New paradigms in wastewater management: from a sanitation problem to a circular sustainable solution

The new paradigms in the management of the urban water service: originally conceived to protect public health through safe water supply and adequate treatment of wastewater, current trends aim not only at process optimization and energy savings but also at energy and material recovery from wastewater and sludge.

Introduction to the sustainability series

This MOOC is part of the series on “Sustainability”, which is one of the world’s major challenges of today and tomorrow and requires multidisciplinary competences. The series provides technical knowledge on a variety of topics, such as sustainable building, energy transition, water management and food waste prevention.

Course description

The water cycle is strictly related to the fair and sustainable development of any society. Appropriate technologies and practices are needed for providing clean water and adequate sanitation to citizens worldwide, while facing environmental and societal challenges, such as climate change and increasing urbanization. Wastewater treatment facilities are nowadays shifting from infrastructures providing effective clean water, sanitation and environmental protection towards advanced biorefineries that can recover valuable resources (as reusable water, biopolymers and nutrients) from wastewater, while aiming at more stringent effluent quality targets, at energy neutrality, and at lowering the overall environmental impact. This MOOC is aimed at providing key elements in relation to the management of the urban water cycle, including both conventional goals and the challenges of the smart cities of the future. This MOOC presents a full picture, although very concise, of present and emerging technologies for wastewater treatment, presented by professors teaching at Politecnico di Milano.

Total workload of the course: 8 hours

This MOOC is provided by Politecnico di Milano.
