A screw press includes a press chamber in which a screw shaft is mounted such that the screw shaft is surrounded by a screen jacket and is rotatable about a screw shaft axis. The screen jacket is fastened to a screen jacket holding device including at least one beam running through the press chamber. The screen jacket is formed of a plurality of multipart screen baskets configured to receive a plurality of screen basket inserts, each multipart screen basket of the plurality of multipart screen baskets includes a semi-cylindrical first screen basket half shell and a semi-cylindrical second screen basket half shell. At least one pivot hinge is disposed between the first screen basket half shell and the second screen basket half shell. A basket lug is disposed on the first screen basket half shell and the second screen basket half shell.

The present invention discloses low cost, on-site, efficient, and compact (stationary or mobile) system for continuous (non-batch operation) conversion of waste to usable products such as sources of energy, fertilizer, etc.

A device according to various embodiments for preparing wet grain can include at least a first screw configured to receive wet grain. A second screw receives the wet grain from the first screw. At least one of a compressing element and a dehydrating element is included with at least one of the first screw and the second screw to cause a physical property change to the wet grain.

An effluent collector includes a filtrate receiving portion having a filtrate opening, and a pressate receiving portion having a pressate opening. The effluent collector includes a diverter barrier adjustably positioned above the pressate receiving portion. The diverter barrier is configured to adjustably direct at least a portion of a flow path toward or away from the pressate receiving portion.

Disclosed is a piston press of the type used in the field of the dehydration of products to be dehydrated such as sludge from a purification plant. More particularly, it relates to a piston press including a pressing chamber supplied with sludge and able to manage air streams that it generates, and to a method for using such a press. In a preferred mode of embodiment, the piston press includes a pipeline having a water removal branch and arranged so as to remove water extracted during a sludge-pressing operation, and an air circulation branch that can channel the volumes of air circulating in the press during the operation thereof, so as to direct the vitiated air, i.e. air that has been brought into contact with the sludge during the implementation of the press, towards a deodorization system.
