ABSTRACT:
Sludge containing metal hydroxide is first subject to a separation treatment where solid particles are removed, and then dewatered to obtain a greater concentration of the metal hydroxide. The dewatered sludge attains a thixotropic character whereupon it is applied to a carrier in a film-like manner. The film is heated and then sintered so as to achieve a metal oxide that is harmless and easily handable. The separation and dewatering steps of the process are carried out in a first apparatus having a suction drum surrounded by a filtering cloth that removes the water contained in the sludge and transfers it to a second apparatus having a rotating carrier for receiving on the circumference thereof the metal hydroxide in a film form, whereupon the film is heated during rotation of the carrier and sent to a sintering apparatus for conversion to a metal oxide in a granular or powder form.
