Abstract
A system for dewatering a material comprising a first storage for holding a material, the first storage operably connected to a slitter, wherein the slitter receives the material, separates the material into a plurality of clumps, and deposits the plurality of clumps of material substantially evenly on a conveyor belt, wherein the conveyor belt is partially porous to allow water to pass through but preventing material from passing through the conveyor belt, and wherein the conveyor belt is operable to convey the material from the slitter to a compression zone; the compression zone comprises at least one high pressure press, the at least one high pressure press comprises at least one hydraulic actuator operably connected to at least one compression plate, the at least one compression plate having a top surface, a bottom surface, and plurality of side surfaces, wherein the at least one hydraulic actuator articulates the at least one compression plates to engage the material positioned on the conveyor belt; the bottom surface comprises a recess substantially proximate the plurality of side surfaces, wherein the recess receives a seal when the at least one compression plate actuates to engage the material on the conveyor belt so the seal forms a substantially water-impervious barrier between the at least one compression plate and the conveyor belt defining a cavity in which the material is compressed; at least one knife positioned proximate the at least one compression plate operable to remove material from the bottom surface of the at least one compression plate after a compression cycle; and at least one drain positioned under the conveyor belt to carry water removed from the material away from the conveyor belt.
