Sammanfattning

Drying is an energy-intensive unit operation and future sludge dryers should be able to take advantage of the secondary energy of industrial environments. This work reports the use of a pilot cyclone for drying biosludge at low temperatures and simulating the use of secondary waste heat. The pilot-scale experiments were performed according to an experimental design and the results interpreted using principal components and multiple linear regression. The dry solids content of processed sludge increased from 9 to 19-68% during the experiments with a predicted energy consumption of
