“…The cake layer of FeCl 3 pretreatment was more porous while that of PFC 22 denser. This agreed with above membrane fouling results as the membrane flux can be enhanced due to a relatively looser structure of cake layer [39]. As showed in Table 2, R c relative to the R t was smallest for FeCl 3 , which was consistent with the result of SEM observation in Fig.…”

“…These macromolecules especially the polysaccharides and enzymes (proteins) caused the decrease in the permeate flow through the membrane, which can be attributed to the fouling of its surface where the nonpermeating solutes tended to form a gel layer. 17,18 The permeation characteristics of membranes not only depend on molecular weight of the solutes, but other factors such as charge and hydrophobicity will also affect the permeation of glucose. In addition, since lignocelluloses hydrolysate is a complex mixture, the presence of protein will also lead to fouling arising from specific interaction between protein and membrane.…”

“…The main drawback have been noted with the reduction of permeate flux over time in ultrafiltration, caused by the accumulation of feed component in the membrane porous structure, chemical interaction between solutes and membrane materials on the membrane surface. These macromolecules especially the polysaccharides caused the decrease in the permeate flow through the membrane which can be attributed to the fouling of its surface where the non-permeating solutes tending to form a gel layer [9,10].…”

Concentrating glucose after enzymatic hydrolysis of lignocellulosic biomass is an important step in order to prepare the stream to undergo the fermentation process. However, glucose itself can be inhibitor for the enzymatic hydrolysis, hence in situ glucose removal is recommended. Ultrafiltration represents a promising procedure for isolation of enzymes from hydrolysate and for the removal of glucose. One of the obstacles in successfully utilizing ultrafiltration's membranes has been due to the membrane fouling. The flux behavior of polysulfone (PSF) membrane was studied in concentrating glucose from cellulose hydrolysate during dead end ultrafiltration. Different pH of solutions was used and Kumar's model was applied to analyse the fouling mechanism. The minimum fouling was obtained at pH solution above the IEP due to protein-protein and membrane-protein repulsions alleviating aggregation and fouling. Cake formation blocking was identified as the dominant mechanism for flux decline.Keywords: enzyme hydrolysis, lignocellulosic biomass, ultrafiltration, polysulfone, fouling Abstrak Pemekatan glukosa selepas hidrolisis enzim bagi penghasilan bioetanol daripada biojisim lignoselulosa merupakan langkah yang penting bagi penyediaan untuk proses fermentasi selanjutnya. Penuras ultra menjadi pilihan bagi kaedah yang berpotensi untuk penyekatan enzim dan penyingkiran glukosa daripada larutan hidrolisis. Namun, salah satu rintangan bagi penggunaan maksima bagi penuras ultra adalah kotoran. Kriteria fluks bagi membran polisulfon di kaji dari pemekatan glukosa oleh larutan hidrolisis selulosa di penuras ultra hujung mati. Larutan yang berlainan pH digunakan untuk mengkaji profil fluks dan model Kumar digunakan untuk menganalisis mekanisma kotoran. Kotoran yang minima diperolehi pada larutan yang mempunyai pH yang lebih tinggi daripada nilai titik isoelektrik larutan hidrolisis. Halangan pembentukan kek telah dikenalpasti sebagai mekanisma yang dominan bagi pengurangan fluks.
