Effect of Elevated Temperature on Ceramic Ultrafiltration of Colloidal Suspensions

Filtration of subcritical water hydrolysates from red macroalgae byproducts with ultraporous ceramic membranes for oligosaccharide and peptide fractionation

“…The pure water permeate flux, J 0 , at TMP = 1.1 bar was 46.9 ± 0.3, 47.5 ± 0.5 and 49.3 ± 0.5 L/m 2 h using 6.6 L water/h at 20 that for SWH feed solution, the permeate flux and the mass transfer coefficient were mainly affected by temperature and, to a lesser extent, by the feed flow rate. This favourable effect of temperature on the permeate flux due to lower permeate viscosity has also been confirmed in many studies [20,[40][41][42][43][44][45], which is in accordance with the Hagen-Poisuille equation.…”

Highly alkali caustic discharges recovery using tubular and disc type of ceramic membranes and its applicability as a near zero liquid discharge opportunity in the textile industry

“…When the main fouling mechanism is examined with the "Resistance-in-Series Model" according to Section 2.5 that the effective mechanism has been the physically removable resistance (Rc), as expected (Ağtaş et al, 2020;Cromey et al, 2015;Dilaver et al, 2018;Lee and Kim, 2014).…”

“…Recovery of pure water flux after backwashing was 98% for 15 kDa+1 kDa. Similarly, in studies evaluating the fouling mechanism of ceramic membranes in the literature, it has been stated that the effective fouling mechanism is the resistance that can be physically removed and the irreversible contamination (Rif) is at a negligible level (Cromey et al, 2015;Dilaver et al, 2018;Lee and Kim, 2014;Lee et al, 2013).…”

“…Ceramic membranes are much more advantageous than polymeric counterparts due to their high thermal, chemical and mechanical resistance. In addition to the thermal and mechanical strength advantages of ceramic membranes over polymeric counterparts, the effective fouling mechanism is resistance that can be physically removed (Lee et al, 2013) (Lee and Kim, 2014) (Cromey et al, 2015). These advantages make ceramic membranes particularly suitable for the treatment of textile wastewater with high temperatures and high alkalinity (Alventosa de Lara, 2015).…”

Ceramic membrane overview and applications in textile industry: a review

“…Especially when used in hot wastewater treatment in the textile industry, ceramic membrane flux values will increase further, depending on the viscosity decreasing with increasing temperature (Dilaver et al 2018). In addition, because of the high pH and chemical resistance of the ceramic membranes, the membrane performance can be recovered more efficiently, as the membranes can withstand a more aggressive cleaning process (Cromey et al 2015). Considering the characteristics of the textile wastewater and the properties of ceramic membranes together, the use of these membranes in textile wastewater treatment is also recommended in the literature (Barredo-Damas et al 2012).…”
