Hollow fiber membranes (HFMs) are a class of artificial membranes containing a semi-permeable barrier in the form of a hollow fiber.
Originally developed in the s for reverse osmosis applications, hollow fiber membranes have since become prevalent in water treatment, desalination, cell culture, medicine, and tissue engineering. Most commercial hollow fiber. Filtrate Connectors for UF Membranes. Our hollow fiber UF membranes can be used in standard housings with the appropriate Filtrate Connectors as listed below.
Please choose the appropriate connectors below to adapt the hollow fiber elements to the vessel you will be using. (Two connectors are required per pressure vessel.). Hollow Fiber Membrane Module. Cite this entry as: () Hollow Fiber Membrane.

Characterization of hollow fiber membranes by impedance spectroscopy Article in Journal of Membrane Science – January with Reads How we measure 'reads'. Hollow Fiber Membranes for Photosensitized Electron Transport book reciprocating guide loops the hollow fiber membranes alternatively onto two spider shaped spokes as shown in Fig.
The spokes pick up the hollow fibers and hold them in place which eliminates the need for a central tube. Notably, more than one type of hollow fiber membranes could be wound together to form a by: The work described in this paper is part of a joint European program.
The ultimate goal of this program is the development of a hollow fiber membrane system for the separation of olefins from paraffins. One of the aims is the delivery of a pilot scale hollow fiber module (> m 2 membrane area). Since the development of such a module requires Cited by: Hollow Fiber Membranes Cartridge Information Description and Use GE ultra˜ltration (UF) and micro˜ltration (MF) mem-brane cartridges are provided with a wide range of hollow ˜ber and tubule lumen diameters, mem-brane pore sizes, surfac e areas and dimensions.
Each cartridge contains a bundle of polysulfone ˜bers or tubules potted in. Ultrafiltration UF Systems with Hollow-Fiber UF Membranes Applied Membranes, Inc. Ultrafiltration (UF) membrane treatment systems are designed to produce clean, purified water from various sources waters, including rivers, lakes, industrial ponds, secondary effluent, well water, and seawater.
A Hollow fiber bioreactor is a 3 dimensional cell culturing system based on hollow fibers, which are small, semi-permeable capillary membranes arranged in parallel array with a typical molecular weight cut-off (MWCO) range of kDa.
These hollow fiber membranes are often bundled and housed within tubular polycarbonate shells to create hollow fiber bioreactor cartridges. Polyvinylidene fluoride hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively.
Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness, and water contact by: Oxygen transport hollow fiber membranes with the composition BaSrCoWFeO3 − δ were used to demonstrate the possibility of their heating to operating temperature by passing the.

The PVDF hollow fiber membranes were prepared by non-solvent-induced phase separation (NIPS) through spinning equipment, as shown in Figure 1. Table 1 lists the spinning parameters.
Casting dopes were prepared by adding PEG ( Da) into the solvent, including PVDF, 1,4-diethylene dioxide and N,N-dimethylacetamide Cited by: Comparison of Membrane Technology. There are different types of membranes available for use in MBR's: Tubular, Hollow Fiber and Flat Sheet.
Below is a comparison of the technologies. Tubular Membranes. Tubular membranes were available for laboratory use as early as the 's and were first used in industrial applications in the 's. Hollow Fiber Element - Hollow fiber elements represent one of four possible RO membrane configurations (others configurations are spiralwound, plate and frame, and tubular).
Hollow fiber elements are made of extruded cellulose acetate or polyamide material. Pressurized feed water passes across the outside of the fibers. Hollow Fiber Membrane Technology. Prime water produces a super-efficient hollow fiber membrane, which has a high affinity for water and only needs low pressure to start the filtration ble in micro and ultra filtration versions, it delivers high flow rates at a low pressure gradient, with low energy consumption as an added benefit.
At this temperature, the porosity of the nickel hollow fiber support and the nickel hollow fiber membrane shows 38% and 34%, respectively. Fig. 7 gives the pore size distribution from the nickel hollow fiber support sintered at C for 3 h, as well as the nickel hollow fiber membrane sintered at C for 1 h.

The excellent mass-transfer properties conferred by the hollow fiber configuration soon led to numerous commercial applications in various field such as the medical field (blood fractionation), water reclamation (purification and desalination), gas separation, azeotropic mixture separation (using pervaporation).
The prepared membranes were characterized by SEM, EDX, XRD and gas permeation techniques. Effects of the starting ZrO 2 particle size and sintering temperature on the physical properties of the resulted hollow ﬁber membranes were extensively studied.
Sintered at C for 10h, membranes made from 80nm sized ZrO. In this study, hydrophilic PTFE hollow fiber membranes were prepared and applied for CO2 desorption via a membrane flash process, which is a new CO2 desorption process by utilizing waste thermal energy. The methyldiethanolamine was selected as the absorbent.
