“…Surface modification such as self‐assembly and radiation induced polymerization and blending of membrane materials with modifiers such as copolymers and nano‐particles are the most common approaches for the membrane performance enhancement . Various inorganic particles such as holloysite nanotube clay, TiO 2, Al 2 O 3, ZnO, SiO 2, Fe 3 O 4, CaO 3 and addition of metal‐organic frame work (MOF) have been utilized to fabricate inorganic‐polymer composite membranes. Scrutiny of the literatures reveals that silica nano‐particles are the most popularly used filler for improving membranes performance.…”

In the present paper, hierarchically structured ultrafiltration polysulfone (PSf) membrane was prepared to explore the effect of addition and subsequent removal of SiO 2 nano-particles on the membrane morphology, hydrophilicity, and separation properties. The PSf based membranes namely PSf, PSf/SiO 2 and PSf/WSiO 2 (i.e. SiO 2 nano-particles was acid-washed and removed from PSf/SiO 2 ), were synthesized and characterized by different characterization methods. Pure water flux through the membranes was determined using a filtration unit operating at a continuous dead-end flow mode. The modification enhanced the morphology, hydrophobicity, porosity and transport properties of the modified membranes, although the molecular weight cut-off (MWCO) of the membranes was not changed considerably. In comparison, PSf/WSiO 2 membrane exhibited excellent pure water flux (about 4.5 times the flux of PSf, and 17 times the flux of PSf/SiO 2 ), although antifouling property of PSf/SiO 2 in separation of bovine serum albumin (BSA) was better than that of PSf and PSf/WSiO 2 membranes. The results suggested that the addition/removal of sacrificial solid fillers within/from a membrane matrix may provide a promising strategy to enhance PSf membrane transport property.

“…However, the photocatalyst has to be transferred to the membrane module for separation, making it easy for photocatalyst to deposit in the corner of the pipeline, ultimately affecting photocatalytic performance. Figure 7 presents a typical split-type PMR with suspended photocatalyst [65]. A UV lamp with the peak wavelength of 253.7 nm was placed inside the reactor.…”

Abstract:The lack of access to clean water remains a severe issue all over the world. Coupling photocatalysis with the membrane separation process, which is known as a photocatalytic membrane reactor (PMR), is promising for water treatment. PMR has developed rapidly during the last few years, and this paper presents an overview of the progress in the configuration and operational parameters of PMRs. Two main configurations of PMRs (PMRs with immobilized photocatalyst; PMRs with suspended photocatalyst) are comprehensively described and characterized. Various influencing factors on the performance of PMRs, including photocatalyst, light source, water quality, aeration and membrane, are detailed. Moreover, a discussion on the current problems and development prospects of PMRs for practical application are presented.

“…Zinc oxide is one of the most important functional oxides that has been conventionally applied as photocatalyst owing to its direct band gap, large excitation binding energy and good carrier mobility. Hairom et al (2014) applied zinc oxide nanoparticles in the heterogeneous photocatalytic reaction and achieved nearly 95% of Congo red dye removal. Besides, Hong and He (2012) successfully embedded zinc oxide into polyvinylidene fluoride (PVDF) microfiltration membrane and improved the hydrophilicity of the membrane.…”
