WATER containing unwanted substances which adversely
affect its quality and thus making it unsuitable for use is
termed as wastewater. Wastewater is generated from various
sources such as residential areas, commercial/industrial
properties, agriculture etc. Composition of wastewater varies
widely and depends upon the source from which it is
generated. Common constituents of wastewater are
pathogenic and non-pathogenic microorganisms, organic
substances such as excreta, plants material, food, protein, and
inorganic substances like metal particles, ammonia along with
gases. When left untreated these constituents may pose threat
to living beings and the environment, which makes it essential
to treat wastewater before disposal. Various physical,
chemical and biological treatment processes are used for
wastewater treatment. Among these methods, currently,
nanotechnology has been extensively studied by researchers as
it offers potential advantages like low cost, reuse and
