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 fuel and vapour and for ion delivery. fabrics study and improvement keeps to force advancements within the layout, manufacture and integration of membrane applied sciences as serious elements in either sustainable power and fresh purposes. Membrane utilisation deals approach simplification and intensification in undefined, supplying inexpensive, and effective and trustworthy operation, and contributing in the direction of emissions discount rates and effort defense. complicated membrane technological know-how and expertise for sustainable strength and environmental functions offers a entire evaluation 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 strategies and separation to membrane characterization and financial research. half makes a speciality of membrane utilisation for carbon dioxide (CO2) catch in coal and fuel energy vegetation, together with pre- and post-combustion and oxygen shipping applied sciences. half 3 reports membranes for the petrochemical undefined, with chapters overlaying hydrocarbon gas, common fuel and synthesis gasoline processing, in addition to complicated biofuels construction. half 4 covers membranes for replacement strength purposes and effort garage, resembling membrane know-how for redox and lithium batteries, gas cells and hydrogen creation. eventually, 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 extraordinary editors and workforce of specialist members, complex membrane technology and expertise 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 complete overview of membrane technological know-how and know-how, targeting advancements and functions in sustainable power and clean-industry

Implementing Integrated Water Resources Management in Central Asia (NATO Science Series: IV: Earth and Environmental Sciences)

The issues afflicting the Aral Sea and its environs end result of the overuse and abuse of the rivers flowing into it are good documented. before, even though, it used to be tricky to listen to the voices of these accountable for truly coping with these waters. This quantity reproduces the lawsuits of a complicated examine Workshop held in Bishkek, which introduced jointly all of the such a lot senior water source managers in important Asia, from Ministers to neighborhood specialists and eminent teachers.

Calcium and Magnesium in Groundwater: Occurrence and Significance for Human Health

Calcium and magnesium are plentiful in groundwater, however the position of groundwater because the crucial resource of those very important meals is particularly frequently missed. Hydrogeochemical reports have centred mostly at the distribution and behavior of materials that reason deterioration of water caliber, similar to: nitrate, nitrite or iron and manganese.

Practical Design Calculations for Groundwater and Soil Remediation, Second Edition

  comprises Illustrative functions of useful layout Calculations Written in a simple kind and hassle-free structure, useful layout Calculations for Groundwater and Soil Remediation, moment version highlights the basic suggestions and critical elements of significant layout calculations utilized in soil and groundwater remediation.

Air pollution and freshwater ecosystems : sampling, analysis, and quality assurance

A pragmatic ebook for pros who depend on water caliber info for selection making, this ebook relies on 3 many years adventure of 3 hugely released water and watershed source execs. It makes a speciality of the research of pollution delicate waters and the ensuing results linked to soil and water acidification, nutrient-N enrichment, or the consequences of atmospherically deposited poisonous ingredients.

According to this study, the organic phase reactants had a considerable impact on membrane performance compared with the aqueous phase reactant. 7 l/m2 h) when tested using a 2000 ppm NaCl solution at 2 MPa. The rougher and larger surface area of the op-BTEC membrane, which led to greater contact with water molecules, was reported as the reason for the flux enhancement of this membrane (Li , Zhang, Zhang, & Zheng, 2008). In another study, Chen, Li, Zhang, and Zhang (2008) synthesized a new class of polymeric amine, named SPES-NH2, which was applied for the preparation of TFC reverse osmosis membranes.

They declared that the addition of OMMT can be effective in considerably improving membrane hydrophilicity and thermal and mechanical resistance as well as pesticide retention capability at different solution conditions (acidic and neutral). In similar work, Mierzwa, Arieta, Verlage, Carvalho, and Vecitis (2013) investigated the effect of incorporating unmodified clay nanoparticles (single platelet MMT) with and without sodium hexametaphosphate as a clay nanoparticle dispersant into the casting solution on the morphology and performance of PES ultrafiltration membranes.

3 Schematic of the reaction between g-Al2O3 and poly(vinylidenefluoride) polymer. Reprinted from Liu, Moghareh Abed, and Li (2011), with permission from Elsevier. 22 Advances in Membrane Technologies for Water Treatment In studies conducted by Maximous, Nakhla, Wan, and Wong (2009) and Maximous, Nakhla, Wan, et al. (2010), PES membranes were modified by inserting different concentrations of nanosized alumina (48 nm) particles inside the polymer matrix. The increase in porosity and decrease in the hydrophobic interaction between membrane surface and foulants changed the performance of the PES membrane after adding Al2O3 nanoparticles into the casting solution.
