Abstract

Procédé de traitement d’eau en vue d’en abattre la teneur en pollution organique dissoute et en micropolluants comprenant la mise en contact de l’eau avec du charbon actif dans un unique contacteur, l’extraction d’eau traitée du contacteur, l’extraction, la déshumidification, le séchage du charbon actif usagé et la désorption par micro-ondes de la pollution adsorbée sur le charbon actif sans stopper la mise en contact de l’eau avec le charbon actif et le recyclage de charbon actif ainsi régénéré dans le contacteur, l’ensemble du procédé étant mis en œuvre dans une même installation, caractérisé en ce que : le charbon actif est du charbon actif en micro-grains auto-drainants présentant un indice d’iode compris entre 900 et 1000 mg/g, une granulométrie comprise entre 300 μm et 1000 μm, une granulométrie moyenne (D50) comprise entre 500 μm et 600 μm et une proportion strictement inférieure à 5% en poids de grains présentant une taille inférieure à 400 μm ; l’extraction, la déshumidification, le séchage, la désorption et le recyclage du charbon actif en micro-grains sont mises en œuvre sans matériel provoquant le brassage important du charbon actif, la déshumidification comprenant un simple égouttage du charbon actif; le séchage est effectué par micro-ondes, le séchage et la désorption étant menés dans un même équipement micro-ondes fonctionnant selon un cycle de séchage afin d’obtenir un charbon actif séché présentant un taux résiduel d’humidité inférieur à 5 % en poids suivi d’un cycle de désorption ; le séchage par micro-ondes et la désorption par micro-ondes sont mises en œuvre sous atmosphère contrôlée ; et en ce qu’il comprend la destruction des composés organiques volatils émis lors de la désorption par micro-ondes.
