The nanofiltration of dairy ultrafiltration permeate can be used to produce a concentrated lactose product that is reduced in unwanted monovalent salts. In this paper, the surface charge of three nanofiltration membranes commonly used for such a purp

Colloidal extractives particles are potential foulants in pulp and paper mill applications. Characterization of them as foulants is a challenging task because of the complexity of these mill waters. In this study one regenerated cellulose (RC) membra

Issues of fouling and effective cleaning limit the adoption of UF in pulp and paper mill applications. The choice of an optimal membrane for a specific filtration application is a challenging task due to the fact that fouling is a complex phenomenon.

The retention of single (NaCl) and mixed (Na2SO4 + NaCl) salt solutions by nanofiltration membranes was analysed using principal component analysis (PCA). Seven variables—five different membranes (Desal-5DK, NF 270, NF Filmtec, NF 20 and ESNA-1-LF)

It is over a decade since the concept of critical fl ux was introduced. From that time intensive research has been done to fi nd the functionality and dependency of critical fl ux for different feeds and membranes. The studies focussed on critical fl

Ultrafiltration membranes of different hydrophobicities and different pore sizes were compared in the enrichment of α-lactalbumin (aLa) to the permeate from diluted whey solutions. The experiments were performed at low transmembrane pressures (TMPs)

Dairy ultrafiltration permeate (UFP) has been filtered using polyamide nanofiltration (NF) membranes in order to separate potentially valuable calcium and lactose from unwanted monovalent salts. An investigation into both the fouling and separation b

The effects of different operating conditions on ultrafiltration (regenerated cellulose with a cut-off of 100 kg/mol) of cutting oil were studied for two different cases. The factors, examined at three levels, included: pH, oil concentration, feed fl
