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 it. The comb-holder arms are connected to the auger shaft by means of an epicyclic secondary gear.

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 in (9.5 mm) sieve, and <3.5% by dry weight of inert or foreign man made materials.

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 method of separating solids from a slurry or suspension is disclosed. The method includes: providing a slurry or suspension containing solids and liquid to an input port of a first side of a filter, the filter providing a filtering size between 2 microns and 70 microns; providing a liquid discharge port on a second side of the filter which receives the liquid that passes through the filter; and separating the solids from the liquid by pressing the solids into a pressure regulating solids discharge port on the first side of the filter, thereby compacting solids on the first side of the filter, forcing at least some of the liquid of the slurry or suspension through the first side of the filter to the second side of the filter causing pressure regulated solids to be discharged through a pressure regulating solids discharge port into a pressurized chamber.

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 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.

The present disclosure may include a press screw separator configured for separating solid components from a slurry containing solid and liquid components. The separator may include a housing, a frame arranged in the housing, and a cylindrical screen which is arranged at least partially in the frame. The separator may also include a screw adapted for pressing out the slurry, which screw may be arranged within the screen and mounted so as to be rotationally movable about a longitudinal axis of the screen. The frame may be mounted in the housing without any clearance.

A method of separating solids from a slurry or suspension is disclosed. The method includes: providing a slurry or suspension containing solids and liquid to an input port of a first side of a filter, the filter providing a filtering size between 2 microns and 70 microns; providing a liquid discharge port on a second side of the filter which receives the liquid that passes through the filter; and separating the solids from the liquid by pressing the solids into a pressure regulating solids discharge port on the first side of the filter, thereby compacting solids on the first side of the filter, forcing at least some of the liquid of the slurry or suspension through the first side of the filter to the second side of the filter causing pressure regulated solids to be discharged through a pressure regulating solids discharge port into a pressurized chamber.

Devices, systems, and methods for concentrating a slurry are disclosed. A concentrator is utilized, including a cylindrical vessel containing a cylindrical filter and a screw. The cylindrical filter consists of a plurality of spaced annuli. The screw passes through the cylindrical filter. A slurry passed through the cylindrical vessel is concentrated. The slurry is conveyed by the screw along an interior of the cylindrical filter. Any two concentric annuli are spaced such that the solid is prevented from passing between them. The slurry is concentrated to produce a concentrated slurry by restricting the product outlet such that a back pressure is created in the cylindrical vessel. The back pressure causes a portion of the liquid to pass between the annuli and out a fluid outlet. The concentrated slurry passes out a product outlet.

A vertical separator for the treatment of slurry. The vertical separator comprises: 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; and a discharge device for the solid particles. The screen device houses a counter-pressing device (e.g. a screw, which is designed to generate a reaction, which partially counters the pushing action exerted by the pump upon the slurry.
