Zusammenfassung:	The liquor are worked up and transformed by being sprayed onto a compact moving layer of a solid contact material, which is brought into contact with a stream of hot oxidising gases, which evaporate the liquid constituents of the liquor and transform its iron salts into iron oxide. Pref., the contact material consists of an iron oxide such as mill scale and the moving bed is inclined and vibrated. The plant is intended for iron and steel pickling bath processing and solves the problem of disposal of the liquors without causing pollution.
