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.

The global population is expected to be about 8.2 billion by 2025. This suggests a dire need to prepare for the ongoing and impending challenges linked with water stress to create a water-secure ecosystem. Densely populated countries such as India and China are enhancing the production of semiconductor, petrochemical, automotive, chemical, and pharmaceutical products, which are materially enriching. Simultaneously, our quickly diminishing resources are being further stressed by unprocessed industrial waste. Therefore, to build a sustainable and hygienic livelihood for all, it is imperative to be able to remove conventional and emerging pollutants from water in an affordable and energy-efficient manner. Nanotechnology-based solutions have made substantial contributions towards offering sustainable solutions in the clean water space. Although nanotechnology-based water purification has been an active research area for decades, it is yet to occupy a significant market share because of irregularities in the context of sensitivity, efficient operation in the field, and higher cost in comparison to traditional technologies. This chapter will highlight emerging technologies for drinking water which have also reached society in the form of easily operable devices, such as nanomaterial-incorporated handpumps, desalination devices, and atmospheric water generators.
