Abstract:
1. A water treatment vessel for removing immiscible fluid from contaminated water to produce cleaned water, the vessel comprising: at least one chamber; an injection line in fluid communication with an inlet of the at least one chamber, the injection line for containing and transmitting the contaminated water from a source to an inlet weir located within said 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; said inlet weir supported within the at least one chamber by first mounting means, said first mounting means being a direct mounting of the inlet weir on a first interior surface of the at least one chamber, said inlet weir in a first of said at least one chambers being in fluid communication with said inlet and thus in fluid communication with said injection line and said inlet fluid; an immiscible fluid weir spaced from the inlet weir, supported within the at least one chamber by second mounting means, said second mounting means being a direct mounting of the immiscible fluid weir on a second interior surface of the at least one 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 at least one chamber; wherein when fluid is received in said inlet weir of the at least one chamber, it passes 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.
