“…Furthermore, Figure 10(b) shows that the flexural stress values of the tubes treated at 25°C, 550°C, 750°C, 950°C and 1150°C are 1.1 ± 0.1, 2.6 ± 0.3, 4.3 ± 0.6, 7.8 ± 0.8 and 15.7 ± 0.9 MPa, respectively. Accordingly, the mechanical strength of the support membrane improved significantly with the increase in the treating temperature, and consequently the mechanical strength relating to 1150°C was considerably higher than others, even higher than other porous ceramics with similar porosities reported in the literature [20]. This finding most likely results from phase transformation as explained previously (see section 3.2).…”

“…In confirmation, Arzani et al [20] showed that with the increase in the porosity and pore size of the ceramic membrane structure, its mechanical strength was weakened. Besides, Terpstra et al [36] demonstrated that the finger-like structure could be considered as a defect formed by the agglomeration of ceramic particles and lack of de-airing, which lowered the mechanical strength as a consequence.…”

“…Figure 11 highlights the other polymeric materials. Besides polymers, several non-organic materials were identified, either as monolithic membranes [33] or mixed matrix membranes (MMM), with ceramic nanoparticles embedded within a polymer matrix [32]. SiO2 (8.7%) and Al2O3 (7.8%) were the main non-organic MF membrane materials with the others shown in Figure 11.…”

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.

“…Dar estructura y forma cristalina bien definida a los materiales porosos se lleva a cabo con la adición de compuestos inorgánicos con fases cristalográficas estables [16][17][18]. Por tal razón, en la síntesis del material se adiciona carbonato de calcio (CaCO3), uno de los minerales más abundantes en la corteza terrestre producido por organismos vivos a través del proceso conocido como biomineralización [19].…”

The present work reports the microstructure, physical and mechanical properties of a material composed of kaolin, diatomite and calcium carbonate reinforcement (CaCO3). The ceramic prototypes were shaped by the slip casting method and sintered at temperatures between 800 °C and 1100 °C. The morphology and average pore size was analyzed by Scanning Electron Microscopy (SEM) and the mineralogical phases were determined by X-Ray Diffraction (XRD). The apparent density was established by the mercury immersion method according to the E – 8B Standard of the Institute of Ceramic Technology (ITC); the percentage of absorption was determined by the boiling method according to ISO 10545-3 standard; linear contraction was studied in three directions: long, wide and high. The study of the mechanical resistance to compression followed the procedure established at ASTM C773–88 standard and the breaking modulus was calculated by the three-point bending test, according to ISO 10545–4. Results show that the material structure is affected with increasing temperature reporting a decrease in quartz phase from 51.16 % to 33.81 %. Percentage of absorption revealed its most significant variation between 950 °C and 1100 °C with a decrease of 21 % approximately. Mechanical resistance values showed wide dispersion which was attributed to the different orientations in which the material failed during each test. According to the pore diameters found, the compound is characterized by being macro and mesoporous facilitating its application in catalysis, photochemistry, microelectronics and other microfiltration media
