Abstract (en)
[origin: WO2010076287A2] The invention relates to a method for processing a nitrous aqueous liquid effluent containing nitrates of metals or metalloids, including the step of calcinating the effluent in order to convert the metal or metalloid nitrates into metal or metalloid oxides, at least one compound selected from the metal or metalloid nitrates and the other compounds of the effluent resulting in a sticky oxide upon calcination, and a dilution additive including at least one metal or metalloid nitrate resulting in a non-sticky oxide upon calcination being added to the effluent prior to the calcination step in order to provide a mixture of effluent and dilution additive.
