Hollow Fibre Ultrafiltration of Apple Juice: Macroscopic Approach

“…Table 4 also shows values of the parameters of Eqn [5] for different operating conditions. Energy consumption during hollow fibre ultrafiltration of apple juice under different operating conditions was calculated from Eqn [2] using average values of J and ∆P TM in the range VCR = 1 to 10. Results obtained are listed in Table 6.…”

“…VCR is defined as the initial volume divided by retentate volume at any time. Other authors explain the fouling in tangential UF and microfiltration (2,3) by application of the classical laws of filtration through a cake at constant pressure. In a previous work (4) the stationary permeate flux of apple juice through a hollow fibre membrane (HFUF) module was studied.…”

“…It is well known (Iritani et al, 1991) that the transmembrane pressure-permeate flux characteristic for ultrafiltration shows a linear dependence of J with DPTM at lower values of pressure (1st region), while the permeate flux approaches a limiting value (J lim ) independent of further increase in pressure at higher pressures (2nd region). The last situation was assumed to be controlled by mass transfer.…”
