Abstract

a Secteur technique : traitement des résidus des bains usés basiques et des bains usés acides ayant servi au décapage et à l'anodisation de pièces en aluminium. b. Caractéristiques : on fait réagir le bain basique ayant une teneur de 60 g Al/l avec le bain acide ayant une teneur de 10 g Al/l dans la proportion en volume de 59 % du premier pour 41 % du second. Ladite proportion étant contrôlée par le pH du produit de réaction maintenu à 8,5. c. Applications : élimination des rejets polluants et obtention d'alumine à titre de sous-produits nobles.
