Hammarby Sjöstadsverk (HSSV) (Sweden)

The facility used for the Swedish demonstration site is the R&D facility Hammarby Sjöstadsverk. It is a platform for development and exchange of knowledge and technologies in water treatment and related environmental technology. It offers the possibility for testing, demonstration and analysis and it is used for collaboration with national and international organisations as well as for education, including degree projects. The activities at Hammarby Sjöstadsverk contribute to the development of more efficient technologies, including the implementation and demonstration of these. Hammarby Sjöstadsverk promotes cooperation among companies, experts/researchers and municipal sewage works to meet future challenges in the water and wastewater sector and to increase the export of Swedish knowledge and technology.

The facility is owned and operated by a consortium led by the Royal Institute of Technology (KTH) and IVL Swedish Environmental Research Institute. It is used for long term national and international research projects as well as consultancy, testing and development for the industry and other partners.

Examples of activities are:
– Basic research and development
– Applied research and development
– Reference and demonstration facility
– Education and platform for knowledge exchange

More details on the Swedish demonstration site are available here.


The main objective is to demonstrate different technologies that support the conversion of a wastewater treatment plant into a resource efficient production facility. Specific objectives are:
– Installations of technologies to be demonstrated at the demo site Hammarby Sjöstadsverk
– To demonstrate technologies in operation and monitor their performance
– To evaluate technologies and provide a platform for dissemination of results by study visits


The following technologies will be demonstrated at HSSV:
– On-line water monitoring (with and without integration of ozonation or chlorination system for disinfection)
– Reducing aeration energy by fluidic oscillation technology
– Increasing methane content in biogas from anaerobic digestion by fluidic oscillation technology
– Innovative control strategies for the Anammox wastewater treatment process
– Removal of priority pollutants by polishing of effluent with adsorbent
– Model based predictive control for resource efficient treatment
