An unprecedented increase in urbanization and industrialization ignited by
an upsurge in the development of consumer goods. This has been steadily destroying
the environmental balance and ecosystem and diminishing the water quality.
Inevitably, we are facing one of the biggest challenges of the time, which needs to be
resolved with proper remediation strategies to provide clean water as one of the
essential components for human beings and agriculture, livestock, and several
industrial survivals. With the growing demand for water and sustainable improvement,
utilizing unconventional water supplies such as contaminated fresh water, brackish
water, and wastewater is required. Although some of the traditional water treatment
and purification methods still retain their importance. However, there is a need to
provide faster and more efficient technologies beyond conventional methods for
treating various contaminated water sources, including emerging pollutants. Recently,
catalytic processes such as ozonation and electrocatalysis, including electrocatalytic
oxidation, electro-Fenton process, photo electro-Fenton process, photocatalysis, and
reduction by hydrodehalogenation, exhibited unique features and have opened wide
opportunities in the field of water treatment. This chapter describes various types of emerging contaminants, their effect on human health and the ecosystem, and analytical
methods of ECs quantification. Moreover, the features, mechanisms, and potential
applications of catalytic processes in treating emerging pollutants are discussed in
detail.
