Technological Solutions for Water Sustainability: Challenges and Prospects: Towards a Water-secure India
This book provides an overview of technical sustainable water management in the Global South, mainly in India, and is structured in five sections:
The current status and challenges for sustainable water management in India
New-age materials for water and wastewater treatment
New technologies for water and wastewater treatment
Sensors for water quality monitoring
Urban water management
Section 1 provides the latest information about the status and challenges for sustainable water management in India from the perspective of water quality, industrial and domestic wastewater treatment, urban water infrastructure and policy and governance towards water security. Section 2 discusses new framework solids for water purification, new materials for arsenic and fluoride removal, nanocomposites for water and wastewater treatment and removal of hazardous materials, and toxicity of these materials. Section 3 presents the new technologies developed for water and wastewater treatment; dealing with pulsed power technology, constructed wetlands, nutrient recovery, low-cost filters and pollution abatement using waste derived materials. Section 4 focuses on sensors, including the development of low-cost colorimetric sensors for eutrophying ions, sensors for conductivity and flow parameters, and multi-analyte assessment for water quality. Finally, Section 5 addresses the issues related to urban water infrastructure, sustainable urban drainage and integrated flood and water scarcity management.
This section also discusses virtual water.
The unique feature of this edited volume is its special perspective on emerging economies in the Global South, such as India. It provides information about adaption of technologies, development of new technologies, and management practices which are context driven and region specific. It also deals with economical and easy to use sensors for large-scale monitoring of water quality and water quantity parameters.

Porous organic polymers (POPs) have received substantial research attention in the last two decades owing to their modular functionality, tailorable pore size, excellent hydrothermal stability, and high specific surface area. Thus, POPs have emerged as potential adsorbent materials for efficiently removing diverse classes of contaminants ranging from organic micropollutants to heavy metal ions from water. Incorporating guest-responsive supramolecular cavitands and cages into the porous polymers enhances their activity and facilitates the selective scavenging of organic micropollutants from water. On the contrary, crystalline covalent organic framework-based thin films/membranes with precise one-dimensional nanochannels are highly suitable for nanofiltration-based water treatment for the size-selective removal of organic micropollutants and metal salts. In this chapter, we focus our discussion on the various types of emerging amorphous and crystalline POPs for wastewater treatment. Additionally, we will discuss the challenges related to the processability of the materials as well as shed light on some of the future avenues of POPs for the removal of emerging persistent micropollutants from water.
