Clarification of technical sugar solutions through a dynamic membrane formed on a porous ceramic tube

Quality and filtration characteristics of sugar beet juice obtained by “cold” extraction assisted by pulsed electric field

“…Consequently, it requires a number of additional unit operations (preliming, liming, 1st and 2nd carbonation, several filtrations, and sulfitation). The cross-flow microfiltration of juice extracted by hot water was proposed in order to avoid or to decrease the use of lime and multiple purification steps (Kishihara et al, 1989;Vern et al, 1995;Cartier et al, 1997;Decloux et al, 2000;Hinkova et al, 2002;Ghosh and Balakrishnan, 2003;Hakimzadeh et al, 2006;Jegatheesan et al, 2009). However, low purity of the thermally extracted juice decreases filtrate quality and results in quick membrane fouling (Hatziantoniou and Howell, 2002;Saha et al, 2006).…”

Resistance in series model for ultrafiltration of mosambi (Citrus sinensis (L.) Osbeck) juice in a stirred continuous mode

“…All of them can be classified in three broad categories, namely (a) osmotic pressure controlled, (b) gel layer controlled and (c) resistance in series models. According to resistance in series model, the flux decline is due to the combined effects of irreversible membrane fouling [1] and reversible fouling (concentration polarization) over the membrane surface [2,3] in addition to the membrane resistance. In gel polarization model, the major resistance offered to solvent flux is resistance of the gel layer over the membrane surface [4,5].…”

Resistance in series model for micellar enhanced ultrafiltration of eosin dye

“…All of them can be classified into three broad categories: (a) osmotic-pressure-controlled models, (b) gel polarization models, and (c) resistance-in-series models. According to resistance-in-series models, the flux decline is due to the combined effects of (i) fouling of the membrane (reversible and/or irreversible pore blocking) [15,16] and (ii) concentration polarization over the membrane surface [17][18][19]. But in gel polarization models the decrease in flux is due to the hydraulic resistance of the deposited gel layer over the membrane surface [20,21].…”
