Pollution due to various anthropogenic activities continues to
increase. In terms of water pollutants, organic and inorganic
pollutants are the most problematic. Although several measures have
been proposed and implemented to prevent or reduce contamination,
their increased concentration in water bodies has created serious
concerns. Over the years, the problem has been aggravated by
industrialization, urbanization and the exploitation of natural
resources. The direct discharge of wastewater contaminants and
their geographical mobilization have caused an increase in
concentration in ground, surface, fluvial and residual waters.
Extensive information about detection and disposal methods is
needed in order to develop technological solutions for a -variety
of environments, both urban and rural. This book provides
up-to-date information on wastewater contaminants, aimed at
researchers, engineers and technologists working in this field.
Conventional physicochemical techniques used to remove contaminants
from wastewater include ion exchange, precipitation, degradation,
coagulation, coating, membrane processes and adsorption. However,
these applications have technological and economic limitations, and
involve the release of large amounts of chemical reagents and
by-products that are themselves difficult to remove. Biosorption -
the use of organically generated material as an adsorbent - is
attracting new research and scholarship. Thermally-treated calcined
biomaterials may be treated to remove heavy metals from wastewater.
To ensure the elimination of these contaminants, existing solutions
must be integrated with intelligent biosorption functions.
Biosorption for Wastewater Contaminants will find an appreciative
audience among academics and postgraduates working in the fields of
environmental biotechnology, environmental engineering, wastewater
treatment technology and environmental chemistry.
