    The sludge could be heated to a temperature where the metal hydroxide would thermally convert to metal oxides. The oxides of metals tend to be much less water soluble than their hydroxides. The sludge would take on the form of a slag with a reduced volume and should present less of an environ- mental hazard after disposal.
