Elaboration of a new flat membrane support from Moroccan clay

Abstract

A B S T R A C TThe present paper is devoted to synthesis of porous ceramic support from local Moroccan clay (region of Agadir). This material has been dictated by their natural abundance (low price) and their beneficial properties. In this work, we were also interested in the development and the characterization of new mineral support for microfiltration and ultrafiltration membrane. The support, with flat configuration, was prepared from natural clay: the powder was crushed, sieved to 125 lm and mixed with organic additives and water. The obtained paste was then extruded to elaborate a porous structure. The firing temperature of the support is 800 C. After firing, the elaborated support showed an average pore diameter of 11 lm and a porosity of 41%. The average support permeability determined using pure distilled water is 1,805 L/h m² bar. This porous ceramic tube was used as support to prepare microfiltration membrane which were tested for the filtration.

Preparation and characterization of low cost flat ceramic membranes from easily available potters’ clay for dye separation

“…Ceramic filters and membranes have been extensively applied in a number of fields, such as food and beverage, biotechnology and pharmaceuticals, bulk and fine chemicals, waste recovery and recycling industries [1][2][3][4]. The ability of ceramic membranes to uniquely address the distinct need of frequent cleaning, high resistance to harsh operating environment and continuous flow conditions are some of their main advantages over other types of membranes or porous barriers [5].…”

Flexible Synthesis of Bio-Hydroxyapatite/Chitosan Hydrogel Beads for Highly Efficient Orange G Dye Removal: Batch and Recirculating Fixed-Bed Column Study

“…9,10 Numerous studies are being conducted to discover low-cost, eco-friendly materials to eliminate pollutants in aqueous environments. 11 Crucial importance has been gained on the biomaterials as adsorbents to remove contaminants, which can reduce the process cost substantially and make the adsorption method more ecological and feasible. 12 The encapsulated materials have gained significant attention in recent years as effective adsorbents for the removal of dyes from wastewater.…”

Review on natural clay ceramic membrane: Fabrication and application in water and wastewater treatment

“…Thus, the fabrication of low cost ceramic membrane based on the natural clay (e.g. kaolino-illitic clay, smectetic clay, Moroccan pozzolan clay) was studied by several researchers due to their abundance in nature (Ali et al, 2018;Misrar et al, 2017;Achiou et al, 2016;Baraka et al, 2014). New flat ceramic microfiltration membranes were recently developed from abundant, natural materials such as natural Moroccan bentonite for industrial wastewater treatment (Bouazizi et al, 2016).…”
