Apparatus for separation by decantation

摘要

A decantation separation apparatus in which the material to be separated flows upwardly through an annular weir, and overflows to a decantation zone defined between the weir and a surrounding jacket. The separated liquid is withdrawn from the bottom of the decantation zone and the separated lighter phase from the top of the jacket, an obstacle for example in the form of a thin plate, being provided in the decantation zone above the liquid outlet for slowing the velocity of liquid within the decantation zone.
