Chicory juice clarification by membrane filtration using rotating disk module

Leaf protein concentration of alfalfa juice by membrane technology

“…Due to its open flow channel structure, the CRDM has a better mobility for feed flow and reduces concentration polarization. In fact, dynamic filtration systems can operate at low feed flow rates, which are just slightly greater than permeate flow rate (about 10-13% for nanofiltration and reverse osmosis and 3-5% for UF and MF) [22,24], thus they do not need powerful and large pumps as in traditional dead-end and cross-flow filtration and have lower energy consumption for feed pump. In summary, compared with other filtration modules, as shown in Fig.…”

“…As shown in Fig. 10, permeability recovery defined as the ratio of pure water flux before concentration and being fouled or after cleaning [24], is used to estimate membrane fouling and cleaning efficiency for different types of filtration modules. MF had a larger membrane fouling and lower permeability recovery than UF, because the more serious pore blocking of MF produced greater irreversible fouling.…”

“…Shearenhanced modules can create a high shear rate on the membrane surface by a moving part such as a rotating membrane, or a disk rotating near a fixed circular membrane or by vibrating the membrane either longitudinally or torsionally around a perpendicular axis, inducing dispersion of solutes on the membrane surface and elimination of membrane fouling [22]. Therefore, it outweighs the conventional cross-flow membrane filtration process in excellent effluent quality, stable permeate flux, low concentration polarization and high retention and has been successfully implemented in many fields of research and engineering such as wastewater treatment [18], medical engineering [22] and food engineering [23] as well as biotechnological separations [24].…”

Primary Clarification of Banana Juice Extract by Centrifugation and Microfiltration

“…All the parameters of the product from both the processes are comparable but since microfiltration removes all the suspended solids, it was selected as a better alternative. Crossflow microfiltration was used to clarify pineapple (11,12), melon (13), passion fruit juice (14), apple (15)(16)(17), pomegranate (18,19), bergamot (20), chicory (21,22), and acerola (23).…”

The impact of mechanical shear on membrane flux and energy demand

“…Using dynamic filtration has been shown by various investigators [4][5][6][7][8][9][10][11] to greatly suppress CP limitations, reducing the membrane area requirement [12]. The process appears especially effective for high-value, small-scale duties, including various dairy industry applications [6,[13][14][15][16][17][18][19][20][21][22][23][24][25], the treatment of yeast dispersions and bovine albumin solutions [4,5,26], pulp and paper industry applications [7,27] and specialist beverage process separations, such as the treatment of chicory juice [28][29][30] or sugar beet juice [31,32]. It has also found use in landfill leachate treatment [33,34], arsenic removal from drinking water [11,35], treatment of brine and brackish water [36][37][38], removal of natural organic matter [10,39,40], livestock wastewater treatment [8,41,…”
