From Wastewater Treatment to Water Resource Recovery

In preparation for the IWA World Water Congress & Exhibition in Copenhagen in September, Unisense Environment are hosting a webinar to learn about the most recent developments in sustainable wastewater treatment.

We are delighted to welcome three guest speakers at the webinar Working towards Net Zero on 7 September at 3.00-4.30 pm (CET):

  1. Anders Lynggaard-Jensen, Chief Engineer Automation and Process Optimization at Aarhus Vand
  2. Maria Faragò, PhD Fellow at Technical University of Denmark
  3. Dines Thornberg, Head of R&D at BIOFOS

You can learn more about our speakers below.

Sustainable Wastewater Treatment

Wastewater treatment plants across the world are taking steps to reduce their climate footprint. If you get the chance to join the IWA World Water Congress, you can visit the 400,000 PE Avedøre wastewater treatment plant. The plant has gone one step further with the transformation into a Water Resource Recovery Facility. A project that both BIOFOS and Unisense Environment have been closely involved in. You can learn more about the project at projekt-varga.dk, and you can learn more about the details in this scientific article: From wastewater treatment to water resource recovery: Environmental and economic impacts of full-scale implementation.

Dines will touch upon this project in his presentation. If you join the technical tour of the plant during the IWA Congress, you can also meet our Sales Engineer Bastian Piltz on-site. He will tell you how the plant works with nitrous oxide minimisation by online control.

Working towards Net Zero 1

Program: Working towards Net Zero

  1. Anders Lynggaard-Jensen: Calibration and Validation of Real time Calculation of the N2O Emission from Activated Sludge Tanks
  2. Maria Faragò: The role of N2O emissions in the life cycle assessment of a water resource recovery facility in Copenhagen.
  3. Dines Thornberg: Evaluation of Greenhouse Gas Emissions from Wastewater Treatment in EU
  4. Panel discussion

Calibration and Validation of Real time Calculation of the N2O Emission from Activated Sludge Tanks

Anders Lynggaard-Jensen's presentation describes the calibration of a software sensor calculating the N2O emission from aeration flow, temperature, and dissolved N2O using a hood, which measures off-gas flow and N2O. Furthermore, Anders will describe the setup and procedure together with the challenges and pitfalls.

The role of N2O emissions in the life cycle assessment of a water resource recovery facility in Copenhagen

Maria Faragò will illustrate the results of implementing real-time monitoring and control in a forthcoming water resource recovery facility in Copenhagen in light of a life cycle assessment. She will also explain the role of holistic assessments in evaluating how close a treatment plant is to achieving climate neutrality.

Evaluation of Greenhouse Gas Emissions from Wastewater Treatment in EU

Dines Thornberg will present an assessment of greenhouse gas emissions from urban wastewater treatment plants in Europe. The assessment will include all phases of wastewater treatment, from the construction of the infrastructure to the discharge of treated effluents. He will also present various scenarios to reduce emissions.

Anders Lynggaard-Jensen

Anders is Chief Engineer Automation and Process Optimization at Aarhus Vand.

Among other things, Anders is responsible for the design and implementation of integrated control of the water supply, from source to tap. He has close to 40 years' experience working with instrumentation, control and automation related to water and wastewater. His work has included the development of sensors, software for real time data processing, and control algorithms. His focus has been on process optimization on wastewater treatment plants incl. biological nitrogen and phosphorous removal, clarifier hydraulics, and integrated control of combined sewer systems and wastewater treatment plants during rain.

Maria Faragò

Maria Faragò is a PhD Fellow in Environmental Engineering at the Technical University of Denmark.

Her PhD thesis focuses on eco-efficiency assessment of water and wastewater resource recovery facilities in collaboration with the Danish water utilities BIOFOS, Aarhus Vand and VandCenter Syd. Maria has followed the transformation of the Avedøre Wastewater Treatment Plant into a Water Resource Recovery Facility in detail. You can look forward to learning from her research and experience.

Dines Thornberg

Dines Thornberg is Head of R&D at BIOFOS. He has studied and worked with wastewater for close to 40 years.

BIOFOS operates 3 wastewater treatment plants, which serve around 1.2 million people in and around Copenhagen. Dines works with the development and implementation of new processes and methods. The key focus is that new operations need to make sense from an environmental as well as a business angle.
