A water purification cartridge includes a casing with a tubular shape that has an inflow portion for raw water to flow in and an outflow portion for purified water to flow out, and a filter member for filtering the raw water, the filter member being accommodating within the casing. The filter member is formed to have a cylindrical shape having a hollow portion, and has a first face and a second face at respective ends in an axial direction. The casing has a first cover portion, a second cover portion, and a side wall portion. The first cover portion covers the first face. The second cover covers the second face. The side wall portion covers an outer circumferential face of the filter member. In the first cover portion, a first contact portion is formed that annularly comes into contact with the first face and that press the filter member in the axial direction to elastically deform the filter member. In the second cover portion, a second contact portion is formed that annularly comes into contact with the second face and that press the filter member in the axial direction to elastically deform the filter member.

A monolithic swing bed absorption apparatus including a first bed. The first bed including a bed housing including a first side and a second side, a first manifold section extending from the first side to the second side within the bed housing, a filtration section extending from the first side to the second side within the bed housing, and a second manifold section extending from the first side to the second side within the bed housing. The filtration section being interposed between the first manifold section and the second manifold section. The monolithic swing bed absorption apparatus is a single piece including a unitary structure.

A porous carbon material wherein a particle diameter is 10 μm or more but 1 cm or less; wherein a bulk specific gravity is 0.20 g/cm.sup.3 or more; and wherein a mesopore volume is 0.10 cm.sup.3/g or more.

A hollow fiber that generally extends in a longitudinal direction is provided. The hollow fiber comprises a hollow cavity that extends along at least a portion of the fiber in the longitudinal direction. The cavity is defined by an interior wall that is formed front a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains. A porous network is defined in the composition that includes a plurality of nanopores.

Disclosed is a filter for a water-purification device, the filter including a filter housing having a water inlet and a water outlet defined therein; and a filter member disposed in the filter housing to purify water introduced through the inlet and supply the purified water to the outlet, wherein the filter member includes a carbon block produced by mixing 40 to 50% by weight of titanium oxide, 30 to 40% by weight of activated carbon, and 18 to 23% by weight of binder with each other. Further, a water-purification device including the filter is disclosed.

A remedial composition is disclosed made from plant material residue that has been densified and then reduced into discrete pieces with a bulk density of from about 0.2 g/cm.sup.3 to about 0.5 g/cm.sup.3. The composition can be made from various different plant species and can be particularly made from agricultural crop byproducts, such as flax shives. The composition is particularly well suited for use as a remediation product for cleaning up and/or removing oily substances, such as petroleum products.

Bare porous polymer monoliths, fluidic chips, methods of incorporating bare porous polymer monoliths into fluidic chips, and methods for functionalizing bare porous polymer monoliths are described. Bare porous polymer monoliths may be fabricated ex situ in a mold. The bare porous polymer monoliths may also be functionalized ex situ. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include inserting the monoliths into channels of channel substrates of the fluidic chips. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include bonding a capping layer to the channel substrate. The bare porous polymer monoliths may be mechanically anchored to channel walls and to the capping layer. The bare porous polymer monoliths may be functionalized by ex situ immobilization of capture probes on the monoliths. The monoliths may be functionalized by direct attachment of chitosan.

Various hydrogels are described which are useful for the regeneration of methyldiethanolamine which is used to scrub H.sub.2S/CO.sub.2. Methods of regenerating methyldiethanolamine using such hydrogels are also described.
