Disclosed is a dynamic separation and filtration system for dewatering and dehydrating of slurries and sludges. The system includes a compression filter press cylinder in which hydraulic pressure within a sealed liner is used to press and separate moisture from a sludge. A self-contained closed sealed liner pressurizing component is connected thereto, for supplying pressurized hydraulic fluid to the sealed liner, and a compressed air and vacuum and backflushing cylinder component is connected thereto for voiding the press cylinder of a resulting cake. A sludge transfer and metering component supplies metered quantities of sludge to the press cylinder. A dynamic filtration clarifier and thickener initially separates solids from a slurry and thickens the slurry into sludge that is supplied to the metering component.

A surgical collection assembly for filtering material from liquid obtained during surgery. A jar having an inlet and an outlet each adapted for connection to a suction line. A set of orientation features to position an upper portion of a collection basket within the jar such that an upper portion of the collection basket does not impede a flow of material entering the jar through the inlet. A bottom surface with a pattern of recessed paths in the bottom surface, the pattern of recessed paths connected to the outlet. A plunger assembly that may be reversibly attached to the jar so that a distal end of a plunger may be used to compress collected material within the collection basket to help remove fluid from the collected material. For certain uses, the surgical collection assembly may have a simple jar lid without an integrated plunger.

A device for separating and lifting solids from waste water has a stationary drum provided with a first filter screen and a screw conveyor. An auger shaft has a lower portion located inside the stationary drum, which is partially surrounded by a second filter screen. The lower portion is connected to a cleaning apparatus of the first filter screen formed by a plurality of comb-holder arms mounted on a cross shaped element. The comb-holder arms are integral at the opposite end to an anti-skid ring sliding in a sliding seat integral with the support frame. Each comb-holder arm has an elongated comb facing the first filter screen and in contact with the first filter screen. The comb-holder arms are connected to the auger shaft by an epicyclic secondary gear.

A method of operating a filter press, wherein filter material is fed into a filter chamber so as to form a filter cake between at least two sides of a flexible said filter medium. Filtrate is received from the filter chamber and the filter cake formed the filter chamber is discharged. Prior to discharging the filter cake, compression is applied on the filter cake formed within the filter chamber by providing compression fluid gas at a compression pressure exceeding a prevailing pressure within the filter chamber, directly on a side of the filter medium exterior to the filter chamber, so as to exert said compression pressure directly on said side of the filter medium, thereby causing the filter medium to yield against the filter cake.

A dewatering system for removing solids from an influent includes a filtration assembly and a feed pipe upstream thereof. The dewatering system includes a solids receptacle downstream of the filtration assembly, and an effluent collector adjacent to the filtration assembly and in fluid communication with the filtration assembly. The dewatering system includes a sensor to sense a characteristic of an influent, an effluent and/or a solid. A control system is operatively connected to the sensor to receive a sensor signal therefrom and to generate an adjustment signal based on the sensor signal to improve the efficiency of the dewatering system.

A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.

A modular, compact, mobile, dewatering and liquid-liquid separation and filtration system. The system processes incoming influents of slurries, solids and liquids at a high speed of operation and in large volumes. System is capable of being modularly scaled, allowing for a continuous steady state operation accommodating any slurry flow rate in a synchronous dynamic equilibrium process. Components and modules integrated into the system include a dynamic filtration clarifier 101 (DFC), a nested-filter dewatering cell 115 (NDC) and/or a compression filter press 125 (CFP). The DFC performs the primary dewatering phase of separating the primary water from the solids creating sludge. The NDC further breaks apart the solids of the sludge, removing interstitial water in a secondary dewatering phase, further lowering the moisture content of the sludge, while the CFP removes the tertiary water from the remaining solid particles by pressing the particles into a solid cake.
