Abstract:
1. A cylindrical settler for use with a light phase material and a heavy phase material, having a longitudinal axis and a transverse plane generally perpendicular to the longitudinal axis, comprising: a generally conical base centered on the longitudinal axis and lying generally in a first transverse plane; a cylindrical outer wall centered on the longitudinal axis and connected to the outer edge of the base, wherein the outer wall stands generally vertically; a cylindrical mix tank, centered on the longitudinal axis and inside the outer wall, configured to mix the light phase with the heavy phase; a discharge weir configured to receive overflow of the light phase; an outlet configured to receive outflow of the heavy phase; and a generally conical first coalescence fence, centered on the longitudinal axis, extending outwards from a first location on the exterior surface of the mix tank, configured to promote separation of the light phase from the heavy phase in a mixture of the light phase and the heavy phase materials.
