摘要： A method and apparatus for dewatering sludges and/or concentrating suspen and dissolved impurities in solutions by simultaneously freezing and rotating same. Rotation of the sludge is accomplished in a rotatable cylindrical apparatus capable of controlled rotational rate sufficient to continuously maintain a thin layer of water between suspended particulate impurities and an ice front which forms on inner cylindrical surfaces of the cylindrical apparatus. The ice front moves progressively inwardly to displace the suspended impurities toward the center of the cylindrical apparatus, thereby concentrating the sludge both by this displacement and by the removal of liquid water from the sludge. The concentrated sludge is discharged from the cylindrical apparatus when the rotation of said apparatus becomes insufficient to maintain the thin water layer between the ice/sludge interface. The annular, cylindrical body of ice is removed by heating of external surfaces of the cylindrical apparatus to cause the ice to slide from said apparatus. The low temperatures required for ice formation can be derived from the natural cold temperatures of the winter months in appropriate locations.

摘要： An apparatus for dewatering aqueous sludge is disclosed. A porous drum is partially immersed in a sludge pond. A porous belt is connected between the drum and a roller which moves the belt. As the belt moves, the sludge adheres to the belt. A vacuum is drawn on the interior of the drum, removing some of the water. Sludge which is conveyed on the belt is frozen as it approaches the roller. The frozen sludge is broken into smaller cakes as it leaves the roller. The frozen cakes are subsequently dethawed providing a solid residue which is disposed.
