Advanced Materials for Wastewater Treatment / Edition 1

by Shahid Ul Islam

Overview

This comprehensive book deals with the use of novel materials such as plant-derived agents and advanced nanocomposites for the removal of heavy metals, nitrates, and synthetic dyes.

Water is an essential component for living organisms on planet earth and its pollution is one of the critical global environmental issues today. The influx of significant quantities of organic and inorganic waste, sediments, surfactants, synthetic dyes, sewage, and heavy metals into all types of water bodies has been increasing substantially over the past century due to rapid industrialization, population growth, agricultural activities, and other geological and environmental changes. These pollutants are very dangerous and are posing serious threat to us all.

Advanced Materials for Wastewater Treatment brings together innovative methodologies and research strategies to remove toxic effluents from wastewaters. With contributions from leading scientists from all around the world, the book provides a comprehensive coverage of the current literature, up-to-date overviews of all aspects of toxic chemical remediation including the role of nanomaterials. Together they showcase in a very lucid manner an array of technologies that complement the traditional as well as advanced treatment practices of textile effluents. In particular, the book provides:

• Up-to-date overviews of all aspects of toxic chemical remediation
• The role of plants and abundantly available agro-wastes in the remediation of wastewater
• The removal of nitrates from wastewater using nanocomposites
