Abstract

An apparatus comprising a housing - in which at least one compartment is formed - that can be connected to the suction side of a pump, which compartment is open on the underside and accommodates a rotor which is equipped with a member of downwardly projecting knives (10) which have different angular positions and which are arranged in groups that are approximately equidistant from the rotary shaft (5).
