An example water well submersible pump filter may comprise: (1) a perforated cap; (2) a hollow cylindrical middle member joined to the perforated cap at a first end of the hollow cylindrical middle member, wherein the hollow cylindrical middle member comprises a perforated hollow cylindrical segment proximate to the first end of the hollow cylindrical middle member; and (3) a filter crown joined to a second end of the hollow cylindrical middle member, wherein the filter crown comprises a ring of fins extending approximately parallel to an axis of the hollow cylindrical middle member.

A filter assembly comprising a prefiltering support layer (84) is disclosed, wherein the prefiltering support layer (84) comprises a non-woven fabric of fibers, the non-woven fabric having a pore size. A first mesh filter layer (85) is arranged downstream the prefiltering support layer (84), wherein the first mesh filter layer (85) has a first mesh size, wherein the pore size of the prefiltering support layer (84) is equal to or bigger than the first mesh size of the first mesh filter layer (85). A container for collecting a body fluid comprising such a filter assembly as well as a method for manufacturing such a filter assembly are also disclosed.

A filter and filter media configured and arranged for placement in a fuel stream is disclosed. The filter and filter media allow for filtering of liquid fuels, such as diesel fuel. In certain embodiments the filter media includes a media fiber (such as glass) and a binder fiber (such as bicomponent) that combine to create a media structure having low solidity and relatively low compressibility, and which contain a pore structure that avoids premature fouling of the filter by fuel degradation products.

Provided are certain composite membranes useful for removing various impurities from liquids. In certain aspects, the composite membranes comprise a hydrophobic polymer having a polyamide coated thereon, and in other aspects, such composite membranes having certain acrylic polymers coated thereon. The composite membranes are useful in the removal of various impurities in liquids, such as those encountered in industrial and life sciences processes.
