The mathematical equation for Separation of the binary aqueous solution is developed by using the SpieglerKedem theory. The characteristics of a B-9 hollow fibre module of Du Pont are determined by using these equations and their results are compared with the experimental results of Ohya et al. The agreement between these results is found to be excellent. Keywords—Binary aqueous solution, model...

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...

Ring-structured Bragg fibres that support a single TE-polarisation mode are investigated. The fibre designs consist of a hollow core and rings of holes concentric with the core, which form the low-index layers of the Bragg reflector in the cladding. The effects of varying the air fraction in each ring of holes on the transmission properties of the fibres are analysed and an approximate model ba...

Windmill palm (Trachycarpus fortunei) fibre was obtained from different parts of windmill-palm trunk sheath and then treated by sodium hydroxide solution and hydrogen peroxide to obtain the treated palm fibril. The appearance of raw windmill palm fibre and treated palm fibril, morphological characteristics, and statistical analysis of fibril length, diameter, and degree of hollowness were studi...

A membrane biofilter is used to biodegrade toluene in the gas phase. Active microorganisms are immobilized on the outside of a hollow fiber membrane cartridge and air containing toluene as the contaminant is passed through the membrane fibers. A porous polysulfone membrane containing water in the pore is used through which both toluene and oxygen are diffused to the biofilm attached to the outs...

Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can no longer meet requirements in terms of volume or quality, or the membrane simply breaks up (hollow fibers), and the system has to be shut dow...

Haematopoietic stem cells (HSCs) Mesenchymal stem cells (MSCs) Induced pluripotent stem cells (iPSCs) Bioprocess modelling Hollow fibre bioreactors In order to meet the expanding market for stem cells in both clinical and drug discovery applications, automated, cost-effective, large-scale manufacturing processes are required to overcome the technical and commercial challenges posed by tradition...
