Effective Parameters on Fabrication and Modification of Braid Hollow Fiber Membranes: A Review

Abstract: Hollow fiber membranes (HFMs) possess desired properties such as high surface area, desirable filtration efficiency, high packing density relative to other configurations. Nevertheless, they are often possible to break or damage during the high-pressure cleaning and aeration process. Recently, using the braid reinforcing as support is recommended to improve the mechanical strength of HFMs. The braid hollow fiber membrane (BHFM) is capable apply under higher pressure conditions. This review investigates the fab… Show more

“…We then strived to fabricate the UF PES substrate, with the goal to optimize the membrane structure so it withstands the lasing while keeping the structural integrity of the LIG UF membrane. Among various fabrication parameters, polymer concentration has been identified as the most important parameter to tailor the membrane properties . Higher polymer concentration results in the fabrication of a denser and thicker skin layer but lower permeability .…”

“…Polymer concentration together with the solvent ratio is the most significant parameter that directly affects membrane properties. Increasing concentration leads to an increase in dope solution viscosity, dense skin layer becomes thicker, and reduction in macro voids, [1] as well as transferring membrane structure from finger-like to sponge-like [7]. On the other hand, adding a specific amount of non-solvent (water, ethanol, acetone) to the polymer solution well provides a good membrane porous structure [13][14][15][16].…”

“…1. Membrane classification according to structure morphology [4] Hollow fiber ultrafiltration membrane was first stated in1966, this type of membrane is not suitable for RO or NF process which applied high pressure because of poor mechanical properties [7], however, it is one of the most interesting membranes modules as it has many advantages among other modules such as high productivity per unit volume [8], self-supporting and easy operation [4].…”

“…It has some advantages like high-mechanical endurance, good durability to moderate chlorine, and caustic. 25 In this research, braid reinforced hollow fiber membranes are produced by applying polysulfone polymer (PSf) and polyvinylpyrrolidone (PVP) additive as poreformers. The primary scope of the research is to understand the PVP effect on the braid reinforced hollow fiber membrane performance and also, braid reinforced hollow fiber membranes can be utilized as support layers for thin-film composite membranes by applying different concentrations of PVP.…”
