The Treatment of Wastewater, Recycling and Reuse - Past, Present, and in the Future
Jyotsana Maura | Suchita Atreya | Anfal Arshi
Abstract: A thorough analysis of wastewater treatment, recycling, and reuse options has become necessary due to the global issues faced by water scarcity and environmental deterioration. This book chapter focuses primarily on the recycling and reuse of treated wastewater as it covers the development of wastewater management practices from historical approaches to present developments and future prospects. The first section delves into historical background, describing early wastewater disposal techniques and how their negative effects on ecosystems and public health were later realized. It draws attention to the development of traditional wastewater treatment methods like primary and secondary treatment, which sought to lessen the negative consequences of wastewater discharge. The chapter also covers the development of tertiary treatment methods, such as sophisticated filtration, chemical precipitation, and membrane technologies, which allowed for a greater degree of pollutant removal and prepared the way for effective recycling and reuse systems. It addresses modern strategies such as centralized and decentralized treatment systems, noting their benefits and drawbacks. Additionally, it covers the significance of technological developments in improving treatment effectiveness and water quality for safe reuse, such as enhanced oxidation processes, membrane bioreactors, and artificial wetlands. The chapter also highlights the significance of strict laws and frameworks for policy in supporting wastewater recycling and reuses practices all over the world. The final section explores the possibilities for future development in wastewater treatment, recycling, and reuse. It talks about new trends like resource recovery, energy-neutral treatment methods, and the incorporation of smart technology and artificial intelligence in wastewater management systems. It also points into more detail on the advantages of decentralized and naturally based approaches to establishing resilient and sustainable water management practices. This book chapter offers a thorough overview of practices for wastewater treatment, recycling, and reuse, traces their development from the past to the present, and offers predictions for the future.
