Abstract:
1. A separating device for separating a first liquid from a second liquid, wherein the first liquid has a lower specific density than the second liquid, comprising: a receptacle with an inside wall; an inlet and an outlet, wherein the inlet is arranged above the outlet; and a separating member made of a permeable filter material that is capable of adsorbing the first liquid and is arranged within the receptacle between the inlet and the outlet and is configured in such a manner that it floats on the second liquid when it is clean, and sinks with increasing adsorption of the first liquid, wherein the separating member has a smaller diameter than the receptacle so that there is a lateral distance between the inside wall and the floating separating member, and a liquid mixture consisting of the first liquid and the second liquid is filled into the receptacle through the inlet in such a manner that it must flow through the separating member completely so that the separating member can adsorb the first liquid; and wherein the separating member has an internal cavity and an inlet opening that is oriented towards the inlet, the internal cavity being surrounded by said filter material except for the inlet opening and that the liquid mixture is filled into the internal cavity.
