Come and visit a platform for research, development and exchange of knowledge and technology in water purification. The facility is national and internationally used by academia, research organisations, companies and WWTPs. Current activities include pilot tests for the implementation of the world largest membrane bioreactor at Stockholm’s main wastewater treatment plant, treatment of micropollutants and pharmaceutical residues, removal of microplastics, reuse of treated wastewater, increase bioenergy production from wastewater etc.

For more information, please visit the webpage of Hammarby Sjöstadsverk or read more in this presentation of the plant.

Tickets can be purchased when registering to the World Water Week.
Cost: 250 SEK
Transportation and refreshments included.


For everyone’s safety, this year, no large bags will be allowed into the venue or at any social events. We encourage all participants to drop luggage at hotels before arriving to the venue. Please be prepared for bag search at the entrance.


09:00     Leaving City Conference Center

              After arrival on site, visitors will be divided in groups that follow
              a guide through the R&D-facility presenting different ongoing
              activities related to innovative treatment technologies of
              sewage water and sludge. Each guide is a professional expert
              working on site and that can therefore provide detailed
              information about process configurations and outlooks.
              Questions can be directed to the guides throughout the tour.
              The tour will cover some of the main ongoing activities


              Preparation trials for the Wolds largest
              MembranBioReaktor for advanced sewage treatment

              Pilot-tests with flat-sheet and hollow-fibre membrane
              technology for upgrading existing urban conventional activated
              sludge processed to MembraneBioReactors (MBR) in order to
              significantly increase treatment capacity, robustness, efficiency
              and enhanced effluent quality. In collaboration with Stockholm
              water company for their reconstruction of the Stockholm
              Henriksdal WWTP.


              Reuse of treated wastewater for non-potable use
              Combining conventional and emerging secondary and tertiary
              treatment techniques in various combinations, optimized from
              an overall sustainability perspective, the ReUse-project
              established a number of treatment systems for different regions
              in the world targeting various effluent qualities for agriculture
              reuse, industrial reuse or groundwater recharge. Reuse of
              wastewater for various reuse purposes without increasing the
              total environmental impact and without increase in costs. In
              collaboration with Xylem Inc.


              Complementary systems for the purification of 
              pharmaceutical residues and other priority persistent

              Tests and further development of the most effective treatment
              options, including oxidation, biological filters, membranes,
              activated carbon, enzymes, their combinations, etc.
              Technologies are evaluated regarding overall environmental
              impact and cost, but also their potential to adapt to new
              developments in the future.

              Demonstration of innovative solutions for Reuse of water, 
              Recovery of valuables and Resource efficiency in urban
              wastewater treatment. An European project.

              Innovative anaerobe system for sewage treatment
              Complete treatment system consisting of 
              UpflowAnaerobicSludgeBlanket (UASB) reactor, mainstream 
              anammox and prosperous removal for maximum resource
              efficiency. Includes some of the world’s most innovative pilot
              tests with long-term (>2 yrs) operation of UASB and
              deammonifikation in the mainstream for normal sewage water
              (combined sewer system).

              Increased biogas production
              Development of different systems and configuration to enhance
              the production of biogas at existing WWTPs with minimum
              investment needs. Further, GHG-emissions reduction from
              sludge treatment is a focus areas at the R&D-facility.

              There will also be representatives of collaborating companies
              on site to support visitors with any commercial inquires.
