Treatment of O/W Emulsion is very important to develop 15ppm Bilge Separator for new IMO regulation It is too difficult to demulsify the emulsion in the bilge waste water, so we use chemical treatment to break emulsion stability. Broken oil particle is treated by flotation 15ppm Bilge Separator on the Ship doesn't have enough time to treat Bilge waste water because of limited space in the ship. For the solution to this problem, we experiment to find primary factors as coagulant, pH, amount of inputting coagulant, and type of flotation. On the basis of test results, we decided primary factors.

Treatment of Emulsion is very important to development of Bilge Separator for new IMO Regulation. It is too difficult to demulsify the emulsion in the bilge waste water, so we use chemical treatment to break emulsion stability. Broken oil particle is treated by flotation. Bilge Separator on the Ship doesn't have enough time to treat Bilge waste water because of small space in the ship. For the solution to this problem, we experiment to find primary factor as coagulator, pH, and amount of coagulator. As the basis of test, we decided coagulator, pH and quantity of coagulator.
