Abstract: An apparatus for fabricating a graphene membrane includes a first section having a first fluid chamber for housing a suspension of graphene platelets in a fluid. A second section is positionable adjacent the first section. The second section has a second fluid chamber and a porous support housed in the second fluid chamber for supporting a porous substrate. When the first section is positioned adjacent to the second section and the porous substrate is supported by the porous support, the first fluid chamber and the second fluid chamber are in fluid communication via the porous substrate. The apparatus further includes a pressurizer for creating a pressure differential between the first fluid chamber and the second fluid chamber and thereby forcing the fluid through the porous substrate and into the second fluid chamber and lodging the graphene platelets in the pores of the porous substrate.

Abstract: A specially functionalized composite filter material with a high specific surface area is used to adsorb PFAs from potable water. In a preferred embodiment, the base filter material is granular activated carbon (GAC), which is sequentially coated with a thin layer of polydopamine, a thin layer of partially oxidized iron, and a thin coating of octadecylamine. After PFAs are adsorbed onto the coated GAC particles, the PFAs are removed by a rinsing process, and remain in the rinse effluent. GAC particles are recovered and recoated as needed to restore their adsorptive capacity. The PFA-containing effluent is treated using photochemical processes to destroy the PFA molecules. The now PFA-free effluent can be disposed of as a non-hazardous material. The composite filter material works in systems ranging from small passive systems for personal use to large scale, high-flow-rate utility water treatment systems.

Abstract: A cartridge comprising layers of adsorbent sheet is described. The cartridge includes an indicator that characterizes the consumption state of the adsorbent within the cartridge. The indicator is applied in a way such that discrete areas of indicator are visible. These discontinuous areas of indicator may be applied to the outside surface of the cartridge. Alternatively, the discontinuous areas may be formed by cutting windows in the outermost layer of the cartridge and either coating indicator on the layer beneath the window, placing an indicator layer between the window and the layer beneath it or filling the window with an indicating plug of material so that the indicator is visible from the outside of the cartridge. The indicator layer and indicator plug embodiments allow the use of any indicator with any adsorbent.

Abstract: The present disclosure provides a system, method, and apparatus for detecting chemical effluents in an environment using Teslin substrates. To illustrate, a system includes one or more Teslin substrates which can capture molecules present in an ambient environment. The system includes a housing with the one or more Teslin substrates disposed within the housing. The system further includes means for selectively exposing different portions of the one or more Teslin substrates to the ambient environment, in which the molecules present in the ambient environment are captured by the different portions of the one or more Teslin substrates as the different portions of the one or more Teslin substrates are exposed. The system can include that the means for selectively exposing different portions of the one or more Teslin substrates is an aperture in the housing.

Abstract: Bleached polycrylic acid crosslinked cellulose fibers with reduced furfural content are disclosed. The reduced furfural content is accompanied by a strong reduction of malodor associated with crosslinked fibers. Methods of furfural reduction include treatment with hydrogen peroxide in the absence of alkaline or other bleaching agents subsequent to curing polyacrylic acid crosslinked cellulose fibers. Some embodiments of treated polycrylic acid crosslinked cellulose fibers have a furfural content lower than 1.3 ppm. In some embodiments, the reduction of furfural content of the treated crosslinked fibers compared to untreated crosslinked fibers is at least 55%. in some embodiments, furfural content decreases with aging of the treated crosslinked fibers.
