Nanotechnology, the engineering and art of manipulating matter at the nanoscale (1-100 nm), offers the potential of novel nanomaterials for the treatment of surface water, groundwater and wastewater contaminated by toxic metal ions, organic and inorganic solutes and microorganisms. At the present time many nanomaterials are under active research and development.
This timely volume reviews the current state-of-the-art research and development of different nanomaterials (nanostructured catalytic membranes, nanosorbents, nanocatalysts and bioactive nanoparticles) and their application in water treatment, purification and disinfection. The expert authors have contributed chapters focusing on the cutting-edge research in this emerging technology and its applications in microbiology and water treatment. Topics covered include the detection of microbial pathogens, nanofibers and nanobiocides in water purification, nanozymes for biofilm removal, water and wastewater treatment and reverse osmosis. Also included is a chapter dedicated to the health and environmental concerns for the use of nanotechnology in water treatment.
This book is aimed at everyone interested in nanobiotechnology, bioremediation, biodiagnostics, molecular diagnostics and environmental microbiology and is a recommended text for all microbiology laboratories.
Nanotechnology and Water Treatment: Applications and Emerging Opportunities
Jacques Theron, Joseph Adrian Walker and Thomas Eugene Cloete
Nanotechnology, the engineering and art of manipulating matter at the nanoscale (1-100 nm), offers the potential of novel nanomaterials for treatment of surface water, groundwater and wastewater contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. Due to their unique activity toward recalcitrant contaminants and application flexibility, many nanomaterials are under active research and development. Accordingly, literature about current research on different nanomaterials (nanostructured catalytic membranes, nanosorbents, nanocatalysts and bioactive nanoparticles) and their application in water treatment, purification and disinfection is reviewed. Moreover, knowledge regarding toxicological effects of engineered nanomaterials on humans and the environment is presented.
Current Molecular and Emerging Nanobiotechnology Approaches for the Detection of Microbial Pathogens
Jacques Theron, Thomas Eugene Cloete and Michele de Kwaadsteniet
An adequate supply of safe drinking water is one of the major prerequisites for a healthy life, but waterborne diseases is still a major cause of death in many parts of the world, particularly in young children, the elderly, or those with compromised immune systems. As the epidemiology of waterborne diseases is changing, there is a growing global public health concern about new and reemerging infectious diseases that are occurring through a complex interaction of social, economic, evolutionary, and ecological factors. An important challenge is therefore the rapid, specific and sensitive detection of waterborne pathogens. Presently, microbial tests are based essentially on time-consuming culture methods. However, newer enzymatic, immunological and genetic methods are being developed to replace and/or support classical approaches to microbial detection. Moreover, innovations in nanotechnology and nanosciences are having a significant impact in biodiagnostics, where a number of nanoparticle-based assays and nanodevices have been introduced for biomolecular detection. Accordingly, current and emerging molecular approaches for the detection of microbial pathogens as well as nanobiotechnologies that that will extend the limits of current molecular diagnostics are discussed.
Electrospun nanofibers and nanobiocides show potential in the improvement of water filtration membranes. Biofouling of membranes caused by the bacterial load in water reduces the quality of drinking water and has become a major problem. Several studies showed inhibition of these bacteria after exposure to nanofibers with functionalized surfaces. Nanobiocides such as metal nanoparticles and engineered nanomaterials are successfully incorporated into nanofibers showing high antimicrobial activity and stability in water. Research on the applications of nanofibers and nanobiocides in water purification, the fabrication thereof and recently published patents are reviewed in this article.
