Abstract: The invention relates to a filter system for removing and/or neutralizing undissolved oils, greases and salts, preferably also floating bodies, such as metal debris, on/in water-containing emulsions from, in particular, containers and tanks that are used for holding and storing emulsions.

Abstract: A filter system for removing and/or neutralizing undissolved oils, greases, and salts on/in water-containing emulsions from, in particular, tanks and baths that are used to hold and store emulsions, which are used to cool and lubricate workpieces and tools during machining, comprising at least one emulsifier filter, a downstream suction/pressure pump, a unit for gas enrichment, an adhesion filter having an automatic deaerator, a downstream oil-collecting vessel, and a capillary filter, wherein these are combined as a unit, such that the oil/grease film and the emulsion can be mechanically, chemically, and biologically treated.
