摘要： Various methods of making a reinforced membrane, devices for making the membranes, and the resulting membranes are described. The methods typically provide a reinforcing structure that includes filaments extending around the circumference of the membrane but without the filaments being part of a braided or woven structure. Some of the reinforcing structures also include longitudinal filaments. The methods and devices can be used to make a supporting structure in line with membrane formation steps, and also allow for a reinforced membrane to be produced that has a ratio of inside-to-outside diameters of 0.5 or more.

摘要： An apparatus is described for withdrawing filtered permeate from a substrate contained in a reservoir at ambient pressure. The apparatus includes a plurality of membrane assemblies. Each assembly has a plurality of hollow fiber filtering membranes, immersed in the reservoir, at least one permeating header with the membranes sealingly secured therein, and a permeate collector to collect the permeate sealingly connected to the at least one permeating header and in fluid communication with lumens of the membranes. The membranes of each assembly extend generally vertically upwards from a first header during permeation. One or more sources of suction are provided in fluid communication with the lumens of the membranes of each assembly through the permeate collectors and apply sufficient suction to withdraw permeate from the lumens of the membranes. An aeration system for discharging bubbles assists in keeping the membranes clean. In other aspects, a method of removing fouling materials from the surface of a plurality of porous membranes includes providing, from within a membrane module, gas bubbles in a uniform distribution relative to the membranes. The bubbles move past the surfaces of the membranes to dislodge fouling materials from them. The membranes are arranged in close proximity to one another and mounted to prevent excessive movement.

摘要： A process of making a reinforced hollow fiber membrane comprises flowing a membrane dope through a casting head while drawing one or more yarns or tows of filaments through the casting head. The filaments are spread apart in the casting head, for example by forcing the yarns or tows around a bend or through a narrow gap in the casting head. The filaments are adapted to bond to the membrane dope or the membrane wall. A reinforced hollow fiber membrane comprises a plurality of filaments individually surrounded by, and bonded to, the membrane wall.

摘要： Disclosed is the method for creating a reinforced hollow fiber membrane by applying reinforcing filaments to a core, casting a dope over the filaments and core, forming a membrane from the dope, and removing the core. The core may be a moving core, and the reinforcing yarns may comprise warp yarns and a spiral wrap yarn. The core may be soluble and removed by dissolving it. The core may be pre-wrapped with a yarn before the warp yarns are applied. The resulting reinforcing cage may be pre-shrunk before it is coated with a membrane dope. The pre-wrapped yarn may be removed, for example by dissolving it, after the reinforcing cage is coated. A precursor assembly for making a hollow fiber membrane is also provided.

摘要： An element for use in ultrafiltration or microfiltration of potable water has a large number of small diameter hollow fibre membranes attached between two headers. Side plates attached to the sides of the headers define vertical flow channels containing the membranes. The elements may be placed side by side and stacked on top of each other to form cassettes having continuous vertical flow channels through the entire cassette. The membrane modules or cassettes may be arranged to cover a substantial part of the cross sectional area of an open tank. Tank water may flow upwards or downwards through the flow channels. A tank may be deconcentrated by at least partially emptying and refilling the tank with fresh water while permeation continues. Excess tank water created during deconcentration may flow generally upwards through the modules and out through a retentate outlet or overflow at the top of the tank.

摘要： This document describes a fermentation product producing or processing apparatus or process involving membrane pervaporation (PV) and either vapor permeation or distillation or both. The fermentation product may be produced semi-continuously wherein product concentration is maintained below a selected value by removal through pervaporation membranes. After a period of operation, the broth may be distilled. Distillation and/or pervaporation products may be further dewatered using vapor permeation. The PV membranes may be used in the form of immersed modules, for example with a flat sheet configuration.
