Abstract
The invention relates to a method and installation for treatment of an aqueous phase containing a used adsorbent powdery material, such as activated carbon powder, from a water purification or potabilization installation, wherein said method includes: a first step of desorbing the main part of the organic matter adsorbed on the used adsorbent powdery material consisting of placing said aqueous phase containing the used adsorbent powdery material in contact with a desorbent compound resulting in a first aqueous phase containing at least partially regenerated adsorbent powdery material and desorbed organic matter; a first step of separating by sedimentation the main part of the desorbed organic matter from the rest of the first aqueous phase containing the at least partially regenerated adsorbent powdery material leading to the production of a second aqueous phase containing the at least partially regenerated adsorbent powdery material; a first step of neutralizing said second aqueous phase containing the at least partially regenerated adsorbent powdery material; a second step of separating the at least partially regenerated adsorbent powdery material from said second aqueous phase leading to the production of a third aqueous phase containing the at least partially regenerated adsorbent powdery material.
