Abstract
A method and apparatus in which a water sludge suspension is initially separated from the water by skimming and then is conveyed to a dewatering station at which the sludge is oscillated or vibrated to separate mechanically the water from the solid sludge material. Preferably, at the dewatering station, the sludge is dropped a predetermined distance onto a sieve, the impact of the falling sludge producing a squeezing action on the sludge to initially exude the occluded water. The sieve, which is inclined, is then oscillated or vibrated to work the sludge to further exude water therefrom and to urge the sludge down the inclined surface of the sieve. After traveling to the bottom of the sieve, the sludge, now substantially dewatered, is received by a container for disposal.
