摘要： A membrane filter module configured to treat a liquid contained in a tank at an ambient pressure. The module may have a header, with a bundle containing a plurality of substantially vertical hollow fiber membranes, wherein a lower end of each hollow fiber membrane is fixed in the header. The module may also have a gasification device adapted to periodically generate a gaseous bubble and configured to release the gaseous bubble within the bundle. The module may further have an enclosure that substantially surrounds the bundle that extends from a lower region to an upper region of the membrane bundle, wherein the enclosure is configured to retain the liquid introduced into the enclosure such that the liquid surrounds the membrane bundle. The gaseous bubble has a cross-sectional area that corresponds with a cross-sectional area of the enclosure, such that the cross-sectional area of the gaseous bubble occupies substantially the entire cross-sectional area of the enclosure as it flows along the bundle.

摘要： A process for producing high quality reverse osmosis, nanofiltration, and ultrafiltration membranes in a high speed process provides membranes which have excellent rejection characteristics coupled with high flux capabilities. The process employs tandem coating techniques to coat a microporous substrate with a thin membrane on the order of 25 .ANG. to 1.0 microns. The tandem coating process comprises tandem offset gravure and subsequent slot die coating applicators, or alternatively comprises tandem slot die coating applicators. For reverse osmosis and nanfiltration membranes, a wet-on-wet coating process is used to coat a porous substrate first with an aqueous solution, and then with an organic solution to produce a cross-linked, interfacially polymerized composite membrane. Single slot coating applicators are utilized to produce ultrafiltration membranes.

摘要： A method for preparing a spiral wound filtration module is provided. The module has a central permeate carrier tube. The method includes winding at least one filtration leaf about the permeate carrier tube. The filtration leaf includes a first membrane sheet, a permeate carrier sheet, and a second membrane sheet. The winding step creates an end face extending radially outwardly from the permeate tube on each end thereof. After winding, the filtration module is maintained in a wound state. An adhesive is then supplied to each end face and a vacuum is applied through each of the permeate tube. While the vacuum is applied, the permeate tube and filtration leaf assembly are spun in a centrifuge until the adhesive has solidified. After spinning, each end face of the module is severed at a distance between the level of adhesive along the feed spacer screen and the level of adhesive along the permeate carrier sheet.

摘要： An epoxy or trimethylene ether-direct grafted halogeneated vinyl polymer is prepared by the reaction of an epoxide such as a 5-ethyl, 5'-methyl-hydantoin/epichlorogydrin condensation product with a halogenated vinyl polymer such as polyvinylidene fluoride in the presence of a metal halide catalyst. The ether residue of the epoxide is grafted directly to the first carbon-chain carbon of the halogenated vinyl polymer. The graft polymer compositions are utilized as ultrafiltration and reverse osmosis membranes.

摘要： A spirally wound, high flux membrane module which comprises a feed inlet, a concentration outlet and two permeate outlets and one or more membrane leaves wrapped about a central permeate flow tube to define a permeate flow path in one or more of the membrane leaves and wherein the improvement comprises one or more of the membrane leaves containing two or more separate permeate flow compartments within the membrane leaf to provide for the separate permeate flow of the permeate within the separator compartments to the permeate outlet thereby reducing the area of the permeate back pressure and reducing membrane wrinkling and membrane failure particularly during the membrane cleaning cycles. A method of reducing permeate back pressure within a spirally wound membrane module, which method comprises subdividing the permeate flow path in one or more of the spirally wound membrane leaves into two or more separate permeate flow compartments to provide for the separate radial permeate flow of the permeate to the permeate central tube and permeate outlet.
