“…However, more detailed study with long-time multiple filtration cycles should be carried out to confirm this statement. Tung, Li, Wang et al (2010) have demonstrated that washing PES membrane by flushing with water was not good enough to clean the membrane and restored the filtration flux. It was found that membrane flushing with caustic soda was a favorable cleaning treatment to ensure many cycles filtration without significant reduction of the permeate flux.…”

“…Hence, everywhere and anywhere filtration or clarification is required, as membrane microfiltration has the potential to replace conventional flotation, sedimentation, and media filtration processes [5]. Microfiltration (MF) is based on the size exclusion principle with particles in the range of 5 -10 m and thus allowing other smaller impurities to pass through as seen in Table 1 [6]. Over time, MF has been popular for the removal of other water impurities and has been extensively used for enhancing the removal of natural and synthetic organic matter.…”

Microporous polymeric membranes have found great applications in the area of water desalination and wastewater treatment, tissue engineering, drug delivery, and bone regeneration. The ability to create micro-size pores within a polymeric membrane allows for cavity formation that could form channels through which substances may permeate or percolate easily. The majority of these applications though, require micro-size porous membranes with small pore size and narrow pore-size distribution as to allow the control of the permeating substances or tissues. In the current work, an intricate and precise method was developed to generate micro-size porogen salt crystals with controlled micro-size distribution, which is then mixed with a specific biodegradable polymeric blend designed to offer both toughness and high flexibility for the production of microfiltration biodegradable membranes that can withstand the high pressures of large volumes of industrial wastewater undergoing filtration treatment. After casting, the porogen crystals are washed away rendering membranes with well-distributed micro-scale cavities. Using salt porogens offers a great advantage of no contamination to the environment since all salt particles are simply washed away. The ingenuity of this technique is that it allows the filtration of the wastewater at low or no pressures.

“…Alternatively, attempts have been made to apply the Kozeny-Carman equation to analyze the behavior of membrane pore blocking [10,12]. In particular, the initial stage of filtration exhibits intricate membrane-blocking behavior, and numerous researchers have reported that the influences of membrane morphology, structure, and surface properties are significant based on the abovementioned model analysis [13][14][15][16][17][18][19][20][21][22][23][24]. Ho and Zydney [13] experimentally evaluated the microfiltration of bovine serum albumin solutions using different track-etched, isotropic, and asymmetric membranes.…”

Microfiltration plays an increasingly important role in various fields. Consequently, elucidating the mechanism of membrane fouling has emerged as a pivotal issue that needs to be resolved. In this study, a blocking filtration model was employed to evaluate the effects of membrane properties on the fouling mechanism during the microfiltration of representative polysaccharides, namely sodium alginate, pectin, and xanthan gum. Microfiltration membranes composed of hydrophilic and hydrophobic PVDF, mixed cellulose ester, as well as hydrophilic and hydrophobic PTFE were used as filter media. The flux decline behavior was significantly affected by the membrane properties, with hydrophilic membranes exhibiting a slower decrease in filtration rate. The model analysis revealed a correlation between the blocking characteristic values and the membrane properties. Although the blocking index n showed membrane material dependence, the values of this parameter remained consistent across various filtration conditions, including the wettability of the membrane surface, solute concentration, and pressure (pectin: n = 1.86, 1.85, 1.50, and 1.50 for hydrophilic PVDF, hydrophobic PVDF, hydrophilic PTFE, and hydrophobic PTFE, respectively). The resistance coefficient k was influenced by the characteristics of the membrane surface; the k values of the hydrophobic membranes were higher than those of the hydrophilic ones (pectin: k = 0.00084, 0.00725, 0.00714, and 0.0384 s1−n/cm2−n for hydrophilic PVDF, hydrophobic PVDF, hydrophilic PTFE, and hydrophobic PTFE, respectively). The model calculations, based on the values of n and k, demonstrated a relatively good agreement with the experimental data.
