摘要： An apparatus (1) for recovering caustic soda from caustic solutions from a bath which is the result of the pickling/satinizing of substantially metallic articles, in which there is aluminum, by immersion in caustic soda arranged in a containment tank (2), comprising:
- means (3) for drawing the bath from the containment tank (2),
- at least one decantation tank (4) of the bath, for the at least partial separation of aluminum from the bath and for reducing the aluminum content of the bath, the decantation tank (4) being associated in input with the drawing means (3),
- means (6) for introducing a crystalline germ for activation of the precipitation of aluminum-based compounds, the introduction means (6) being associated with the decantation tank (4); and
- means for introducing water which are associated with the decantation tank (4).
