Abstract

Procédé de régénération d'un milieu filtrant colmaté par une couche de microorganismes, en particulier de microorganismes marins. Le procédé selon la présente invention permet la régénération d'un milieu filtrant dans lequel le milieu est traité avec un liquide décomposant les matériaux organiques déposés sur le milieu filtrant. Le liquide pour la génération du milieu filtrant est de préférence de l'acide sulfurique concentré. De plus, une unité filtre est prévue, qui comporte un moyen pour amener en contact le milieu filtrant avec l'acide sulfurique concentré. Application à la régénération des filtres.
