In this chapter, we have made an overview of the whole book and
summarized the environmental pollutions and their treatment with new materials and
technology. We highlighted how to resolve the old challenges with new solutions. We
reviewed different methods used for environmental remediation and highlighted the
importance of nanomaterials in environmental remediation. Different processes related
to the management of waste water polluted by bacteria, organic, inorganic pollutants,
and toxic metal ions, etc. have been discussed. We discussed how nanomaterials are
economical solutions for the resolution of the old challenges related to waste water
treatment. We also deliberated that the waste water containing harmful metal ions,
organic pollutants, bacteria etc. can be treated with nanomaterials and for this purpose,
development of novel nanomaterials is paramount because nanomaterials have
revolutionized the scenario of emerging catalytic and adsorption technologies with
recently certified efficient removal of pollutants along with the low cost and high
stability. Therefore, the molecular engineering of nanomaterials to use them to reach
stable state-of-the-art efficiency for the removal of pollutants as adsorbent and catalysts
is vital and the high efficiency coupled with low cost and easy treatment process of the
developed nanomaterials has probability to compete and replace the established
technologies.
