“…Similar phases were also identified by Dong et al [20] for pure TiO 2 . In the fly ash, the observed crystalline phases are quartz (SiO 2 ) and corundum (Al 2 O 3 ) which are consistent with the results reported by Jedidi et al [36]. It is also noticed that in the fly ash sample, the intensity of quartz peak decreases due to the conversion of quartz to corundum at the sintering temperature.…”

A B S T R A C TThis work addresses the fabrication of ceramic microfiltration membranes by uniaxial dry compaction method. Four membranes, namely SP1, SP2, SP3, and SP4 were prepared with various compositions of fly ash and titanium dioxide (TiO 2 ) followed by sintering at 1,100˚C. The raw materials and the prepared membranes were characterized by particle size distribution, X-ray diffraction and field emission scanning electron microscope, porosity, pore size, and chemical and mechanical stabilities. As the TiO 2 content increases in the precursor formulations, the porosity and mechanical stability of the membranes also increase while the average pore size reduces from 2.97 to 1.32 μm. The chemical stability of all the membranes demonstrates to be better in both acidic and basic medium. The performance of the membrane (SP4) is examined for the separation of oil-water emulsion and the membrane exhibits a maximum oil rejection of 99.2%.

“…It can be estimated that the total material cost for a length of 24 cm CS-PC16 is only 9.70 $, while that for the standard ceramic membrane (50 nm) with the same length, the cost has attained as high as 24.12 $, which is almost 2.5 times higher than that of composite membranes. Moreover, the cost of composite membranes could be reduced further by applying the low cost supports fabricated with fly ash, or natural phosphate, or kaolin and calcite [34][35][36][37].Considering the convenient preparation process and low cost, the composite membrane is highly competitive with commercial ceramic membranes in the MF applications.…”

“…MBR membranes and filters are usually made of organic polymer or inorganic ceramics; however, alternative materials such as clay, fly ash, coarse meshes and fabrics have also been considered for use in MBRs to reduce the membrane cost and the fouling phenomena associated with conventional membranes (Tewari et al, 2010;Jedidi et al, 2011;Zahid and El-Shafai, 2011;Wang et al, 2012). A simple ceramic filter made with locally available and cheap materials (clay soil and rice bran) was developed for arsenic removal from groundwater .…”

To explore the cost reduction of water reclamation and reuse facilities in developing countries, a simple ceramic filter made of local materials, such as clay and rice bran, was used in a membrane bioreactor (MBR) process. The feasibility of applying suction filtration to an MBR with a simple ceramic filter was examined by a laboratory-scale experiment; successful results using gravity filtration were reported in a previous paper. The BOD removal performance was satisfactory and demonstrated the feasibility of reusing effluent water for many purposes. The MBR operation with a flux less than 0.2 m/d showed a lower risk of fouling; increasing the flux caused an increase in fouling risk. The suction filtration and gravity filtration results were compared using the total resistance of the filter (R) and the resistance change rate (dR/dt). The R and dR/dt values were estimated higher in the suction filtration compared to those in the gravity filtration. The high dR/dt seemed to cause the necessity of the filter cleaning. The gravity filtration was suggested to be a more advantageous operation than the suction filtration in MBR using the simple ceramic filter.
