Abstract

An apparatus for filtering a machining liquid of an electroerosion machine includes a pump for supplying the machining liquid to a filter having a membrane. The filter is constructed in such a way that the concentrate is carried substantially tangentially to the membrane wall in a circuit, and the concentrate quantity per time unit carried substantially tangentially to the filter membrane wall in the circuit is greater than the permeate quantity per time unit removed from the filter.
