Shortcut nitrification in activated sludge process treating domestic wastewater - key technology for low-carbon and clean wastewater treatment

About this project

<p>The aim of this Project is to create an innovative Technology that will allow to achieve mainstream shortcut nitrification/denitrification via nitrite at municipal wastewater treatment plants (WWTPs). Achieving this objective will significantly reduce oxygen and organic carbon demand for nitrogen removal process, improve effluent quality and increase digester gas production. This Technology also includes a development of separate reactor for sludge disintegration with nitrous acid to aim easy biodegradable organic carbon for denitrification process improvement, which is usually limited by organic carbon available in raw wastewater. This Technology will therefore lead to lower energy consuption, better effluent quality and lower greenhouse gas emission. Those goals are perfectly suited in nowadays needs and EU policies. This project will benefit operators of wastewater treatment plants as well as scientific community by deepening our understanding of wastewater treatment biological processes and developing technology for better and less expensive wastewater treatment.</p>

Bilateral cooperation results

The project greatly benefited from having a Norwegian partner. Partner provided essential expertise and resources that were crucial for the project's success especially in the sector of sludge management. There was a significant exchange of knowledge and skills, enhancing the capabilities of all parties involved. Therefore, the collaboration fostered innovative approaches and solutions to the project's challenges and led to significant advancements in the objectives. The collaboration resulted in co-authored publications, disseminating the findings to a wider audience showcasing the project's achievements. Moreover, the collaboration enhanced technical skills and understanding among team members. Organized during project duration project meetings and common events also promoted cultural exchange and mutual understanding, enriching the working environment and fostering better teamwork. The partnership led to the adoption of improved methodologies and best practices from both countries. Results: - The bilateral collaboration led to improved project outcomes,. - Partners experienced significant capacity building, and gaining experience in new rese techniques. - The partnership emphasized sustainable practices not only in relation to technical issues but also project management itself, which were integrated into the project framework. - The project intent to influence policy-making processes, particularly in areas related to the use of renewable energy profitable wastes. - The collaboration had a positive impact on young researchers taking part in the project or supporting it at any level. It boosted their knowledge and was opportunity to experience the work in international team. There are plans to continue the collaboration in future projects, building on the successful partnership. Potential joint ventures are being explored.
