Current development of membrane technology for purifying polluted water and wastewater is discussed in this review in accordance with its hybrid application with other types of water treatment methods such as adsorption, advanced oxidation processes (AOPs), and biological activated sludge. This hybrid implementation aims are to lengthen membrane lifespan and elude severe fouling on the surface and pore of the membrane. Membrane material and fabrication technology were concisely included. Two prominent materials to fabricate membrane namely polymeric and ceramic are reviewed well along with the exploration of biopolymers based-materials such as starch and alginate. Several fabrication methods available to be implemented in research or industrial large scale including interfacial polymerization technique, non-solvent induced phase separation, temperature induced phase separation, electrospinning, and sintering are deliberately discussed. The next section includes fouling analysis involving reliable fouling mechanism namely Hermia’s models to help with the explanation of fouling occurrence during filtration. These models covers four different mechanisms namely complete blocking, standard blocking, intermediate blocking, and cake filtration models. Ultimately, recent research reporting the outcome of the hybridization of membrane and adsorption, biosorption, coagulation-flocculation, AOPs, and biological treatment using microorganism were properly reviewed. Overall, this review considerably promotes the findings of those works which mostly revealed positive outcome of the hybrid membrane system contributing to stronger foundation for future research.

“…Cost analysis of ceramic membrane fabrication has estimated that 60% came from energy consumption in the sintering process, 20% from material costs, and the remaining 20% from labor costs. 29 This provided an incentive to lower fabrication costs by either reducing sintering temperature or sintering time. To reduce the sintering temperature, low meting point materials such as kaolin, 30 fly ash, 31 and clays 32 were used as sintering additives.…”

Melded ceramic membranes: A novel fabrication method for ultrathin alumina membranes of high performance

Conventional ceramic membranes are usually fabricated on porous ceramic substrates, using a repetitive coating-sintering process to form a multilayered structure. This results in lengthy fabrication periods and high fabrication costs. In this work, we developed a novel fabrication process, melding, by combining vacuum infiltration and pore tuning techniques to directly construct the ceramic membrane layer within the porous ceramic substrate. By careful selection of powder sizes, the detrimental penetration effect can be modified into a benefit, forming an ultrathin membrane layer with thickness less than 1.45 µm after sintering at 1200 • C. Compared favorably with dip-coated ceramic membranes, the melded ceramic membrane had much smaller nominal pore sizes (0.19 vs 0.31 µm), but much higher water permeance (>60%). The melded ceramic membrane also had the highest rejection (98.5%) toward 125 nm polystyrene latex suspensions (2 ppm), highest sustained oil removal efficiency (>90%) under oilin-water emulsion (200 ppm) filtration, and the least irreversible fouling (<8.6%). The melding process also significantly reduced the raw powders required, leading to an 86% reduction in material costs, as compared to the multilayered ceramic membranes.

“…Ceramic membranes have attracted more and more attention due to their outstanding properties, such as their high mechanical strength, their superior chemical/thermal resistance, the easy cleaning of membrane, and, consequently, their extended operating life [7]. However, their high manufacturing costs-especially that of the energy-intensive powder-sintering process-have limited their wider application [8,9]. As a suitable alternative to the conventional powder process, ceramic structures with compositions such as Si-O-C, Si-C and Si-(B)-N-C can be synthesized through the cross-linking and pyrolysis of a suitable polymeric precursor at lower processing temperatures than the ones required for the sintering process [10].…”

Influence of the Pyrolysis Temperature and TiO2-Incorporation on the Properties of SiOC/SiC Composites for Efficient Wastewater Treatment Applications

This study focuses on the development of porous ceramer and SiOC composites which are suitable for microfiltration applications, using a mixture of polysiloxanes as the preceramic precursor. The properties of the membranes—such as their pore size, hydrophilicity, specific surface area, and mechanical resistance—were tailored in a one-step process, according to the choice of pyrolysis temperatures (600–1000 °C) and the incorporation of micro- (SiC) and nanofillers (TiO2). Lower pyrolysis temperatures (<700 °C) allowed the incorporation of TiO2 in its photocatalytically active anatase phase, enabling the study of its photocatalytic decomposition. The produced materials showed low photocatalytic activity; however, a high adsorption capacity for methylene blue was observed, which could be suitable for dye-removal applications. The membrane performance was evaluated in terms of its maximum flexural strength, water permeation, and separation of an oil-in-water emulsion. The mechanical resistance increased with an increase of the pyrolysis temperature, as the preceramic precursor underwent the ceramization process. Water fluxes varying from 2.5 to 370 L/m2·h (2 bar) were obtained according to the membrane pore sizes and surface characteristics. Oil-rejection ratios of 81–98% were obtained at an initial oil concentration of 1000 mg/L, indicating a potential application of the produced PDC membranes in the treatment of oily wastewater.
