“…Experiments with polymeric and ceramic membranes of pore size 0.54/0.87 and 1.0 m, respectively, were reported by Guerra et al [8]; no protein retention was observed, and a trans-membrane pressure was found above which flux decreased with increasing pressure. Tubular ceramic membranes, of relatively small pore size, were used in studies dealing with the prediction of limiting flux [9] and whey protein cross-flow microfiltration was the subject of recently published work on the effect of critical flux on fouling [10,11]. The reduction of spores and bacteria in milk, utilizing crossflow microfiltration and ceramic membranes has been an early research objective [12,13].…”

“…Regarding ceramic membranes, there is already evidence in the literature [8] that the main targets (i.e. very high microbial, and very low protein, rejection) can be achieved with nominal pore sizes near 1.0 m, whereas protein retention and fouling tend to be significant [9,10] in the pore size range 0.1-0.2 m, unless one wishes to employ high crossflow velocities, e.g. 5-7 m/s.…”

“…Belfort et al (3)(4)(5) have summarized the behavior of suspended particles during microfiltration. Other researchers have studied the behavior of macromolecules during microfiltration (6)(7)(8)(9). Only a few studies have been reported in the literature on modeling the behavior of poly-disperse feeds containing both macromolecules and suspended particles for microfiltration (10,11).…”

A methodology, called the aggregate transport model, is presented that can a priori predict both the pressure-independent permeation flux and yield of target species for the microfiltration of poly-disperse solutions. The model captures the phenomenon of critical shear rate. Beyond the critical shear rate (expressed as a ratio of shear rate to permeation flux), the transmission of proteins drops sharply as a result of cake classification. The widely reported benefits of operating at uniform transmembrane pressure and constant wall concentration follow from this method. The methodology is general in nature and can be used predictively to obtain an optimal balance between flux and yield of target species during the microfiltration of many commercial poly-disperse suspensions. In the accompanying paper we test this model for microfiltration of transgenic whole goat milk.

“…These approaches are based on some models such as mass transfer model (Bhattacharjee and Datta 1997;Lin and Juang 2001), gel-polarization model (Palacios et al 2002), osmotic pressure model (Wijmans et al 1984;Ghose et al 2000), Brownian diffusion model (Samuelsson et al 1997), and shear-induced diffusion model (Kromkamp et al 2002;Vincent Vela et al 2007). The complexity of these mathematical models and their nonuniversality would limit their application.…”

In this study, a hydrophilic polyethersulfone membrane was used to modify the expensive and low efficient conventional treatment method of wheat starch production that would result in a cleaner starch production process. To achieve a cleaner production, the efficiency of starch production was enhanced and the organic loading rate of wastewater that was discharged into treatment system was decreased, simultaneously. To investigate the membrane performance, the dependency of rejection factor and permeate flux on operative parameters such as temperature, flow rate, concentration, and pH of feed were studied. Response surface methodology (RSM) has been applied to arrange the experimental layout which reduced the number of experiments and also the interactions between the parameters were considered. The maximum achieved rejection factor and permeate flux were 97.5% and 2.42 L min -1 m -2 , respectively. Furthermore, a fuzzy inference system was selected to model the nonlinear relations between input and output variable which cannot easily explained by physical models. The best agreement between the experimental and predicted data for permeate flux was denoted by correlation coefficient index (R 2 ) of 0.9752 and mean square error (MSE) of 0.0072 where defuzzification operator was center of rotation (centroid). Similarly, the maximum R 2 for rejection factor was 0.9711 where the defuzzification operator was mean of maxima (mom).
