Abstract: The invention refers to an equipment for surface treatment of continuously running strip particularly pickling equipment wherein the strip runs longitudinally through a horizontally arranged container receiving treatment liquid while being closed by means of a lid. For optimizing such equipment particularly for improving the quality of treatment and for minimizing the period of time needed for treatment it is suggested to provide within the container a separate treatment channel (4) which is closed through an intermediate cover (6) and receives treatment medium through nozzle bars (9) and (10).
