Abstract

a. Appareil pour l'électroflottation. b Sur le fond 1 d'une cuve 2 courent sept barres 3 en graphite reliées entre elles et au pôle positif 4 d'un redresseur de courant par un circuit 5 électrique. Les barres 3 sont recouvertes d'un lit 6 de boulets de charbon qui s'étend sur tout le fond 1 de la cuve. Au-dessus de la face supérieure du lit 6 et parallèlement à celle-ci et aux barres 3 est monté un grillage 7 en acier inoxydable servant de cathode. c. Electroflottation.
