Book excerpt: Advanced Low-Cost Separation Techniques in Interface Science, Volume 30 helps scientists and researchers in academia and industry gain expert knowledge on how to use separation techniques at minimal cost and energy usage. It handles a broad range of highly relevant topics, including modern flotation techniques, low-cost materials in liquid-and gas-phase adsorption, new trends in molecular imprinting, graphenes in separation, nanobubbles and biopolymers in interface science, the reuse of biomaterials, green techniques for wastewaters, and modeling in environmental interfaces. The book shows that these techniques can be both attractive for both research and industrial purposes. It is intended for chemical engineers working in wastewater treatment industries, membrane industries, pharmaceutical industries, textile or tanneries industries, hybrid-topic industries and energy industries. - Focuses on cost and energy saving separation techniques in interface science - Discusses multiple techniques, including flotation, adsorption, materials synthesis, and more - Combines, in a single source, separation techniques, advanced methodologies, and the low-cost potential of the techniques - Describes techniques that are attractive for both research and industrial purposes
