摘要： The present invention relates generally to compositions for use in biological and chemical separations, as well as other applications. More specifically, the present invention relates to hybrid felts fabricated from electrospun nanofibers with high permeance and high capacity. Such hybrid felts utilize derivatized cellulose, and at least one non-cellulose-based polymer that may be removed from the felt by subjecting it to moderately elevated temperatures and/or solvents capable of dissolving the non-cellulose-based polymer to leave behind a porous nanofiber felt having more uniform pore sizes and other enhanced properties when compared to single component nanofiber felts.

摘要： A membrane is provided including a coating layer having cellulose nanofibers produced from oxidized cellulose microfibers and an electrospun substrate upon which the coating layer is applied. The nanofibers of the electrospun substrate have a diameter greater than that of the cellulose nanofibers. The membrane also has non-woven support upon which the electrospun substrate is disposed. Microfibers of the non-woven support have a diameter greater than that of the nanofibers of the electrospun substrate. Application of electrospun membrane is in microfiltration area, while the cellulose nanofiber membrane serves in ultra-filtration, nanofiltration, and reverse osmosis after chemical modification.

摘要： A composite filter media includes a base sheet incorporating polymer microfibers and nano-fibrillated cellulose in combination with one or more alternative upstream depth filtration layers. Embodiments of the composite filter media employ polymer or fiberglass layers arranged on the upstream face of the base sheet. A lightweight protective spun bond scrim may be applied to the upstream face of the upstream depth filtration material. The depth filtration layer or layers may be laminated to each other and/or the base sheet or co-pleated with the base sheet to form the disclosed composite media. The depth filtration layers are configured to provide a positive density gradient in the direction of fuel flow through the composite media, meaning that the depth filtration media increases in density and decreases in pore size in the direction of fuel flow.

摘要： The present invention relates to a filter comprising a carbon block enveloped with spiral wound layer of non-pleated fabric enveloped with spirally wound layer of pleated fabric. The combination of these three elements gives more than 3.5 log cyst removal from contaminated water, over prolonged usage of more than 2300 liters of water. The invention also relates to a gravity filtration device that comprises the filter of the invention. A method of filtering water is also claimed where the water flows first through the pleated fabric, then through the non-pleated fabric and then through the carbon block.
