Innovations in Carbon Storage and Optimization in Biological Processes

IWA Carbon-redirection; internal carbon management; enhanced biological phosphorus removal; biological nutrient removal; short-cut nitrogen removal

Target Audience

Professionals, industry, academia, and other relevant stakeholders in the water sector.


Integrated source-watershed management, containment, treatment, and recovery strategies are needed to mitigate the environmental impacts associated with Phosphorus (P) flow through various processes and environmental compartments. Holistic thinking requires that the associated carbon footprints with various integrated interventions be taken into account. Challenges remain in advancing sustainability in nutrient removal, with the need to identify knowledge gaps in developing and implementing nutrient removal processes that allow carbon-usage optimization and decarbonization.

This webinar will present new concepts and strategies in developing and implementing nutrient removal processes, including enhanced biological phosphorus removal (EBPR) and short-cut nitrogen removal processes, leveraging the internal carbon storage and allowing carbon usage optimization. These innovative processes can overcome some of the main limitations and enable simultaneous, coupled EBPR and short-cut nitrogen (N) removal.

In the meantime, nutrient recovery from wastewater is providing a sustainable path. As the paradigm includes circular carbon and nutrient approaches, new research and practice are needed to discover innovative technologies that make up such circular approaches. This webinar will also extend EBPR to P recovery process and attempt to inspire novel ideas for wastewater treatment processes.

This webinar will be dedicated to Prof. David Stensel (1945-2021), University of Washington, USA, who truly was a fount of knowledge in the field and had a lifelong passion for returning clean water to the environment through biological processes.
