The establishment of clean, safe water is one of the major
challenges facing societies around the globe. The continued
urbanization of human populations, the increasing manipulation of
natural resources, and the resulting pollution are driving
remarkable burden on water resources. Increasing demands for food,
energy, and natural resources are expected to continue to
accelerate in the near future in response to the demands of these
changing human populations. In addition, the complexity of human
activities is leading to a diversity of new chemical contaminants
in the environment that represent a major concern for water
managers. This will create increased pressure on both water
quantity and quality, making it increasingly difficult to provide a
sustainable supply of water for human welfare and activities.
Although protection of water resources is the best long-term
solution, we will also need innovative novel approaches and
technologies to water treatment to ensure an adequate superior
quality resource to meet these needs. Solving tomorrow's water
issues will require unique approaches that incorporate emerging new
technologies. Great advances have been made in the area of
nanotechnology. Due to their unique physical and chemical
properties, nanomaterials are extensively used in antibacterial
medical products, membrane filters, electronics, catalysts, and
biosensors. Nanoparticles can have distinctly different properties
from their bulk counterparts, creating the opportunity for new
materials with a diversity of applications. Recent developments
related to water treatment include the potential use of carbon
nanotubes, nanocompositae, nanospheres, nanofibers, and nanowires
for the removal of a diversity of chemical pollutants. By
exploiting the assets and structure of these new materials, such as
increased surface area, high reactivity, and photocatalytic action,
it will be possible to create technologies that can be very
efficient at removing and degrading environmental pollutants.
Understanding and using these unique properties should lead to
innovative, cost-effective applications for addressing the
complexities of emerging needs for water treatment and protection.
Although still in the early stages, research into the application
of nanotechnology shows great promise for solving some of these
major global water issues. This comprehensive text describes the
latest research and application methods in this rapidly advancing
field.
This book provides an overview of recent advances in technologies
for water treatment processes, such as green technology,
nano-adsorbents, photocatalysts, advanced oxidation, membranes
separation and sustainable technologies. Advances in membrane
technology and fabrication process is presented in detail. Latest
approaches like microbial treatment, electro chemical and solar
energy-based treatment techniques were presented. Also, the use of
sustainable and energy efficient approaches were discussed.* The
book presents the negative impact of inorganic and organic
pollutants on the natural environment and human health. It
describes and discussing the advanced membrane technologies, novel
green adsorbents, microbial treatment techniques, electro chemical
and solar based removal techniques It also compares the most
effective methods of removing toxic contaminants from water
solutions with the use of sustainable and energy efficient
approaches It also presents the life cycle assessment of emerging
technologies in industrial wastewater treatment and desalination as
well as presents the benchmarking of energy efficiency during
treatment process
