The invention is directed to a method for the separation of liquid substances from one another with a mechanical collection unit. A collection unit (1) having an essentially smooth surface is held partly submerged in the substance mixture (4-5). The surface (3) of the collection unit at the liquid layer (5) to be collected is made to move deeper (h) relative to the surface (6) of the base liquid (4) into said base liquid such, that the substance layer (5, 7) remains essentially integral. The surface (3) of the collecting unit presses the substance (5, 7) to be collected downward into the base liquid (4), at which buoyancy affects the substance layer such, that the substance (5, 7) attaches onto the surface (3) of the collecting unit, from which it is removed above the liquid surface (6). The invention is also directed to an apparatus which uses the said method. The apparatus comprises a collection unit to be submerged into the base liquid (4), said unit comprising an essentially smooth adhesion surface (3) for continuously pressing into the liquid mixture (4-5) for holding the substance layer and for pressing it into the base liquid (4). The apparatus further comprises means (8) for the continuously operating removal of the attached substance (7) from the adhesion surface (3) above the liquid surface (6). |
