Abstract

Method and apparatus for separating residual quantities of liquid treatment agents from drum units with drums (13) having perforated walls, and the pourable mass parts (21) contained therein, after their electroplating and/or chemical surface treatments, the drum unit remaining protruding above the liquid level of treatment agent during the separating operation. The separating operation is carried out by means of short gas pulses from a line system (11) which are released inside the drum (13). The individual gas pulse released generates a pressure wave inside the drum which tears away the liquid residues adhering to the drum unit and its load. The liquid residues fall into the working container in the form of droplets together with the treatment agent. <IMAGE>
