viscosity (µ) and density (ρ) are important physical roperties for analysis of membrane processes performance and for designing a new membrane process. in addition, the energy requirement for fluid pumping is depend on these two physical properties magnitiude. in this study, firstly, the effects of different process factors such as transmembrane pressure (51, 101, 152, 203 and 253 kpa), tempera...

The article deals with the study of processing quality of milk-protein concentrates obtained by ultrafiltration. Creaming ability of milk-protein concentrates obtained by ultrafiltration is inevitably associated with the presence of rehydrated proteins in its composition. With increasing temperature, the ability of proteins to absorb on the plasma-gas interface is reduced, as evidenced by a dec...

A two-step-cascade membrane separation by ultrafiltration was performed on caprine milk prepared under different temperature conditions to eliminate beta-lactoglobulin (β-Lg) from the whey fraction. Effects of temperature treatment and membrane pore size on the elimination of β-Lg and retention of alpha-lactalbumin (α-La) were examined to determine the optimum permeate fraction for production o...

a neuro-fuzzy modeling tool (anfis) has been used to dynamically model cross flow ultrafiltration of milk. it aims to predict permeate flux and total hydraulic resistance as a function of transmembrane pressure, ph, temperature, fat, molecular weight cut off, and processing time. dynamic modeling of ultrafiltration performance of colloidal systems (such as milk) is very important for designing ...

Milk ultrafiltration is a membrane process, which is highly complex innature. The cost effectiveness of the process depends heavily on the flux permeate and the total hydraulic resistance of the membrane. In this work, a comparative study for the prediction of the performance of milk ultrafiltration with ANN and statistical method has been carried out. The result reveals that both methods c...

Ultrafiltration of skim cow’s milk with a UF10-PAN membrane at volume reduction ratios (VRRs) 2 and 3 was performed. The ultrafiltration retentates obtained were used for production probiotic yoghurts three different starters. A control sample prepared using milk. All analysed according to the following parameters: titratable acidity, dry matter, organoleptic characteristics, number specific mi...

The objective of this work was to determine if concentration of milk using ultrafiltration (in the absence of diafiltration) affects the physico-chemical properties of the casein micelles. The milk, once concentrated, was brought back to its original concentration and the physico-chemical properties as well as its susceptibility to rennet induced gelation were assessed. Although much is underst...
