A vessel and method for removing immiscible fluid from contaminated water, the vessel comprising: at least one chamber; an injection line in fluid communication with an inlet of the one chamber; bubble generation means in fluid communication with the injection line for injecting gas bubbles into the injection line and allowing mixing in the injection line of the gas bubbles and the contaminated water to form an inlet fluid; an inlet weir within the chamber adjacent the inlet; an immiscible fluid weir within the chamber; a trough for collecting the immiscible fluid and allowing the immiscible fluid to flow out of the at least one chamber through an immiscible fluid outlet; and a cleaned water outlet generally at the bottom of the chamber; wherein when the inlet fluid is injected into the chamber, it passes through the inlet and over the inlet weir, the cleaned water flows downwardly toward the cleaned water outlet, and a remaining mixture of the immiscible fluid and the gas bubbles floats through the chamber to pass over the immiscible fluid weir and down the trough to the immiscible fluid outlet.
