Abstract: Disclosed is an apparatus for the gravitational separation of the first and second liquid phases of a two phase liquid containing predominantly a continuous first liquid phase with a dispersed second liquid phase having a lower specific gravity than the first liquid. The apparatus comprises a tank defining an interior chamber. A feed inlet introduces the two 5 phase liquid into the lower portion of the chamber. The upper portion of the chamber has an upward flow zone through which the two phase liquid rises, with the dispersed second liquid rising more than the first liquid and being separated therefrom due to the second liquid's lower specific gravity. The second liquid forms a floating layer and a conduit directs separated second liquid from the floating layer to a second liquid outlet.

Abstract: The water treatment system can have a tank having an elongated shape with two opposite ends and two transversally opposite sides; a flocculation chamber at one of the opposite ends of the tank, the flocculation chamber having at least one treated water inlet and a mixer and a separation chamber adjacent to the flocculation chamber inside the tank, the separation chamber having at least one treated water outlet. A flow straightener system can be provided having a transversally-oriented wall forming an overflow baffle and extending upwardly between the flocculation chamber and the separation chamber, the transversally-oriented wall having an upper edge and a plurality of vanes being vertically and longitudinally oriented, parallel to one another and transversally interspaced from one another along the upper edge of the wall, the vanes extending in at least one of the two transversally opposite sides of the tank.
