ABSTRACT:
A high efficiency hydrocyclone for separating liquid constituents of a mixture wherein one constituent is a dispersed phase in another continuous phase constituent. The separation chamber of the hydrocyclone is configured such that a first steep tapered or curved portion progresses to a second less steeply tapered or curved portion with the beginning of such second less tapered portion being arranged close to the inlet end. A third substantially cylindrical portion extends from the second portion to an underflow outlet and is of an extended length to provide for continued separation of the mixture and particularly to separate smaller droplet sizes of the dispersed phase.
