“…Several MF membrane materials were identified during the course of 10 years. Similar to NF and RO membranes, MF membranes may also be fabricated in several layers with and without fillers, consisting of active and support layers forming the membrane structure [31]. Figure 11 shows the most common organic and non-organic materials identified in this review for MF membrane fabrication and modification in terms of percentage, while Other most common MF membrane materials found in this literature review included PES (10.4%), CA (7.7%), PP (7.2%), PSf (7.1%) and PA (6.1%).…”

Since its inception in the 19 th century, microfiltration (MF) has evolved as a membrane-based separation technology for treating various effluents and wastewaters. This review aims to familiarize its readers with general and specific research trends on various topics in MF. The level of research interest has been measured by the number of publications in that area for each year. An increasing research trend was observed from the number of publications since 2009 to 2018 with MF as the major topic. During the past decade, MF articles have spanned in about 150 different journals, with The Journal of Membrane Science, Desalination and Separation and Purification Technology being the major ones. Major topics of interest include membrane fabrication and modification, waste water treatment and fouling studies, while a significant research increase was seen in various fabrication methods and MF application in the food sector. MF modeling still remains a topic which needs further research output, and has experienced a decline over the past years. Several potential research areas are also identified in this review which will help future researchers to materialize their efforts into the right direction.

“…Porous ceramic materials have been used in the fields of thermal insulators [ 1 , 2 ], adsorbents [ 3 , 4 ], catalyst supports [ 5 , 6 ], electrodes in solid oxide fuel cells [ 7 , 8 ], or filtration membranes [ 9 , 10 ]. Its pore structure significantly affects the mechanical properties and the strength of porous ceramics decreases exponentially with increasing porosity [ 11 ].…”

The Effect of Particle Shape on Sintering Behavior and Compressive Strength of Porous Alumina

Alumina particles with different shapes, such as sphere, rod, and disk, were examined for the sintering behavior and compressive strength of partially sintered porous alumina. While both the spherical and disk-like particles were packed well to the relative density of 61.2–62.3%, the packing density of rod-like particles was only 33.5%. The sintering rate of alumina particles increased in the order of disk < rod < sphere. The compressive strength of sintered porous alumina was higher for the spherical particles than for the rod-like and disk-like particles. The uniform distribution of the applied load over many developed grain boundaries contributed to the increase in the compressive strength for the spherical particles. The applied load concentrated on a few grain boundaries of rod-like or disk-like particles, caused fracture at a low compressive stress.

“…The multichannel flat clay‐bonded SiC membrane (20 mm length, 50 mm width, 4 mm thick containing 16 inner channels) with 44% porosity, 3.3 µm pore diameter, and flexural strength 32.7 MPa reported to exhibit pure water permeability of 25 000 Lm −2 h −1 bar −1 continuously for 5 hours . The membrane consisting of clay‐bonded SiC support with SiC‐based filtration layer sintered at 1100°C with an average pore size 93 nm showed pure‐water permeability of 210 Lm −2 h −1 bar −1 and reported to exhibit very stable permeance over a long period of time . The dead‐end filtration system with pore size 250 nm showed pure‐water permeability 240 Lm −2 h −1 bar −1 .…”

Porous SiC ceramic is considered as a suitable material for hot gas filtration, microfiltration, and many others industrial applications. However, full utilizations of porous SiC ceramics have been limited by high‐processing costs. In this study, mullite‐bonded porous SiC ceramics membranes were prepared using commercial SiC powder, alumina, clay, and different sacrificial pore formers. The effect of different pore formers on the microstructure, mechanical strength, porosity and pore size distribution, air, and water permeability of porous SiC ceramics were investigated. The average pore diameter, porosities, and flexural strength of the final ceramics varied in the range 3.7‐6.5 µm, 38‐50 vol. %, and 28‐38 MPa, respectively, depending on the characteristics of pore former. The Darcian (k1) and non‐Darcian (k2) permeability evaluated from air permeation behavior at room temperature was found to vary from 1.48 × 10−13 to 4.64 × 10−13 m2 and 1.46 × 10−8 to 6.51 × 10−8 m, respectively. All membranes showed high oil rejection rate (89%‐93%) from feed wastewater with oil concentration of 1557 mg/L. The membrane with porosity ~48 vol% and mechanical strength 31.5 MPa showed and highest pure water permeability of 13 298 Lm−2h−1bar−1.
