Testbed for industrial water treatment at Hammarby Sjöstadsverket

Reference number

Funding from Vinnova SEK 4 622 500
Project duration December 2015 - March 2019
Status Ongoing

Purpose and goal

The test bed for industrial water treatment has already begun to contribute to environmental benefits in several ways, not least the conversion to a circular economy where both water and process chemicals must start to be recycled. At the same time, emissions of toxic and eutrophic substances to surrounding recipients are also reduced, and higher energy efficiency can be achieved in the processes, In addition to the environmental benefits, the test bed increases the possibilities for new business in the industry.

Expected results and effects

In the EU project Inspirewater which IVL coordinates and which was possible to implement as a direct consequence of this test bed project, we expect to be able to save about 20% energy, recycle about 60% of the process chemicals while at the same time reducing the waste amounts significantly and reducing water consumption by 60%. These are figures that we estimate are possible to achieve in several of the applications that the test bed is and will be involved in, especially in regions with increasing water shortage.

Planned approach and implementation

Together with end users, academic partners and suppliers, the project has broadened the range of equipment at Hammarby Sjöstadsverk (HS). The advanced separation technology equipment for water treatment has been important in broadening the customer base from largely municipal water purification only to now also include advanced industrial process internal water treatment for the recovery of both water and process chemicals and places HS at the forefront in the EU in this segment.
