Abstract

L'invention concerne un procédé de séchage thermique de boues. Ce procédé consiste à mettre les boues en contact avec un courant gazeux à faible teneur en humidité à température élevée, le courant gazeux ayant un débit et une vitesse tels que la boue est nébulisée en particules très ténues et déshydratée par évaporation de l'eau contenue. Application au traitement des boues d'épuration d'eaux usées.The invention relates to a method for thermal drying of sludge. This process involves contacting the sludge with a low moisture content gas stream at high temperature, the gas stream having a flow rate and velocity such that the sludge is nebulized into very fine particles and dehydrated by evaporation of the water contained. . Application to the treatment of sewage sludge.
