“…We devised the analysis model called a frictionconcentration-polarization model (FCP model) for the SOE structure hollow fiber module by previous study and reported it in detail. [12][13][14][15] Performance analysis of the BOE element was conducted by using this analysis method of SOE element as a base. Since the details of the FCP model were already reported, an outline is shown below.…”

The use of seawater desalination plants using RO technology has spread and the scale of the plants has increased. In such a situation, a larger-sized RO module has been strongly required. The conventional hollow fiber type RO element is a single open-ended (SOE) structure. That is, one side of the hollow fibers in the modules is opened and the other side is closed. In this SOE structure, the increase in the flow pressure loss of the permeated water which flows in the bore side of the hollow fibers prevents development of a large-sized (longer) RO element. In this work, a both open-ended (BOE) element was devised which can reduce the flow pressure loss of the permeated water. It has been confirmed by analysis and experiment that the permeate flow rate of BOE is greater by about 30% than that of SOE. Furthermore, the large-sized RO module with high volume efficiency was designed using the performance analysis method that was confirmed to be applicable to BOE.

“…This model, designed originally to explain the transport of gases through polymeric films, has been adapted for membrane separation processes and is used in modeling of such techniques as reverse osmosis [7,8], nanofiltration [9,10], gas separation [11,12] and pervaporation [13,14].…”

A B S T R A C TThe aim of this study was a mathematical description of the kinetics of ethanol separation from fermentation broth of Saccharomyces cerevisiae yeast by the vacuum pervaporation technique. Model equations were developed on basis of the solution-diffusion theory. The finite differences method has been used to calculate the concentration profiles of permeants within the membrane. The optimal number of grid points and their distances were found by numerical tests. The formulated model describes the transport of feed components under the non-stationary conditions. Model equations were solved with the use of the backward differentiation method. Model parameters were estimated by fitting of experimental data with the use of the Nelder-Mead method. Calculations were performed for separation experiments with broths containing 3-6 wt% of ethanol. Very good agreement with the experimental data was obtained.
