Secondary sludge produced in the papermaking process is dewatered by adding a material capable of absorbing water together with dry fibers to the secondary sludge, and mixing the secondary sludge with the dried fibers to produce a modified secondary sludge which has sufficient structure and low enough moisture that it may be further dewatered by mechanical means. The preferred fiber adding materials are those readily produced in the papermaking process, particularly dry primary sludge, dried fines and bark and fly ash from boilers.

The invention relates to a split seal device for use between a stationary body and a rotary body. The device utilizes a fractured seal ring which is fractured along two diametrically opposite uneven fracture lines to prevent leakage of fluid. A vulcanized rubber insert which circumferentially engages the outer surface of the split ring is cut along about at least one split line and is fitted within a rotary housing, the latter being designed for mounting on a rotating shaft. The fractured split ring has a contact face for frictional contact with a corresponding contact face of a seal ring of the stationary body. The seal ring is likewise fractured along two diametrically opposite uneven fracture lines and is retained adjacent innermost end of the stationary body. To decrease shock of rotation, the lugs which engage the rotary face to the rotary housing, are made flexible and resilient. The split seal device is mounted for engagement with the flexible lugs in general co-axial alignment with the rotating body.

A mechanical seal particularly well suited to use in rotary equipment handling abrasive slurries. The seal comprises a split rotary face biased toward a split stationary face by a cone spring. The cone spring is encased in elastomeric material which includes molded lugs which serve to transfer rotary motion from a drive sleeve to the rotary housing which contains the split rotary face. The seal forms a unitary cartridge which may be pre-set through the use of setting plates which establish a predetermined amount of compression of the cone spring.
