Compiling recent advances in membrane separations technology, this highly relevant book introduces cost-effective solutions for separation problems in a wide range of industries. It discusses membrane use in oil, petrochemicals, and fossil fuels; natural gas exploration; bioseparation; water purification and wastewater treatment; and chemical manufacturing. It describes the role of membrane technologies in resource recovery, pollution prevention, and energy production, as well as environmental monitoring and quality control. A concise resource for emerging technologies, this book provides the...

A novel multi-stage external loop airlift reactor (MS-ELALR) has been designed to remove phenol and Cr(VI) from wastewater by means of their adsorption onto the surface of activated carbons. The multi-staging has been achieved by hydrodynamically induced continuous bubble generation, breakup and regeneration. The typical values of gas holdup, liquid circulation velocity, interfacial area and volumetric mass transfer coefficient of the MS-ELALR were found to be 0.42-0.66, 0.04-0.13 m/s, 70-300 m2/m3 and 0.01-0.5 s-1 respectively. Powdered activated carbons were prepared from four different...

As India progresses fast in the 21st century, we also face daunting challenges of energy security and climate change. Tremendous development in various sectors like industry, agriculture, transport has resulted in huge rise in demand for energy. Fulfilling these demands through conventional fossil fuel based energy generation has given rise to significant emissions (both gaseous and liquids) that have caused pollution to atmosphere and aquatic eco-systems. Use of sustainable and green (or renewable) resources and technologies offers a viable and promising solutions to these issues. Last two...
