Oil spills at sea are a major problem to the environment as they severely damage the surrounding
ecosystems. Since crude oil is lighter than water, it floats on the sea surface. The initial treatment
of an oil spill at sea includes mechanically skimming the waterʹs surface, a mixture of floating oil,
emulsified oil, tar balls, etc. will be taken onto the recovery barge and delivered for treatment and
reclamation. A lab scale experimental research was conducted to investigate the effectiveness of
different oily-water treatment technologies. This research investigated the effectiveness of
Gravity Oil/Water Separation, Coagulation/Flocculation/Sedimentation, and Sand Filtration
technologies. Effect of different parameters such as hydraulic residence time, type of coagulant,
and coagulant dose were studied. It was concluded that more than 95% of oily compounds can be
separated from oily-water waste which is an excellent step in preventing sea-water pollution.
