In this study, a membrane separation module for the dialysis of beer has been taken as an example system to illustrate the multi-objective optimization of any membrane module.
We report irreproducibility analysis of miniaturized, batch, continuous stirred-tank Donnan dialyzers (CSDD) designed for a membrane-separation module of chemical analysis systems.
In order to address the irreproducibility issue, we introduce a novel, microfluidic, parallel-plate Donnan-dialytic membrane-separation module (PDMM) with recirculation tube.
Fuzzy logic-based (FL) model and Principal Component Analysis (PCA) were employed to predict permeability of C3H8, CH4 and H2 in ternary gas mixtures using a membrane gas separation module.
For several membrane separation processes, hollow fibre modules are either an already established or a promising type of module.
As most of the industrial membrane separation units use hollow fiber modules, having a proper model for simulating this type of membrane module is very useful in achieving guidelines for design and characterization of membrane separation units.
The results indicated that sparging the bioreactor with the CO2-concentrated fraction of the membrane separation unit (consisting of two PDMS modules) enhanced the steady-state H2 productivity (8.9 9.2 L H2/L-d) compared to the membrane-less control CSTR to be characterized with 6.96 7.35 L values values.
Fluid hydrodynamics within these modules is as important as intrinsic membrane separation properties.
After a preliminary assessment, the membrane separation section is selected and designed on several membrane modules in series with adiabatic high temperature shift in between.
This new design is flexible, compact, eco-friendly, and modular and, operated in a cross flow module that ensures almost fouling-free membrane separation while overcoming the product inhibition of traditional batch fermenters.
