dc.description.abstractIn wastewater treatment, the development of low-cost separation methods is of significant importance. Low-cost membranes based on natural materials have become a highly active research topic in recent years. Herein, using low-cost natural Moroccan sand, new ceramic supports have been developed and characterized using different techniques such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), differential thermal analysis (DTA) ), along with scanning electron microscope (SEM). Plastic paste (average particle size ˂ 125 mm) was blended with organic additives and water, then the obtained paste was extruded into porous tubular supports. The support had a porosity of 43%, water permeability of 1928 L/hm(2) bar, excellent chemical and mechanical properties and an average pore diameter in the range of 8-15 mm after firing at 950 ?/2 h. As per SEM analysis, the tubular supports had a smooth and crack-free surface. The slip casting process was used to create a microfiltration layer from the same natural sand powder (average particle size ˂ 63 mm) using a mixture of powder sand, water, and polyvinyl alcohol solution. The water permeability of the microfiltration membrane sin-tered at 950 & DEG;C/2 h was 1052 L/h m2 bar, the average pore size diameter was about 0.90 mm and 82% of pores had a diameter ˂ 1.00 mm. The obtained microfiltration membrane was tested for the treatment of urban wastewater. The membrane showed excellent separation performance in turbidity removal and chemical oxygen demand.(c) 2022 The Author(s).
