“…Therefore, the trend observed in Fig. 7 is in opposite relation for gases, where the permeability vs. pressure is initially constant and then increases [17]. Comparing our results with the others shows that the permeate flux obtained for our nanomembrane is twice the flux reported in the work of Costa et al at almost the same applied pressures [18].…”

A B S T R A C TThe γ-alumina and titania nanocrystallites were coated by sol-gel method on alumina supports respectively, as sub-layer and top-layer to prepare nanomembranes. The analysis represented a meso-porous structure for the coating layers of nanomembrane with the average pore size of 5.8 nm. The performance of the nanomembranes was investigated for permeability of demineralized water as well as rejection of ions and microorganisms using a model wastewater. Results show that in the range of 1-10 bar applied pressure, the permeability was reduced. At higher than 10 bars, with the increase of pressure, the permeability almost stayed constant due to the increase of flux. The multilayer nanomembranes showed different rejections for ions up to 25% but completely separation of the microorganisms.

“…The dip coating technique is a simple, fast, versatile, cheap approach in fabrication of the colloidal particles coatings and the sol-gel thin films which applied to various fields. [104][105][106][107] Usually the deposition operations of the dip coating are completely automated by control system. The control of layer thickness can be realized by Landau-Levich's Eq.…”

In recent years, there has been a growing interest in the self-assembly process for the fabrication of micro- and nano-scale structures for various device applications. The success of these applications requires the development of a versatile assembly process for producing large area ordered arrays. In this article, we review recent advances, particularly related to photonic material and device applications, based on self-assembly processes, with the focus on the processes for inorganic structure self assembly. We first discuss major forces guiding the particle self-assembly in the wet coating technology. Then we review device applications and recent advances based on three kinds of wet coating technologies, including dip coating, spin coating and convective coating. Finally, a conclusion will be given, with discussions given on future perspectives.

“…(1) and (2)): [27]. Furthermore, multi-layer composite membranes with an asymmetric structure can be processed using coating techniques [28]. It is worth to mention that Al 2 O 3 membranes (MF, UF, and NF) have naturally hydrophilic character due to the presence of an oxide material in the hydroxyl group.…”

In recent years, there has been a growing interest in utilizing inorganic membranes, particularly alumina (Al 2 O 3) ceramic membranes (CMs), and to address a variety of separation problems in miscellaneous industry. Al 2 O 3 membranes are commercially predominant in CMs market. Al 2 O 3 material is generally used either as membrane support and/or as membrane layer due to advantages provided by this material and its derivatives such as availability in tonnage quantities, chemical inertness, good hardness, and thermal stability of the porous texture during elaboration steps. In this chapter, we comprehensibly look at the recent studies related to desalination and water treatment by ultrafiltration (UF), nanofiltration (NF) Al 2 O 3 membrane, and highlight the separation properties of the membrane in specific environmental pollution. The influences of membrane operating conditions and water quality on the rejection of pollutant by Al 2 O 3 membrane are reported through a series of bench-level experiments.
