of onboard wastewater.
