Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel. A combustor vessel is configured to receive a solids component from the extrusion plate. A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

A reciprocating lamination spiral solid-liquid separator is provided, including: a support frame, a filter chamber, a spiral shaft and a driving device. The filter chamber is assembled with the support frame. The spiral shaft is mounted on the support frame and passes through the filter chamber. The driving device is mounted on the support frame. Two ends of the filter chamber respectively have a feed port and a discharge channel. The filter chamber includes a first closed movable ring-piece assembly and a second closed ring-piece assembly having a motion state that is inconsistent with that of the first closed movable ring-piece assembly. The first and second closed ring-piece assemblies are stacked alternately to form the filter chamber, and a gasket is disposed between two adjacent closed ring-pieces of one of the closed ring-piece assemblies.

In a solid-liquid separation apparatus, which comprises multiple movable members and screws that extend and pass through the movable members without contacting the movable members and which dehydrates sludge while conveying same by means of the rotation of the screws, to apply a wringing action on the sludge and increase sludge dehydration efficiency. (Solution) A first movable unit 41 is configured by linking multiple movable members 4A and 4B as a unit with a linking rod 44, a second movable unit 41A is configured by linking multiple other movable members 4C and 4D as a unit with a linking rod 44A, and the movable members 4A and 4B of the first movable unit 41 and the movable members 4C and 4D of the second movable unit 41A are reciprocated with a phase difference.

A vertical separator for the treatment of slurry includes a screen device with a vertical axis provided with a screen, a feeding device provided with a pump to feed the slurry to a screen device, a discharge device for the liquid part of the slurry, and a discharge device for the solid particles of the slurry. The screen device houses a counter-pressing device which is designed to generate a force which partially counters the pushing action exerted by the pump upon the slurry.

The present disclosure relates to a separation device to separate contaminants from contaminated water. It comprises a container to receive the contaminated water. The container further comprises a contaminated water inlet, a filter, a presser for compressing and/or dewatering contaminants separated from the contaminated water, and a contaminant outlet. The container further comprises a gas inlet for generating gas bubbles into the contaminated water to further separate contaminants from the contaminated water. The present disclosure relates to a use of such a separation device and a method of separating contaminants from contaminated water.

A hybrid filtration sock comprises a mesh tube filled with a blended filler comprising 60%-90% fibrous volumizing filler and 10%-40% woody organic filler. The fibrous volumizing filler 12 includes straw, grasses, pine straw, corn stalks, natural fibers and weeds and combinations thereof. The woody organic filler is ground or chipped wood based material from land clearing, yard waste, pallets and clean wood debris or clean wood scraps, comprising a PH of between 5.0 and 8.0, with a particle size wherein 99% passes a 2 in (50 mm) sieve and a maximum of 43% passes a ⅜ in (9.5 mm) sieve, and <3.5% by dry weight of inert or foreign man made materials.

An apparatus for wastewater filtration having a barrel, a basket and a screw on a shaft rotating therein for pushing solid in a distinct output. A removable cartridge comprises a cover for the barrel, the cartridge comprising a pre-sealed shaft connector which releasably connects to at least the upper shaft portion or the lower shaft portion to form the shaft. The screw comprises a brush on an outer rim thereof, the brush having radially outwardly oriented bristles that scrape an inner surface of the basket. The screw comprises a winged wiper at a bottom thereof for sweeping a bottom surface of the barrel, and the solid-material output is provided at the bottom surface of the barrel and is shaped as a rectangular opening which is offset from a central axis of the screw. Solid removal efficiency and maintenance are thereby improved.

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 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.
