Abstract

a. Procédé de transmission d'un liquide entre compartiments d'activation séparés destinés à la purification biologique de l'eau. b Procédé caractérisé en ce qu'un mouvement continu est communiqué au liquide active en utilisant, d'une part, l'aération pour le faire se déplacer vers le haut, et d'autre part, la pression exercée par cette aération pour le faire passer d'un compartiment à un autre. c. L'invention s'applique dans le domaine de la purification biologique de l'eau.at. A method of transmitting a liquid between separate activation compartments intended for the biological purification of water. b Method characterized in that a continuous movement is communicated to the active liquid by using, on the one hand, the aeration to make it move upwards, and on the other hand, the pressure exerted by this aeration to do so move from one compartment to another. vs. The invention applies to the field of biological purification of water.
