METHOD AND APPARATUS FOR DRYING SEWAGE SLUDGE

Method and apparatus for drying sewage sludge. The liquid sewage sludge is given a pasty consistency in a previous drying arrangement (10), and said pasty sewage sludge is shaped into particles having a relatively important surface in a shaping arrangement (16). Said particles are then exposed to a...

Zusammenfassung:	Method and apparatus for drying sewage sludge. The liquid sewage sludge is given a pasty consistency in a previous drying arrangement (10), and said pasty sewage sludge is shaped into particles having a relatively important surface in a shaping arrangement (16). Said particles are then exposed to a drying gas-stream (52) in a drying arrangement (48). Procédé et appareil correspondant de séchage de boues de curage. On donne aux boues liquides de curage une consistance pâteuse dans un agencement de séchage préalable (10), et on façonne avec ces boues pâteuses de curage des particules ayant une surface relativement importante dans un agencement de façonnage (16). Ces particules sont ensuite exposées à un courant de gaz de séchage (52) dans un agencement de séchage (48).
