    摘要: The present invention concerns the treatment of an aqueous effluent and consists of ridding it of the iron which it contains, notably in the form of a complex.
    The method according to the invention consists of treating this effluent by successively a silicate, and a magnesium and aluminium hydroxycarbonate, then decanting and filtering.
    The method according to the invention is particularly useful in the treatment of photographic effluents.
