Course details

The Wastewater Treatment and Recycling course provides a comprehensive understanding of the principles, processes, and technologies used for the treatment, reuse, and sustainable management of wastewater generated from domestic, industrial, and municipal sources. The course explains how wastewater characteristics influence treatment selection and how treated effluent can be safely reused to reduce freshwater demand and environmental pollution.

The course begins with an overview of wastewater sources, flow estimation, and characterization, including physical, chemical, and biological parameters. Learners study primary, secondary, and tertiary treatment processes in detail, covering physical separation methods, biological treatment systems, and advanced treatment technologies for nutrient and contaminant removal. Emphasis is placed on process design concepts, operational considerations, and performance evaluation of wastewater treatment plants.

The course also addresses sludge treatment and disposal, energy recovery, and emerging technologies for wastewater recycling. Advanced topics such as membrane systems, disinfection methods, and decentralized treatment solutions are discussed in the context of water reuse for agriculture, industry, and urban applications. By the end of the course, learners gain the ability to understand treatment process selection, interpret design and operational data, and support sustainable wastewater management practices.
