The present disclosure relates to a separating device for removing solid particles from fluids, and to the use of said separating device for removing solid particles from fluids.

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 lateral filter, a method of its use, and a system incorporating at least one lateral filter are provided. The lateral filter includes a filter screen that includes a screen wire and screen support rod comprise a non-metallic material and are a unitary, integrated, inseparable, and singular component. In using the lateral filter, a fluid entrained with solids is introduced through an exterior-facing side and permeate forms in the interior of the filter. The solids remaining in the permeate, if any, have a smallest dimension that is less than a width of a slot in the filter screen. The permeate passes from the interior of the lateral filter. Lateral filters may be incorporated into a system comprising many lateral filter, such as sand filter is configured to filter raw seawater.

A filter medium includes a plurality of layers each including an undulating strip of solidified material.

The present invention provides a multi plate screw press sludge dewatering machine and a helical shaft thereof. The multi plate screw press sludge dewatering machine includes fixed rings, movable rings, the helical shaft, a sludge inlet tank and a sludge discharging tank; the helical shaft adopts a variable diameter variable pitch helical shaft, a lead angle arrangement sequence of a helical blade of the whole helical shaft is gradual reduction from the sludge discharging tank to the sludge inlet tank, and the lead angle arrangement sequence is gradually reduced from 16°-22° to 6°-14°; a pitch of the helical shaft is gradually increased along a direction from the sludge inlet tank to the sludge discharging tank; a diameter of a shaft body of the helical shaft is gradually increased along with a direction of the sludge discharging tank from a ⅓ position of a shaft length; and blockage prevention plates are arranged on two sides of the bottom of the helical blade. The helical shaft in the present invention is specially designed, so that the pitch is more reasonable, a helical angle is gentler, frictional resistance when sludge passes through the helical shaft may be effectively reduced, and phenomena of shaft blockage and shaft sticking of the sludge may be reduced.

A filtering apparatus (100) having a filtering mode and a self-cleaning mode, the apparatus provided for filtering an upstream flowing fluid with filtering elements (20) in the form of a plurality of stackable discs during filtering mode utilizing a first flow direction, apparatus (100) also configured to self-clean the filtering elements (20) the apparatus (100) including an internal fluid diverter (110,210, 310) that is internal to the filter housing. The position of the internal fluid diverter determines the direction of fluid flow through the filter housing and the filter phase. The position of the internal fluid diverter is controlled with a controller disposed external to the filter housing that may be manipulated either manually or by automated means.
