“…The concentration polarization resistance increased with increase in the transmembrane pressure; lower transmembrane pressures raised cake and internal plugging resistances. Li et al (2007) also showed that increasing the cross-flow velocity can decrease concentration polarization resistance; however, cake resistance reduced only after initially increasing with increased velocity. Vladisavljević et al (2003) evaluated the fouling resistance during ultrafiltration of depectinized apple juice using ceramic membranes.…”

“…The results were the same: both reversible and irreversible fouling resistances were decreased; however, the cake resistance was increased by 72% when the volumetric flow rate was increased from 10 to 20 ml/s. This is caused by the two different effects of velocity on filtration described by Li et al (2007):…”

“…Li et al (2007) analyzed the fouling resistances during microfiltration of raw soy sauce using a ceramic membrane. They concluded that total fouling resistance increased with increase in the nominal pore size due to increasing the concentration polarization resistance which happens when convective flow of compounds to membrane surface is greater than back-diffusive flow to bulk solution.…”

This study evaluated the total (R t ), reversible (R rev ), irreversible (R irr ), and cake (R c ) resistances during microfiltration of watermelon juice (as a juice with colloid particles) and red plum juice (as a juice without colloid particles). Results showed that the total resistance decreased by about 45% when the feed velocity was increased during clarification of red plum juice due to change in cake resistance. Also, increasing the feed temperature from 20 to 30°C decreased the total fouling resistance by about 9% due to decreases in the irreversible and reversible fouling resistances. Also, mixed cellulose ester (MCE) membrane (which is hydrophilic) had a lower cake resistance compared to polyvinylidene fluoride (PVDF) membrane (which is hydrophobic). Examination of the microfiltration of watermelon juice showed that R t decreased by about 54% when the feed temperature was increased from 20 to 50°C, partially due to the reduction of reversible fouling resistance by 78%. Also, increasing transmembrane pressures from 0.5 to 2.5 bars greatly increased total fouling resistance. The feed velocity had a different effect on fouling resistances during microfiltration of watermelon juice compared to red plum juice: in contrast with red plum juice, increasing the feed velocity for watermelon juice increased cake resistance.

“…Not only looking at the resistance of the membrane alone, but including cake/polarisation layer resistances, this model is used to estimate the influence of operation conditions on fouling phenomena (Tansel et al ., 2000;Li et al ., 2007). For this the cake resistance can be determined from the rate of flux decline due to cake build-up, and the contribution of fouling to the overall cake layer resistance can be estimated by measuring pure water flux after fouling has established (Mikulásek et al ., 2004;Rabiller-Baudry et al ., 2008).…”

The corn based dry grind process is the most widely used method in the US for fuel ethanol production. Fermentation of corn to ethanol produces whole stillage after ethanol is removed by distillation. It is centrifuged to separate thin stillage from wet grains. Thin stillage contains 5-10% solids. To concentrate solids of thin stillage, it requires evaporation of large amounts of water and maintenance of evaporators. Evaporator maintenance requires excess evaporator capacity at the facility, increasing capital expenses, requiring plant slowdowns or shut downs and results in revenue losses. Membrane filtration is one method that could lead to improved value of thin stillage and may offer an alternative to evaporation. Fractionation of thin stillage using ultrafiltration was conducted to evaluate membranes as an alternative to evaporators in the ethanol industry. Two regenerated cellulose membranes with molecular weight cut offs of 10 and 100 kDa were evaluated. Total solids (suspended and soluble) contents recovered through membrane separation process were similar to those from commercial evaporators. Permeate flux decline of thin stillage using a resistance in series model was determined. Each of the four components of total resistance was evaluated experimentally. Effects of operating variables such as transmembrane pressure and temperature on permeate flux rate and resistances were determined and optimum conditions for maximum flux rates were evaluated. Model equations were developed to evaluate the resistance components that are responsible for fouling and to predict total flux decline with respect to time. Modeling results were in agreement with experimental results (R(2) > 0.98).
