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.

A solids separator for use in a composting system for separating solid waste from liquid waste in a stream of waste includes a housing defining a waste inlet for receiving the stream of waste, a liquids outlet for passing the liquid waste, and a solids outlet for passing the solid waste. A separator belt is positioned within the housing and extending between the liquids outlet and the solids outlet, the separator belt defining a plurality of apertures through which the liquid waste passes through the separator belt and into the liquids outlet. A drive cylinder is rotatably mounted within the housing for selectively rotating the separator belt such that a top surface of the belt is moved toward the solids outlet along with the solid waste that is extracted from the stream of waste.

A pulp-filter arrangement (1) comprises a rotatable drum (10) and a non-rotating valve arrangement (30). The rotatable drum (10) has a cylindrical water-permeable pulp-supporting shell (14), a plurality of drain pipes (16) and a rotating hollow shaft (18). The plurality of drainpipes (16) connects the rotating hollow shaft (18) with a collecting channel (22) situated radially directly inside the cylindrical water-permeable pulp-supporting shell (14). The non-rotating valve arrangement (30) is disposed within the rotating hollow shaft (18) for sealing off the rotating hollow shaft (18) from a radially inner outlet (24) of the drain pipes (16) when respective radially inner outlet (24) is situated within a sealed zone. The non-rotating valve arrangement (30) is further arranged to, in a transition zone immediately following the sealed zone, open a throttled passage between the rotating hollow shaft (18) and the radially inner outlet (24).

A method for continuously filtering a liquid slurry, such as an oil sand and solvent slurry, in a horizontal pan filtering device is provided. In particular, separate filtrate receivers are built under the wet and the dry sectors of a pan filter to take advantage of the liquid seal at the wet sectors so that the solids in the slurry can be compressed by having a higher vacuum under the wet sectors.

According to various aspects and embodiments, a system and method for two-stage filtration is provided. The system includes an inlet fluidly connectable with wastewater, a first stage filter assembly that is fluidly connectable with the inlet and has a rotary drum with a filter surface configured for radially inward fluid flow, a second stage filter assembly that is fluidly connectable with the first stage filter and has a plurality of filter discs configured for radially outward fluid flow, and an outlet fluidly connectable with filtrate generated by the second stage disc filter assembly.

A microplastic filter includes a housing including an inlet configured to receive water. The microplastic filter also includes a fine filter disposed to rotate within the housing and configured to filter residues from the water. The microplastic filter further includes an inside wiper disposed within the fine filter. The inside wiper includes a center post disposed along a rotational axis of the fine filter and a helical curved wall spirally extending between the center post and the fine filter, where the helical curved wall is configured to guide a portion of the water to backflow through the fine filter and force away at least some filtered residues from pores of the fine filter to prevent fouling or clogging of the fine filter. In addition, the microplastic filter includes an outside wiper spirally disposed around the fine filter and configured to dislodge other filtered residues from the fine filter as the fine filter rotates.

A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

In a water treatment system, which may be a wastewater treatment plant, a single-inlet drum screen is installed with its rotation axis perpendicular to the pattern of flow in a channel. Retrofitting of an existing screening system with a different form of screen, residing in an existing concrete channel is described.

A screen assembly (10) for a horizontal screen machine has a screen body (12) diverging axially from an inlet end (13). A base wall portion (15) mounts the screen body (12) for rotation and includes eight substantially radial webs (16). An annular wall portion (21) is located adjacent the inner end (13) and includes drain passages (24) adapted to drain discontinuities in a bonding layer comprising a moisture cure polyurethane sealant/adhesive overlying the annular wall portion (21). Wear resistant tungsten carbide elements (26) include a plurality of apertures (27) extending through a wear face to a bonding face. Voids (32) in the discontinuous bonding layer (31) provide fluid interconnection between the apertures (27) and the drain passages (24). A replaceable screen member (33) is releasably secured at an inner ring frame (22) and an outer ring frame (36) of the screen body (12).
