“…Algeria is one of the countries in the world that have abundantly available raw materials, such as calcium carbonates (CaCO 3 )(CC), dolomite (CaCO 3 ·MgCO 3 ), bones (natural derived hydroxyapatite (HA): Ca 10 (PO 4 ) 6 (OH) 2 ), kaolin, feldspar and quartz. Many works have already been published for valorizing these native raw materials, for the production of advanced ceramics [1][2][3][4][5][6][7], ceramic membranes [8][9][10][11][12][13][14][15][16][17][18][19] and bioceramics [20][21][22][23][24][25][26][27]. In particular, in the membrane field the possibility of replacing the more expensive starting materials by cheaper raw materials to be used as a support (which constitutes about 99% of the filter mass) is significantly important from economic and energetic points of view.…”

“…Inorganic membranes are gaining a lot of interest in the recent years, thanks to the development of new types of inorganic membranes [28][29][30][31][32][33][34][35][36][37]. The inorganic membranes have excellent high thermal, chemical stability, mechanical resistance [8,13,[38][39][40][41][42][43], a longer life-time, ease of cleaning, a low thermal conductivity and a low dielectric constant [43,44]. Furthermore, these membranes are found to be able to resist corrosive highly acids and alkali media as well as to withstand high pressure applications.…”

The preparation and characterization of porous tubular ceramic composite microfiltration membranes, using kaolins and calcium carbonates, were reported. The porous gehlenite (2CaO·Al 2 O 3 ·SiO 2 ) and anorthite (CaO·Al 2 O 3 ·2SiO 2 ) based ceramics were obtained by a solid state reaction. A ceramic support, sintered at 1250°C, within an average pore size of about 8 μm, a porosity of about 47% and a compression strength around 40 MPa, was prepared. The microfiltration active top layer was added on the support by a slip casting from clay powder suspensions. The novel microfiltration membrane layer has a thickness of 40 μm and an APS value of about 0.2 μm. This average pore size value was improved and considerably lower than those reported in the literature (0.5 μm). The performance of the novel microfiltration ceramic membrane was determined for evaluating both the water permeability and rejection. This proved the potentiality of the membrane produced in the microfiltration field. Moreover, the good adhesion, between the support and the active microfiltration layer membranes, was also proved. A correlation between microstructures of used powders and physicochemical properties was discussed. Finally, the origin of the unique two powder order membrane depositions was also proposed.

Recently, porous ceramic membranes have become a subject of significant interest due to their outstanding thermal and chemical stability. To reduce the high manufacturing costs of these porous ceramic membranes, recent research has focused on the utilization of low-cost natural materials. Therefore, in this paper, we report the results of an attempt to prepare a diatomite-kaolin composite support layer that could effectively filter the ISO 12103-1 A3 test dust while exhibiting acceptable water permeability. The pore characteristics of the specimens were studied by scanning electron micrography, mercury porosimetry, capillary flow porosimetry, and a dead-end microfiltration system with particle counters.

“…Generally, commercial ceramic membranes are prepared from amphoteric oxides such as alumina, titania, zirconia [2][3][4][5][6], and sometime also with carbone which is in expensive precursor to fabricate the membrane, Yachino 2005 [7]. To avoid the issue of membrane cost, resent research in the fabrication of inorganic membrane is focused towards of utilization of cheaper raw materiels.…”

Abstract. This paper is devoted the preparation of low cost microfiltration membranes using Moroccan clay powder. The preparation of membrane was composed with two steps: First a macroporous tubular support with a pore diameter 10 µm and porosity 43%. Secondly a microfiltration layer was performed by the slip casting method. A deflocculated slip was obtained by mixing mineral powder of ZrO2, PVA (polyvinyl alcohol) and water, after drying at room temperature for 24 h, the microfiltration layer was heated to 800°C for consolidation. Scanning electron microscopy observation showed homogeneous layers without cracks with an average pore diameter of 0.19 µm for the active layer. Water permeability obtained is about 841 L/h.m2.bar. The membranes have been tested to cleaning of colored wastewater.
