Method and apparatuses for screening

Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

Stormwater treatment device

A stormwater treatment device includes a tank defining an internal volume and having an inlet and an outlet, a rotatable screen unit mounted within the tank, the rotatable screen unit being barrel-shaped to define a through path with an inlet end and an outlet end. The rotatable screen unit includes a screen structure with a plurality of screening openings for allowing passage of at least some water from the through path outwardly through the screen structure while inhibiting passage of trash items through the screen structure such that trash items move along the through path from the inlet end to the outlet end. The rotatable screen unit includes a plurality of external drive paddles that rotate with the screen structure and that interact with water that has been screened by passing outwardly through the screen structure interacts with the external drive paddles to cause rotation of the rotatable screen unit.

Device and method for detecting wear of a separating element

The present invention relates to a rotary pressure filter comprising a filter drum, a housing, and at least one separating element which divides a process chamber in a gas-tight manner into a plurality of process portions. A sensor is arranged on the side of at least one separating element that faces the housing. The sensor comprises a coil and a rod which is arranged inside the coil. The rod is designed to be displaced in the coil on the basis of a change in the distance of the separating element from the sensor. The invention further relates to a method for detecting wear of a separating element of a rotary pressure filter.

ROTARY PRESSURE FILTER

A rotary pressure filter suitable for use in treatment of one or more of medical products or foodstuffs, the rotary pressure filter. The rotary pressure filter comprises a filter drum that can be rotated about an axis of rotation. The rotary pressure filter comprises a plurality of filter cells arranged along an outer circumference of the filter drum, with a housing surrounding the filter drum. A process space is formed between the filter drum and the housing. The rotary pressure filter comprises at least one separating element dividing the process space into a plurality of treatment zones. At least one treatment zone is associated with a housing connector via which one or more of fluid or suspension can be introduced into the respective treatment zone.

Rotary drum screen method for thin stillage filtration

A rotating drum screen method for separating solids from thin stillage obtained from ethanol fermentation, the thin stillage comprising one or more of solids and suspended solids. Thin stillage is chemically treated with an anionic polymer to form stable particles of one or more of solids and suspended solids. Introducing the treated thin stillage into a rotating drum screen system. The drum screen includes a filter screen that retains at least a portion of the solids within a hollow portion of the drum screen and which produces a liquid effluent that is discharged from an outer surface of the drum screen. The retained solids are removable from the drum screen via a solid discharge end. A head box is disposed within the hollow portion of the drum screen and has a plurality of fluid flow channel dividers dividing and directing an influent stream outwardly against the drum screen.
