Emerging Nanotechnologies for Water Treatment
The physical and chemical properties of nanomaterials may be tailored to environmental application in water quality monitoring and water treatment.
|
Technology plays a vital role in water purification. It may be deployed removing harmful substances and pathogens to ensure water wholeness, or preventing oxygen depletion in receiving waters because of organic matter and nutrients in sewage. Innovation is critical to keep up with growing water demands and to protect the environment. To address these issues, the water sector must not only upgrade current treatments, but also seek new decentralised, highly efficient and multifunctional processes. The editors of this book discuss promising technologies bridging the nanoworld and full-scale water treatments. Written as stand-alone literature reviews, the 17 chapters and over 500 pages summarise information on the synthesis and characterisation of nanomaterials deployed in filtration, adsorption, catalysis, and disinfection. The editors have curated contributions from experts, ensuring the scientific accuracy and applicability of the content. To help the reader’s navigation through this collection, however, a table of contents grouping the chapters into topics is needed. For example: ‘monitoring’, ‘adsorption’, ‘advanced oxidation processes,’ and ‘other processes’. |

Readers will gain insights into (1) synthesis and properties of nanomaterials tailored to improve water purification efficiency, and (2) cutting-edge applications such as photocatalysis, nanosensors for quality monitoring, and hybrid nanotechnology-based systems. Discussion on regulatory frameworks and nanomaterial risks in water systems could have added value.
Application to full-scale water treatments is discussed in two key chapters, which thus deserve special mention. Chapter 4 describes how silver, which possesses anti-microbial properties, avoids biofouling. Hydrophilic nanomaterials can improve permeability by increasing the hydrophilic nature of the membrane surface. This may prevent bacterial growth on membrane surfaces, so ensuring membranes used in desalinisation and water reuse may be themselves reused. This reduces costs. Chapter 16 explains the concept of nanobubbles, providing a thorough theoretical description of how nanobubbles behave and interesting case studies (e.g. enhancement of aeration mass transfer).
‘Emerging Nanotechnologies for Water Treatment’ is a good read for professionals and academics interested in environmental nanotechnology at early technology readiness levels.
