“…Use of oxides of pure Al 2 O 3 , TiO 2 , ZrO 2 , SiO 2 or their combinations for the preparation of ceramic membranes [5,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] with high chemical, mechanical and thermal stabilities are well established [27,28] and are common, but the use of high cost inorganic precursors to obtain these oxides increases the cost as well as requires high sintering temperature (>1100 • C) for fabrication. The use of cheaper precursors such as ball clay, kaolin, quartz, feldspar, CaCO 3 , clay, sand and pyrophyllite for preparation of microfiltration range ceramic membranes have been reported [29,30].…”

In the present day scenario, the crisis of safe drinking water is an extremely serious issue across many parts of the globe and needs efficient methods to overcome this problem. The effort made in this study is to develop a method to prepare a ceramic membrane with locally available cheap compositions such as potters' clay, stone dust and tea waste materials for efficient adsorptive dye removal from water. The preparation of ceramic membrane was carried out by a paste pressing method and sintered at an optimized temperature of 900 • C to obtain flat ceramic membranes of 42 mm in diameter and 3±0.5 mm thickness with good thermal and chemical stabilities with 52.51% porosity and average pore size of 0.49 μm. The membrane was capable of decolouring methylene blue and congo red from water with good efficiency and the used membrane was regenerated by calcining at 400 • C for 30 min without much loss of its efficiency. Development of newer advanced products with the available local resources may be another way to sustain the small scale industry and livelihood of the people around.

“…Based on molecular size and shape, the rigid ceramic structure and precise tuning of the pore sizes endow inorganic membranes great capabilities for separation processes. For example, Singh et al [ 104 ] proposed cetyltrimethylammonium bromide (CTAB)—silica membrane with flat and hollow fiber polysulfone structure. At 25 °C, when 40 g/L NaCl seawater is pervaporated by the membrane and the salt resistance rate can reach 99.9%.…”

Membrane separation technologies have attracted great attentions in chemical engineering, food science, analytical science, and environmental science. Compared to traditional membrane separation techniques like reverse osmosis (RO), ultrafiltration (UF), electrodialysis (ED) and others, pervaporation (PV)-based membrane separation shows not only mutual advantages such as small floor area, simplicity, and flexibility, but also unique characteristics including low cost as well as high energy and separation efficiency. Recently, different polymer, ceramic and composite membranes have shown promising separation applications through the PV-based techniques. To show the importance of PV for membrane separation applications, we present recent advances in the fabrication, properties and performances of polymeric membranes for PV separation of various chemicals in petrochemical, desalination, medicine, food, environmental protection, and other industrial fields. To promote the easy understanding of readers, the preparation methods and the PV separation mechanisms of various polymer membranes are introduced and discussed in detail. This work will be helpful for developing novel functional polymer-based membranes and facile techniques to promote the applications of PV techniques in different fields.

“…Similar to the selection of membrane materials for gas dehydration processes [19], most membranes tested to date for PV desalination are based on hydrophilic materials to enhance the solubility component to water transport. Specifically, PV desalination studies were performed with polyether-polyamide block copolymer (PEBAX) [20][21][22], cellulose-based [23][24][25][26], polyvinyl alcohol-based (PVA) [27][28][29][30][31][32][33], graphene oxide (GO) [34][35][36], sulfonated block copolymers [37,38], ion-exchanged polyethylene [39], inorganic [40][41][42][43][44][45][46][47][48][49][50][51], and mixedmatrix/hybrid [32,[52][53][54][55]] active layers. For example, Li et al [35] synthesized a GO active layer on polyvinylidene fluoride (PVDF) support and reported a pure-water flux value of 67 kg m -² h -1 at 70 °C.…”
