METHOD AND APPARATUS FOR DRYING SEWAGE SLUDGE

摘要

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).
