Apparatus for separating dispersed phase contaminants from a continuous phase liquid, the dispersed phase contaminants including coarse contaminants, colloidal contaminants and ionized contaminants, comprises a generally cylindrical housing having a generally vertically extending longitudinal axis; a foraminous partition mounted within the housing at the middle thereof so as to be transverse to the longitudinal axis, the foraminous partition comprising substantially non-porous material shaped to define a plurality of longitudinally extending foramina, the foraminous partition co-operating with the longitudinally upper portion of the housing to define a sweep chamber and with the longitudinally lower portion of the housing to define a sludge sump; inlet means mounted in the housing for introducing contaminated liquid into the sweep chamber, the inlet means disposed so as to facilitate a laminar, whirling flow of liquid within the sweep chamber to generate forces for displacing the coarse contaminants generally outwardly and downwardly within the sweep chamber to separate the coarse contaminants from the continuous phase liquid; baffle means mounted in the sweep chamber, so as to extend into said whirling flow of liquid the baffle means defining impingement surfaces for the coarse contaminants and the colloidal contaminants to facilitate the separation and sedimentation thereof from the liquid and also defining a large attractor surface to facilitate the separating of the ionized contaminants from the continuous phase liquid by electrostatic bonding; the sludge sump for receiving said contaminants after separation; and outlet means mounted in the housing generally centrally of the sweep chamber for removing the continuous phase liquid after separation of the dispersed phase contaminants. The invention is described with reference to devices for continuously treating the lubricating oil in an internal combustion engine.
