This course introduces biological principles used in the design and operation of biological wastewater treatment plants. Water scarcity is one of the most critical challenges in human society. Billions of people in the world have poor access to clean water and such a situation is getting worse with rapid population growth and industrial development.

Wastewater treatment is an important approach to recover valuable water and reduce its pollution to the environment and risks to humans. Biological wastewater treatment is a cost-effective and most used technique for wastewater treatment.
This course introduces the fundamental design principles and practice of biological wastewater treatment and prepares students for designing wastewater treatment systems. At the end of the course, students are expected to understand general biological principles and design practices of wastewater treatment, apply the knowledge to select the best unit process to treat wastewater, and design a wastewater treatment component or process to meet water quality treatment goals.
This course is part of the Water and Wastewater Treatment MicroMasters.
