Abstract: A filter media, filter element, filter system and methods are provided. The filter media provides improved filter characteristics including water separation efficiency. The filter media may include one or more of increased surface roughness and/or embossments. The filter media may be provided by pleated filter media.

Abstract: A filter cartridge includes an open-ended housing and filter element supported in the housing and defining an annular region between a periphery of the filter element and a side housing wall. A water collection region is between an end of the filter element and a lower-housing wall. The filter element includes pleated media surrounding an axially-extending central area, and pleats of different heights round the central area. An end plate is bonded to the filter element to prevent fluid flow through the pleats' upper ends. One passage is through a plate opening into the central area. Another passage is between the end plate and peripheral region. The filter element has freely-supported lower ends. A seal between the lower periphery of the filter element and the housing prevents fluid bypass of the filter element. Fluid passes through the pleats, and water coalesces on the media and drains into the collection region.

Abstract: Methods, compositions, single phase aqueous solutions, process mixtures, and kits are provided relating to recycling a fibrous surface covering, e.g., carpet, using a single-phase aqueous solution. For example, a method of recycling a fibrous surface covering may include providing the single phase aqueous solution. The single phase aqueous solution may include water and a surfactant composition. The method may include providing the fibrous surface covering. The fibrous surface covering may include: a fibrous surface layer; a first backing coupled to the fibrous surface layer; and a binder coupled to one or more of the first backing and the fibrous surface layer. The method may include contacting the single phase aqueous solution and the fibrous surface covering to form a process mixture under conditions effective to provide a recycled portion of the fibrous surface covering.

Abstract: Compositions, process mixtures, methods, and kits are provided for removing one or more coatings from a polymeric substrate, e.g., corrugated polymeric substrates, using a single-phase aqueous solution. The single-phase aqueous solution may include, for example, water; an inorganic base composition; a sulfoxylate composition; and a surfactant composition.

Abstract: Methods, compositions, single phase aqueous solutions, process mixtures, and kits are provided relating to decolorizing post-consumer fibers, e.g., from carpet pile, using a single-phase aqueous solution. For example, a method of decolorizing post-consumer fibers may include providing the single phase aqueous solution. The single phase aqueous solution may include water, a stable peroxygen composition, and a surfactant composition. The method may include providing the post-consumer fibers comprising a colorant. The method may include contacting the single phase aqueous solution and the post-consumer fibers to form a process mixture under conditions effective to provide a decolorized portion of the post-consumer fibers.

Abstract: A film treatment system includes a mill tank, a shaft, and a milling blade. The mill tank contains coated polymeric material in comminuted form, and further contains an aqueous solution for removing coating material from the polymeric material. The shaft is supported for rotation about a vertical axis in the tank. The milling blade is supported on the shaft for rotation with the shaft, and has a leading surface reaching radially outward with a convex contour facing in a rotationally forward direction.

Abstract: A coated polymeric film is comminuted, and is advanced between successive processing stations in a coating removal system in a stream of conveyance fluid driven through a conduit reaching between the successive processing stations.

Abstract: Methods, compositions, single-phase aqueous solutions, process mixtures, and kits are provided relating to recycling a pressure-sensitive adhesive laminate using a single-phase aqueous solution. For example, a method of recycling a pressure-sensitive adhesive laminate may include providing the single-phase aqueous solution. The single-phase aqueous solution may include water and a surfactant composition. The method may include providing the pressure-sensitive adhesive laminate. The pressure-sensitive adhesive laminate may include: a facestock including a label surface and an adhesion surface; a release liner including a release surface; and a pressure-sensitive adhesive coated on the adhesion surface of the facestock, the release surface of the release liner being laminated to the adhesion surface of the facestock through the pressure-sensitive adhesive.
