Water is a vital resource for various sectors, but poor management can lead to higher operational costs and regulatory risks. The global water shortage is currently affecting over 2 billion people, and this shortage has increased demand for effective water management. Industries are developing innovative methods for waste treatment, including biological treatment and water recycling. Artificial intelligence (AI) models are being used to optimize the dosage of photocatalysts for wastewater treatment, achieving a 30–40% reduction in water use and higher efficiency in pollutant removal. AI systems can also predict potential environmental damage and hazards, allowing industries to take preventive measures. Smart sensors and Internet of Things (IoT) devices are improving real-time tracking of water quality and usage across manufacturing processes. This chapter explores the latest advancements in wastewater management through advanced technologies such as deep learning, machine learning, and the Internet of Things (IoT). This technological integration results in enhanced and efficient wastewater management systems.
