Abstract
A weir assembly for use with a mixer-settler for liquid-liquid extraction includes in one embodiment an organic weir having an inlet opening below the free surface of the organic phase liquid and a vertically-adjustable front wall allowing adjustments in the position and/or height of the inlet opening. The organic weir can also feature an angled bottom coupled to a lip segment, an incline plate in the interior of the weir, and a front wall that is angled with respect to incoming fluid flow. In another embodiment the weir assembly can independently or additionally include an aqueous weir with a labyrinth section. The aqueous weir can optionally include an adjustable lip hingedly coupled to the top of the final partition in the labyrinth section.

An apparatus for liquid-liquid extraction configured to accommodate at least a first liquid phase and a second liquid phase, comprising:
- a settler compartment having a top, a bottom and a back wall;
- a first weir located in said settler compartment, said first weir comprising:
- a first side wall with an inlet opening that extends a first length at least partially between said top and bottom of said settler compartment;
- a second side wall that extends a second length at least partially between said top and bottom of said settler compartment, wherein said second length is greater than said first length;
- a third wall that extends between said first side wall and said second side wall, wherein said third wall extends non-parallel to said bottom;
- and
- a second weir located in said settler compartment adjacent said first weir, wherein said second weir includes a labyrinth section having an inlet opening and at least a first and second partition extending from said settler compartment bottom and at least a third partition extending from said settler compartment top and located between said first and second partition.
An apparatus for liquid-liquid extraction configured to accommodate at least a first liquid phase and a second liquid phase, comprising:
- a settler compartment having a top, a bottom, a back wall and opposing settler side walls that extend between said top an bottom;
- a first weir located in said settler compartment, said first weir comprising:
- a first side wall with an inlet opening that extends a first length at least partially between said top and bottom of said settler compartment, wherein said first side wall is oriented at a non-perpendicular angle to the opposing settler side walls;
- a second side wall that extends a second length at least partially between said top and bottom of said settler compartment, wherein said second length is greater than said first length;
- a third wall that extends between said first side wall and said second side wall;
- and
- a second weir located in said settler compartment adjacent said first weir, wherein said second weir includes a labyrinth section having an inlet opening and at least a first and second partition extending from said settler compartment bottom and at least a third partition extending from said settler compartment top and located between said first and second partition.

- a second side wall that extends a second length at least partially between said top and bottom of said settler compartment, wherein said second length is greater than said first length;
- a third wall that extends between said first side wall and said second side wall,
- wherein said third wall extends non-parallel to said bottom of said settler compartment, wherein the first weir inlet opening has a height and a location within said front wall of said first weir, and at least a portion of said front wall of said first weir is vertically adjustable such that the height or location of said inlet opening can be adjusted;
- and
- a second weir located in said settler compartment adjacent said first weir, wherein said second weir includes a labyrinth section having an inlet opening and at least a first and second partition extending from said settler compartment bottom and at least a third partition extending from said settler compartment top and located between said first and second partition.
