Abstract
Procédé pour traiter des eaux résiduaires par une matière adsorbante régénérable telle que le charbon actif à une dimension de grain déterminée (nominale) dans un appareil d'adsorption avec récupération de la matière adsorbante sur un tamis et régénération de cette matière adsorbante, par exemple dans un four. Avant d'envoyer la matière adsorbante au four, on en sépare une fraction de grains de dimensions inférieures à la dimension de grain nominale mais supérieures à 10 % de la dimension de grain nominale et on remet cette fraction en grains à la dimension nominale avant de la recycler à l'appareil d'adsorption avec le reste de la matière qui, entre temps, a été régénérée. Le procédé selon l'invention permet d'éviter les fortes pertes constatées habituellement dans les régénérations au four à couche tourbillonnaire.
