“…Conventionally, the experimental data of the flux decline during the blocking filtration period have been analyzed by only one of above mentioned blocking filtration laws (Granger et al, 1985;Hodgson et al, 1993;Blanpain et al, 1993;Ruohomäki and Nyström, 2000;Gironès et al, 2006;Lee et al, 2008;de Lara and Benavente, 2009;Nandi et al, 2010;Li et al, 2012;Lim and Mohammad, 2012;Pan et al, 2012;Masoudnia et al, 2013, Palencia et al, 2014.

Blocking filtration laws consist of four different filtration mechanisms: complete blocking, standard blocking, intermediate blocking, and cake filtration. Blocking filtration laws for describing both the pore blocking and cake formation have been extensively employed over the past several decades to evaluate the increase in filtration resistance with the progress of filtration in the field of classical particulate filtration. In recent years, blocking filtration laws become widely used also in membrane filtration such as microfiltration and ultrafiltration of colloids. This paper gives an overview of the developments of blocking filtration laws and equations under constant pressure and constant rate conditions reported for the filtrate flow of Newtonian and non-Newtonian fluids. The fouling index evaluating the degree of membrane fouling was examined on the basis of the blocking filtration equations. The blocking filtration laws were reexamined to extend the range of their application. Moreover, various combined models developed based on the blocking filtration laws were introduced for describing more rigorously the complicated filtration behaviors controlled by more than one mechanism which occurs successively or simultaneously.

“…Whey protein desorption experiments were carried out both in static conditions (without any applied TMP across the membrane) and in dynamic ones (with an applied TMP at constant permeation rate). A 1 wt% sodium dodecyl sulphate (SDS) solution, an anionic surfactant of critical micellar concentration ≈8.3 mM at 25 • C (SDS purity of 99%, Sigma-Aldrich, France), was used as SDS was shown to be efficient in solubilizing adsorbed proteins [98][99][100]. Static method desorbs primarily the proteins deposited on the selective layer of the membrane (external proteins).…”

“…A solvent stripping method, i.e., the determination of desorbed proteins [97], was selected to evaluate the amount of residual proteins adsorbed or deposited on the membrane surface after the cleaning-rinse operation. Such a method, consisting of the removal of proteins by a surfactant, proved to be useful and convenient to determine small amounts of adsorbed proteins (equivalent to a few micrograms per unit membrane surface area) on MF/UF organic membranes [98][99][100]. Whey protein desorption experiments were carried out both in static conditions (without any applied TMP across the membrane) and in dynamic ones (with an applied TMP at constant permeation rate).…”

The transmission and rate of filtration of the enzyme yeast alcohol dehydrogenase (YADH) has been studied at capillary pore microfiltration membranes. Photon correlation spectroscopy (PCS) with nanometer resolution showed that the enzyme existed as discreate molecules only for a narrow range of pH and ionic strength. Under such conditions, the transmission of the enzyme was high. However, the rate of filtration still decreased continuously with time. Analyssis of the time dependence of the rate of filtration indicated that this decrease was due to in-pore enzyme deposition at low concentration ("standard blocking model") and suface depositon at high concentration ("cake filtration model"). Use of atomic force microscopy (AFM) gave unequivocal and quantitative confirmation of these inferences. The work shows the great advantage of using advanced physical characterization techniques, both for the identification of the optimum conditions for filtration (PCS) and for the elucidation of mechanisms giving rise to inefficiencies in the filtration process (AFM).
