Advances in membrane technologies for water treatment : by Angelo Basile, Alfredo Cassano, Navin K Rastogi

By Angelo Basile, Alfredo Cassano, Navin K Rastogi

Membrane fabrics permit for the selective separation of gasoline and vapour and for ion shipping. fabrics examine and improvement keeps to force advancements within the layout, manufacture and integration of membrane applied sciences as serious elements in either sustainable strength and fresh purposes. Membrane utilisation bargains approach simplification and intensification in undefined, delivering inexpensive, and effective and trustworthy operation, and contributing in the direction of emissions discount rates and effort safety. complex membrane technology and know-how for sustainable power and environmental purposes provides a accomplished overview of membrane utilisation and integration inside power and environmental industries.

Part one introduces the subject of membrane technological know-how and engineering, from the basics of membrane procedures and separation to membrane characterization and fiscal research. half makes a speciality of membrane utilisation for carbon dioxide (CO2) seize in coal and fuel strength crops, together with pre- and post-combustion and oxygen delivery applied sciences. half 3 reports membranes for the petrochemical undefined, with chapters overlaying hydrocarbon gasoline, traditional fuel and synthesis fuel processing, in addition to complicated biofuels construction. half 4 covers membranes for replacement strength functions and effort garage, comparable to membrane expertise for redox and lithium batteries, gasoline cells and hydrogen construction. ultimately, half 5 discusses membranes utilisation in business and environmental functions, together with microfiltration, ultrafiltration, and ahead osmosis, in addition to water, wastewater and nuclear energy applications.

With its individual editors and workforce of professional participants, complex membrane technological know-how and know-how for sustainable power and environmental purposes is an important reference for membrane and fabrics engineers and brands, in addition to researchers and teachers drawn to this field.

  • Presents a entire evaluation of membrane technological know-how and expertise, targeting advancements and functions in sustainable strength and clean-industry

Microfiltration and Ultrafiltration Membranes in Drinking Water

This fresh handbook offers thorough assurance of water membrane technology, strategies, and thought. Chapters speak about membrane functions, trying out of membrane structures, layout techniques and operations, bills, residuals, plus some of the manufactures. the ultimate bankruptcy covers destiny developments in low-pressure membranes via broad tables and figures

Energy Use in Global Food Production: Considerations for Sustainable Food Security in the 21st Century

​This short examines the sustainability of power use in international meals construction and processing. The nexus among foodstuff, water, and effort are explored opposed to a history of weather swap. present efforts to lessen the power depth of foodstuff and elevate sustainability are explored. nutrients waste and its effect on strength is roofed, together with nearby diversifications and nutrient recycling tools.

Wastewater and shale formation development : risks, mitigation, and regulation

This identify incorporates a variety of Open entry chapters. The variety of tight oil and shale fuel wells keeps to upward push basically within the US, but additionally world wide. the USA has large reserves of oil and usual gasoline, which now are commercially on hand due to advances in horizontal drilling and hydraulic fracturing applied sciences.

Bio-inspired membranes have great benefits such as high permeability, catalytic reactivity, and fouling resistance, and hence have the potential to be employed in water treatment processes. Pan et al. (2010) proposed an innovative procedure to fabricate a polymereinorganic skin layer of a composite membrane by combining bio-mimetic mineralization and Advances in polymeric membranes for water treatment 27 polymer network structure manipulation. In this work, the silica nanoparticles showed uniform size and homogeneous distribution within the PVA structure.

2010) prepared a TFC PA nanofiltration membrane using interfacial polymerization of PDA with TMC. The TFC polyamide membranes displayed a higher ability to soften water. The composite membrane exhibited water permeability of 7 and 21 kg/m2 h for salt solution containing NaCl (1 g/l) and MgSO4 (1 g/l) at 5 and 10 bar, respectively. Also, rejection of the divalent salt MgSO4 (85% and 90%) was high compared with the monovalent salt NaCl (64% and 67%) at 5 and 10 bar, respectively. In other research, Han, chang, et al.

(2009) synthesized organiceinorganic PVDFeSiO2 composite hollow fiber ultrafiltration membranes using a sol-gel and wet-spinning process. The microstructure, mechanical property, thermal stability, hydrophilicity, permeability, and fouling resistance of composite membranes improved significantly by an appropriate choice of TEOS concentration (3 wt%). The phase inversion process was also used by researchers as a simple and applicable technique to prepare polymeresilica-mixed matrix membranes.
