Hydraulic permeability of hollow‐fiber membranes
Journal of Biomedical Materials Research, 1978AbstractTwo experimental methods have been developed to characterize the pressure‐driven flow of a liquid through the walls of single hollow‐fiber membranes. In one method, the permeation rate is measured directly by following the air–water interface in a pressurized pipet connected to a hollow fiber which is sealed at one end.

Omniphobic Hollow-Fiber Membranes for Vacuum Membrane Distillation
Environmental Science & Technology, 2018Management of produced water from shale gas production is a global challenge. Vacuum membrane distillation (VMD) is considered a promising solution because of its various advantages. However, low-surface-tension species in produced water can easily deposit on the membrane surface and cause severe fouling or wetting problems.

Virus concentration using hollow fiber membranes—II☆
Water Research, 1975Abstract A cellulose acetate hollow fiber membrane permeator was used to concentrate polio-l virus from 51. of water. The objective of the study was to evaluate the effect of several independent variables—radial flow direction, feed flow rate. feed concentration. cell type and effectiveness of backwashing—on process performance.

Membrane technology has been successfully applied in many different industrial fields and in some of them, such as desalination, it can be considered a dominant technology. Membranes are produced using a wide variety of techniques which mainly depend on the membrane material employed and on the applications.

Blood Purification, 1986
Polyether-polycarbonate hollow fibers, spun by the phase inversion method, yield a dialysis membrane with a limited ultrafiltration coefficient but high diffusive permeability. Dialysers are made out of this membrane and are sterilized by gamma radiation.

Capillary hollow fiber nanofiltration membranes
Separation and Purification Technology, 2001Spiral-wound modules generally have high packing densities, low costs, but require extensive feedwater pretreatment and have a high fouling potential. Tubular membrane modules have beneficial fouling properties, can be backflushed, but have low packing densities and are expensive. Both module types exist for the nanofiltration process.

How to Optimize Hollow‐Fiber Submerged Membrane Bioreactors
Water Environment Research, 2012Membrane fouling is linked to reversible or irreversible accumulation of macromolecules and solids on membrane surfaces and to the irreversible adsorption inside pores. If reversible accumulation can be controlled by filtering in subcritical conditions, then adsorption could also be minimized by reducing the soluble organic matter [extracellular ...

Hollow-Fiber Reverse Osmosis Membranes
1972Hollow-fiber membranes for reverse osmosis desalination are typically of the dense wall type and exhibit water flux rates in the range of 0.1–1 gallons/square foot-day (gfd) [1,2]. These low flux rates are overcome by making the fibers extremely small (50 microns) in order to develop a relatively compact desalination system.
