Fluid treatment arrangements and elements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. Two or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Posts may be located in some of the spaces and may be bonded to the adjacent fluid treatment elements. Bands may encircle some of the spaces to block radial fluid flow into or out of the spaces.

Fluid treatment elements and fluid treatment arrangements with posts and/or bands between fluid treatment elements and methods for making and using them

Fluid treatment arrangements having at least first and second radially displaced sets () of fluid treatment elements and methods for making and using them are disclosed: A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element of either set. At least two and as many as fifty or more fluid treatment elements (&#x2033;) may be positioned along a hollow core assembly () in each set. Fluid may be directed to or from the interior of the core assembly through a fluid treatment element of the first set and a fluid treatment element of the second set. In each fluid treatment element, fluid flows generally edgewise through the permeable fluid treatment medium.

Fluid treatment arrangements with sets of fluid treatment elements and methods for making and using them

Fluid treatment arrangements and methods for making and using fluid treatment arrangements are disclosed. A ribbon including a permeable fluid treatment medium may be spirally wound in a plurality of windings to form a fluid treatment element having a disk-shaped body. For some embodiments, the ribbon may comprise a composite having first and second layers. At least two and as many as many as fifty or more fluid treatment elements may be positioned along a core assembly with spaces between at least some of the adjacent fluid treatment elements. Many, most, or substantially all of the spaces may be substantially free of structure. A fluid treatment arrangement may be contained in a housing to form a fluid treatment assembly. The housing may include an inlet port and an outlet port and may define a fluid flow path between the inlet port and the outlet port. The fluid treatment arrangement may be positioned in the housing across the fluid flow path.

Fluid treatment elements and fluid treatment arrangements with spaces between fluid treatment elements and methods for making and using them

Fluid treatment arrangements and methods involve a plurality of fluid treatment modules and a core assembly that extends through the plurality of fluid treatment modules. Each fluid treatment module has a feed region, a permeate region, and a fluid treatment medium separating the feed region from the permeate region. The feed region extends along a feed surface of the fluid treatment medium, and the permeate region extends along a permeate surface of the fluid treatment region. Feed fluid is directed along the feed region of each module, and a portion of the feed fluid passes as permeate through the fluid treatment medium, into the permeate region, and then into the core assembly. One or more control mechanisms are fluidly coupled to the permeate region of one or more fluid treatment modules to control a flow parameter in the permeate region of the module.

Fluid treatment arrangements and methods

Fluid treatment arrangements and methods involve a spirally wound fluid treatment pack. The fluid treatment pack includes a fluid treatment medium, a feed region, and a permeate region. The feed region extends along a feed surface of the fluid treatment medium and the permeate region extends along a permeate surface of the fluid treatment medium. The fluid treatment pack is spirally wound around a core assembly to form a plurality of windings of the feed region, a plurality of windings of the fluid treatment medium, and a plurality of windings of the permeate region.

A fluid treatment element comprises a fluid treatment pack including a fluid treatment medium. The fluid treatment pack has a hollow interior and a barrier is disposed in the hollow interior. The barrier separates a blind region in which fluid cannot flow between the hollow interior and the fluid treatment pack from an open region in which fluid can flow between the hollow interior and the fluid treatment pack and prevents fluid from flowing between the blind region and the open region. The fluid treatment pack also has an end region having a sealed end. The fluid treatment element defines a flow path for process fluid to be treated passing in a lengthwise direction through a portion of the fluid treatment pack.

Fluid treatment elements

A fluid treatment element is adapted for cross flow filtration which includes a fluid treatment pack having first and second lengthwise ends, a fluid treatment layer that may be pleated, a first mesh layer disposed on a first side of the fluid treatment layer and a second mesh layer disposed on the second side of the treatment layer, the element defining a flow path for a process fluid to be treated passing in a lengthwise direction of the fluid treatment element inside the first mesh layer and a flow path for permeate passing through the second mesh layer. The first mesh layer may open onto the first lengthwise end with the second mesh layer including sealant at the first lengthwise end such that fluid can flow through the first lengthwise end into the first mesh layer but not into the second mesh layer. The element may include a core having a blind region in which fluid cannot pass therethrough and at least one regions where fluid can pass through the core.

Fluid treatment elements adapted for cross flow treatment

A method for removing iron-containing contaminants from condensate from a power generating plant includes passing the condensate through a plurality of pleated filter elements contained within a housing, including direct the condensate through a pleated hydrophilic film comprising ultra-high molecular weight polyethylene. The invention is capable of removing fine particulate matter and provides long filtration cycles between backwashing.

Method for separating solid particulates from a liquid

A filter capable of being used in subterranean environments includes a filter medium. An erosion barrier is disposed along a common flow path with the filter medium for preventing erosion by particles in a fluid being filtered.

Filter for subterranean use

The present invention provides a filter sealing device for a filter element. The filter element includes an end portion defining an opening. The sealing device includes a body having a first section attached to a second section. The first section is positionable within the opening in the filter element with the second section facing an open end portion of the filter element. The first section has a larger coefficient of thermal expansion than the end portion of the filter element so that an increase in temperature results in the first section of the body expanding at a greater rate than the end portion of the filter element. These differing rates of expansion cause a compressive force to be exerted between the first section of the body and the end portion of the filter element.
