Did you know?
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 1960s for reverse osmosis applications, hollow fiber membranes have since become prevalent in water treatment, desalination, cell culture, medicine, … Se mer HFMs are commonly produced using artificial polymers. The specific production methods involved are heavily dependent on the type of polymer used as well as its molecular weight. HFM production, commonly referred to … Se mer The properties of HFMs can be characterized using the same techniques commonly used for other types of membranes. The primary properties of interest for HFMs are average pore diameter and pore distribution, measurable via a … Se mer • Membrane • List of synthetic polymers • Reverse Osmosis • Nanofiltration Se mer Hollow fiber membranes are ubiquitously used in industrial separations, especially the filtration of drinking water. Industrial water filters are mainly equipped with ultrafiltration hollow filer membranes. Domestic water filtration systems have microfiltration hollow … Se mer NettetMeanwhile, we summarize four types of hollow fibers: one-layered hollow fibers, multi-layered hollow fibers, multi-hollow fibers and branched hollow fibers. Next, we focus on the main applications of hollow fibers, such as gas separation, cell culture, microfluidic channels, artificial tubular tissues, etc.
NettetIn the hollow fiber membrane system, the fibers are commonly characterized with inner radius, fiber length, and membrane resistance. The operating parameter is the transmembrane pressure at the open-end of the fiber ∆P. The overall permeate production rate is a more important concern for hollow fiber membrane system. Therefore, Nettet1. jul. 2009 · Using hollow fiber gas-liquid membrane contactors is a promising alternative to conventional gas absorption systems for acid gas capture from gas …

After the first cycle, the results showed that the shape fixity ratio ( Rf) with 13% and 33% hollowness were between 80% and 84%. When the hollow degree of the fiber was 0%, the Rf was more than 88% and the shape recovery ratio ( Rr) was 59%.
NettetHollow fiber is one of the most popular membranes used in industry. The hollow fiber usually has a membrane coated on the outside of a porous fiber support as shown in Fig. 4.9. Hollow fiber modules are characteristically 4–8 in. (10–20 cm) in diameter and 3–5 ft (1.0–1.6 m) long. The membrane is often applied to the outside fiber by a ...
