A Zero Liquid Discharge System (ZLDS) is a process that recovers water and solvents from wastewater. The remaining constituents are dehydrated to form pure water, resulting in zero waste. This book is a unique research-oriented guide covering the entire zero-liquid discharge process, from its introduction to its application. Zero liquid discharge water treatment plants require high engineering expertise and careful planning to achieve zero shots. Although it is an efficient wastewater treatment technique, improper industrial wastewater disposal can lead to environmental hazards such as water and soil pollution. This book focuses on ecological degradation and delves deeply into the consequences of improper industrial wastewater disposal, highlighting its effects on water pollution, ecosystem imbalance, and risks to human health. It offers a detailed examination of the resulting contamination and its far-reaching implications, emphasizing the need for proper disposal methods. One of the most critical needs for a healthy life is to provide healthy water and contaminants to be taken from the public water supplies. The book may reflect the healthy situation in many by presenting best practices, aiming to foster an understanding of the role of chemical contaminants in water systems in mitigating environmental hazards and the application of 'zero liquid discharge technology' in detail. As industrial pollution continues to rise, there is a need to explore practical ways of managing industrial residues from wastewater. This book presents innovative research on using a 'zero liquid discharge system' to achieve this locally and internationally. It also examines appropriate resource management strategies to address environmental concerns. This book critically reviews the health effects of industrial chemicals in the water supply. It examines current frameworks’ limitations, challenges, and opportunities and discusses the benefits of using a 'zero liquid discharge system' and their impact on global sustainability. The book also emphasizes this technology to limit toxic industrial material utilization. This chapter provides an overview of the occurrence of industrial chemicals in drinking water and the associated human health risks. This book also analyzes existing policies related to industrial wastewater and proposes policy recommendations for effective wastewater management using a zero-liquid discharge system. It discusses implementation strategies and policy adoption, emphasizing the role of policy in shaping and improving industrial wastewater management frameworks. The edited volume aims to highlight the critical operating factors and consider the large capital investments of this system and the operational costs. However, in this research-oriented book, the readers will clearly understand that this novel system can leave behind a dry sludge containing high concentrations of hazardous chemicals and heavy metals. This edited volume will show that the application of a Zero Liquid Discharge System (ZLDS) requires careful planning and analysis.
