Abstract: An inline thickener including a cylinder, a wiper inside the cylinder and rotating relative thereto for cleaning an interior surface of the cylinder, an outer housing, a sludge inlet for inserting sludge under pressure into a first end of the cylinder, a sludge outlet at a second end of the cylinder, and a filtrate outlet for allowing a portion of liquid removed from the sludge to exit the inline thickener. The pressure of the sludge inlet, the sludge outlet and the filtrate outlet are measured and controlled to allow for a selected percentage of the liquid in the sludge entering the inline thickener to be removed from the sludge. The sludge is not mechanically compacted within the inline thickener.

Abstract: A liquid extraction assembly for extracting liquid from a mass including a housing having an inlet, an outlet, and a path between the inlet and the outlet. The housing has the mass forced into the inlet to move the mass from the inlet to the outlet. The housing includes a rotating screen adjacent the path, with the rotating screen defining one wall of the path. The rotating screen includes a plurality of openings located at the path. Pressure from mass forced into the inlet presses the mass against the openings of the rotating screen to thereby force at least a portion of liquid in the mass to pass through the openings of the rotating screen. The housing has at least one stirring arm extending into the path between the inlet and the outlet, the at least one stirring arm stirring the mass in the path.

Abstract: A liquid extraction assembly for extracting liquid from a mass comprising a housing having an inlet and an outlet and a path therebetween. The housing includes a rotating screen adjacent the path. The housing can have a nozzle at the inlet. The housing can include an inflatable member providing a seal adjacent the screen for maintaining the mass in the path. The housing can include a center seal rotating with the screen and a fixed scraper in the path and adjacent the at least one rotating screen, with the center seal including a notch for accepting a tip of the scraper therein. The housing can also include side walls and an annular seal located between the side walls, with the annular seal defining an outer periphery of the path and having a rotating top end portion allowing an area of the outlet to change.

Abstract: An assembly for extracting liquid from or adding liquid to a mass comprising a housing having an inlet, an outlet and a path therebetween. The housing is configured to have the mass forced into the inlet to move the mass from the inlet to the outlet. The housing includes at least one rotating screen adjacent the path, with each at least one rotating screen defining one wall of the path. The at least one rotating screen includes a plurality of openings located at the path. Pressure from mass forced into the input forces the mass along the path between the inlet and the outlet. The housing includes at least one rotatable scraper in the path and adjacent the at least one rotating screen, the at least one rotatable scraper cleaning the at least one rotating screen as the rotating screen is rotated past the at least one rotatable scraper.

Abstract: A device for adjusting the lateral position of an endless belt comprises a sensor for detecting the lateral position of the endless belt relative to a predetermined position, a roller disposed adjacent to the endless belt, and a controller operatively connected to the sensor and to the roller by way of an air bellows, wherein the controller will automatically cause the air bellows to move the roller to urge the endless belt toward the predetermined positioned when the sensor detects that the lateral position of the endless belt is away from the predetermined position.

Abstract: A belt filter press for deliquifying a material comprises two endless filter belts disposed adjacent each other so that a portion of the belts travel together and converge towards one another in a curved wedge section through which a material is progressively compressed, wherein the concavity of the wedge section is oriented toward gravity.

Abstract: A belt filter press for deliquifying a material comprises two endless filter belts disposed adjacent each other so that a portion of the belts travel together and converge towards one another and between which a material is progressively compressed, and a substantially cylindrically-shaped primary roller around which the belts are compressed having a longitudinal axis and ends, wherein the primary roller is provided with a plurality of radially extending fins, each of which has a wing at the free end thereof.

Abstract: A belt filter press for deliquifying a material comprises two endless filter belts disposed adjacent each other so that a portion of the belts travel together and converge towards one another and between which a material is progressively compressed, and a belt washer for cleaning the belt of residual material, wherein the belt washer has at least one wiper holder and at least one belt wiper, wherein the at least one belt wiper is disposed against a first surface of one of the belts and removably retained thereagainst by the at least one wiper holder.
