Abstract: A filter medium comprising a body of the filter medium having the space thereof partitioned three-dimensionally, irregularly and manifoldly by bent linear members having a strength sufficient to cause substantially no substantial deformation when the filter medium is actually used, and an effluent pipe connected to the body of the filter medium, said effluent pipe having an opening located in the interior of the body, from which a filtrate flows out, is disclosed. When at least one component is filtered or separated from a material to be treated by filtrate the dispersion medium as the filtrate is interposed between a filter cake and the surface portion of the body of the filter medium and the dispersion medium as the filtrate is allowed to pass very easily through the filter cake. Accordingly, clogging is not caused in the filter medium and the filtration can be performed at a substantially uniform flow rate throughout the operation. In addition, a process for the preparation of such filter medium and a filtering method and apparatus using such filter medium are provided. This filter medium can be effectively used in any field for separating components from dispersions, for example, separating oils from water.

Abstract: A filter assembly including a housing with a plurality of individual filter units circumferentially arranged within the housing. The housing is compartmented to channel a contaminated fluid to be filtered in a filtering direction through the filter units, from one end thereof to the other. A rotatable, conduit-like backwash arm is disposed in at least one end of the housing for sealed engagement with the contaminated fluid inlet, end of a filter unit and for receiving a backwashing fluid flow therefrom. A rotatable discharge pipe connects to the outlet end of the arm and extends from the housing through a rotary-axial bearing and seal unit thereon, and is coaxially arranged with respect to the circumferential array of filter units. A rotation indexing unit adjacent the housing engages the discharge pipe for angularly shifting said backwash arm from filter unit to filter unit and thereby for backwashing of said filter units in a desired sequence. An axial shift unit engages the discharge pipe for axially shifting the backwash arm away from the filter units preparatory to each angular shift, and for axially shifting the backwash arm into sealed engagement with a new filter unit following such an angular shift. A control coordinates actuation of the rotational indexing unit and axial shift unit for sequentially backwashing filter units of the array. In a modification, a rotatable backwash arm is provided at each end of the array of filter units, movement of the arms being synchronized and the arms being axially opposed for sequentially backwashing the filter unit with a backwashing fluid other than the filtered fluid. In a further modification, the axial shift unit comprises a camming device directly responsive to rotation of the discharge pipe for carrying out the axial shifting of the backwash arm.

Abstract: The invention provides a method and apparatus for removing suspended solids from liquids. In carrying out the method, a liquid containing suspended solids is delivered to a screen with a directional component across the screen surface and a directional component through the screen. The screen has openings that are large enough to pass a majority of the suspended solids, and the screen has the ability to hold a layer of the solids on the upstream side thereof. The flow of the liquid is controlled so that the coating is formed and maintained on the screen, and serves as a filtration medium. The invention also provides improved apparatus which comprises means defining a liquid filtration zone having a screen separating it into influent and effluent zones. The screen has openings large enough to pass the majority of suspended solids and has the ability to hold a layer of the solids on the upstream side. Means are provided for delivering liquids and suspended solids to the screen with a directional component parallel to the face of the screen and a directional component through the screen.

Abstract: A filter tube for use in earth coated type filters includes a flexible permeable tubular sheet internally supported by a helical spring. The internal spring is connected between opposite ends of the filter tube to support the full length of the tube wall. One end of the tube is connected to an external spring and anchor plate. In a slack position, the tube end folds over an end collar connected to the spring. Extension of the anchor plate applies tension to stretch the spring and tube to a taut position during a cycling operation which oscillates the tube to dislodge accumulated material.
