“…However, they have a high manufacturing cost, mainly due to the materials that are synthetic, so that they are limited for large-scale applications, thus demanding the research and development of sources of economically viable raw materials [10][11] . Recent studies point to the phase of mullite ceramics as a good alternative in order to reduce the cost of manufacturing, since it can be obtained by economically viable sources and presents properties that ensure good performance in the preparation of ceramic membranes [10][11][12][13][14][15] .…”

The development of ceramic membranes with different geometries and compositions extends the possibilities of industrial applications, inducing advantages in terms of increased permeability, membrane area by volume module and chemical, thermal and mechanical resistance. The use of low-cost raw materials is a trend that has grown in scientific research. The aim of this work is to prepare membranes with hollow fiber geometry from alumina and residue of quartzite, by the technique of immersion precipitation in distilled water from a mixture of ceramic mass with a solution of polyethersulfone and, synthesized in temperatures of 1100 ºC to 1500 °C. The hollow fiber membranes were characterized by chemical analysis, X-ray diffraction, particle size distribution, scanning electron microscopy, apparent porosity, flexural strength and permeated water flow by the membranes. The results indicated that the sintering temperature has direct influence on the formation of the mullite phase, and the properties of apparent porosity and permeate flow. The higher the sintering temperature (1400-1500 ° C) increase the formation of the mullite phase, the lower the porosity, as well as the lower the permeate water flow in the membranes. However, there was increase in flexural strength in the hollow fiber membranes with high temperature.

“…It is based on the application of a pressure difference allowing the transfer of the solvent through a membrane whose pore size ensures the retention of solutes. Recently, ceramic membranes have been used intensively because of their interesting advantages [1]. In general, these membranes are made from expensive metal oxides such as alumina, silica, zircon and titanium [2][3][4][5][6].…”

Characterization and application of ceramic membranes prepared from Algerian kaolin

et al. 2019

In this study, a new ceramic membrane type was used for the filtration of colored water. The membrane was prepared from local Algerian kaolin KT2 of Milia-type. The choice of this raw material was dictated by its natural abundance, to form the macroporous support prepared by the slip casting technique. A functional thin film layer (with a pore size of about 0.2 μm) produced by the sol-gel method was deposited on the support to reduce the porosity. A detailed study was conducted because of the importance of this layer and the improvement which brought to the filtration process. Ceramic membranes were tested for the removal of bromophenol red (BR) under a filtration pressure of 3 bar and a duration of 2 h of treatment. The results revealed a rejection rate of 100% for BR, especially after the addition of the inorganic layer. The material was characterized by DTA, TGA, XRD and SEM. The retention and the permeability of BR were also studied.

In recent years, there has been a growing interest in utilizing inorganic membranes, particularly alumina (Al 2 O 3) ceramic membranes (CMs), and to address a variety of separation problems in miscellaneous industry. Al 2 O 3 membranes are commercially predominant in CMs market. Al 2 O 3 material is generally used either as membrane support and/or as membrane layer due to advantages provided by this material and its derivatives such as availability in tonnage quantities, chemical inertness, good hardness, and thermal stability of the porous texture during elaboration steps. In this chapter, we comprehensibly look at the recent studies related to desalination and water treatment by ultrafiltration (UF), nanofiltration (NF) Al 2 O 3 membrane, and highlight the separation properties of the membrane in specific environmental pollution. The influences of membrane operating conditions and water quality on the rejection of pollutant by Al 2 O 3 membrane are reported through a series of bench-level experiments.
