Milestone at Damhusåen Water Treatment Plant with Thermal Hydrolysis Plant (THP)

A wealth of innovation and collaboration is flowing through our ongoing project at Damhusåen Water Treatment Plant, where Aquagain is a key player in the implementation of a thermal hydrolysis plant (THP) as part of Biofos's ambitious development plans.

 

Innovative Digester Tank Renovation with THP Technology
Biofos, a leading player in sustainable wastewater management, has taken a proactive approach to meeting future needs. As part of its digester tank renovation strategy, the company is investing in THP technology, which will reduce residence time in the digester tanks without compromising biogas yield. This will allow the tanks to be refurbished one at a time, which is essential for maintaining stable operations and meeting regulatory requirements regarding treatment quality.

 

Partnership and Collaboration
Cambi, a recognised supplier of THP systems, is the main contractor on this exciting project. Meanwhile, Aquagain has taken on the role of welding contractor and is responsible for all pipe and steel work, as well as the installation of major components.

From the start, the project has been marked by a very high intensity, a focus on progress, changing plans, and tight deadlines. This places high demands on the team's adaptability and the project manager's ability to make big decisions quickly and continuously.

There are large amounts of pipework and components to be installed on this project, both of which require extra attention to detail. Our project manager and supervisor have worked together to create a special system to prevent confusion and ensure that piping systems are installed with the correct components.

 

Broadly speaking, there is close interaction between the various groups of professionals at Aquagain. Despite the high intensity that has marked this project from its very beginning, it has been handled in the best possible way, with the design office, manufacturing, assembly, and project manager all in constant collaboration. Each group is part of a common team that shares a common goal of completing the job to the customer's full satisfaction.

Our talented technical designer, Anne-Sofie—who recently graduated with honours—is a member of the team on this project. We were all proud to hear that she has received special praise from the main contractor for her good Danish design and initiative.

Collaboration is important beyond the confines of our own organisation, too: our close co-operation and open communication with both Biofos and Cambi has been crucial to the smooth execution of the project.

 

Future-proofing, greener energy and a sustainable future
Not only will the renovation of the Damhusåen Water Treatment Plant significantly increase its capacity to treat wastewater, but it will also contribute to the production of green biogas through thermal hydrolysis. This is an important step towards a circular economy and a greener future for the greater Copenhagen area.

Biofos's expansion plan will play a crucial role in ensuring that greater Copenhagen can handle increasing population growth and increased demands for wastewater treatment through to 2045. By increasing the treatment capacity at the Damhusåen and Lynetten treatment plants, we are working together towards a more sustainable and future-proof solution.
