Gas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane
In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...
متن کاملCO2 Capture by Dual Hollow Fiber Membrane Systems
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...
متن کاملHollow Fiber Membrane Bioreactor for COD Biodegradation of Tapioca Wastewater
The present work studied the application of membrane bioreactor (MBR) for tapioca wastewater processing that contained chemical oxygen demand (COD) ranging from 4000-9000 mg/L. A preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with MLSS concentration ranging from 4,500 to 10,500 mg/L. It was clear that fouling was observed during the ...
متن کاملMunicipal Wastewater Treatment Using a Hollow Fiber Membrane Bioreactor
A bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. Removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was investigated. The experimental setup consisted of influent and effluent tanks, and membrane modules using Polyvinyl Di–Fluoride (PVDF) hollow fibers. The operation program included suction and backwash...
متن کاملHollow fiber membrane adsorber: Mathematical model
Two opposite design strategies for ultrafiltration/microfiltration filters, (1) reduction of concentration polarization and particle deposition to increase permeate velocity and (2) utilization of particle deposition on membrane surface to produce an additional (to permeate) volume of clarified water, are analyzed. It is shown that the first strategy is always associated with additional expendi...
