Apparatus for treatment of waste water sludge

摘要

A method and apparatus for fragmenting waste water sludge particles to destroy sludge particles and to enhance a dewatering process performed on the sludge. Sludge is passed through a slotted rotor that centrifugally propels the sludge through slots in a surrounding annular stator. Sludge particles forcibly impact against the side surfaces of the stator slots to fragment into smaller sized particles. During the fragmentation process water located in the pores of the sludge particles is released. The free water can later be separated from the sludge in a dewatering apparatus. When passing through the rotor and stator slots, organic cells are broken apart and a portion of each is converted to dissolved sugars and proteins.
