Abstract
Process for the treatment of decontamination effluents, more particularly the components of nuclear reactors, of the type containing in solution permanganate, phosphate and sulphate ions and active manganese, chrome and cobalt ions, wherein it comprises the successive stages of reducing the permanganate ions by adding hydrogen peroxide, alkalization to a pH equal to or above 12, separation of the precipitate formed and final acidification of the residual liquid phase to bring its pH to a value compatible with discharge into the environment. The invention also relates to an apparatus for performing the above process.
