Nanotechnology for water treatment and purification. [Anming Hu; Allen Apblett;] - - This book describes the latest progress in the application of nanotechnology.
BrownWalker Press Year: Not only does it find its use in nanomedicine, solar cells, sensor development and so on, but can also be effectively utilized to prevent water pollution. Nanostructured materials such as magnetic nanoparticles, carbon nanotubes, silver-impregnated cyclodextrin nanocomposites, nanostructured iron-zeolites, carbo-iron nanomaterials, photocatalytic titania nanoparticles, nanofiltration membranes and functionalized silica nanoparticles can be employed in water treatment to remove heavy metals, sediments, chemical effluents, charged particles, bacteria and other pathogens. This edited book comprises several review-style chapters written by world experts. The chapters are devoted to each of these nanotechnology based approaches:
Theory and Applications explores the unique physicochemical and surface properties of nanoparticles and highlights the advantages they provide for engineering applications.
Applications covered include the generation of fresh water from surface water and seawater, the prevention of the contamination of the environment, and the creation of effective and efficient methods for remediation of polluted waters. Each chapter covers a different nanotechnology-based approach and examines the basic principles, practical applications, recent breakthroughs and associated limitations.
This book is ideal for researchers and professionals in the fields of nanotechnology, water treatment and desalination. In addition, it is also ideal for postgraduate students, industry and government professionals, managers and policymakers.

Nanotechnology for water treatment and purification Author: Anming Hu ; Allen Apblett Publisher: Springer, Lecture notes in nanoscale science and technology , v. English View all editions and formats Summary: Furthermore, enzymes can be stabilized by producing single-enzyme nanoparticles consisting of single-enzyme molecules surrounded by a porous organic-inorganic network of less than a few nanometers thick.
All these new technologies of enzyme stabilization make enzymes even more attractive alternatives to other biofilm removal and control agents. Nanofiltration for Water and Wastewater Treatment Ismail Koyuncu and Mehmet Cakmakci Nanofiltration NF is a new type of pressure driven membrane process and used between reverse osmosis and ultrafiltration membranes.
The most different speciality of NF membranes is the higher rejection of multivalent ions than monovalent ions. NF membranes are used in softening water, brackish water treatment, industrial wastewater treatment and reuse, product separation in the industry, salt recovery and recently desalination as two pass NF system.
In this chapter, a general overview of nanofiltration membranes, membrane materials and manufacturing techniques, principles such as performance and modelling, module types, membrane characterization and applications on water and wastewater treatment were given.
The first one is based on the basic principle of osmotic pressure, while the latter makes use of molecule size for separation. Recent advances on nanotechnology are opening a range of possibilities in membrane technologies.
This chapter also reviews some of these aspects: new membrane preparation and cleaning methods, new surface and interior modification possibilities, the use of new nanostructured materials, and new characterization techniques. Electrospinning Nanofibers for Water Treatment Applications Eugene Smit Electrospinning is a highly versatile technique that can be used to create ultrafine fibres of various polymers and other materials, with diameters ranging from a few micrometers down to tens of nanometres.
The nonwoven webs of fibers formed through this process typically have high specific surface areas, nano-scale pore sizes, high and controllable porosity and extreme flexibility with regard to the materials used and modification of the surface chemistry of the fibres.
This chapter describes the combination of these features in the application of electrospun nanofibres in a variety of water treatment applications, including filtration, solid phase extraction and reactive membranes. Potential Risks of Using Nanotechnology in Water Treatment on Human Health Michele de Kwaadsteniet and Thomas Eugene Cloete The risk assessment of nanoparticles and nanomaterials is of key importance for the continous development in the already striving new field of nanotechnology.
Humans are increasingly being exposed to nanoparticles and nanomaterials, placing stress on the development and validation of reproducible toxicity tests.
Tests currently used include genotoxicity and cytotoxicity tests, and in vivo toxicity models. The unique characteristics of nanoparticles and nanomaterials are responsible for their toxicity and interaction with biological macromolecules within the human body. This may lead to the development of diseases and clinical disorders. A loss in cell viability and structure can also occur in exposed tissues as well as inflammation and granuloma formation.
