Sweden Water Research conducts research into water and develops new, effective solutions to meet the future challenges facing the water services industry.
We create, run, participate in and initiate projects that seek out suitable partnerships, with the ultimate aim of increasing knowledge of successful methods for the development and climate change adaptation of the cities of the future. Projects within Sweden Water Research are run in close collaboration with the owner municipalities and will, in either the short or the long term, benefit day-to-day operations.

Approximately half of the micropollutants in municipal wastewater are removed in wastewater treatment plants (WWTPs) through adsorption or biological degradation. However, the knowledge about this removal is inadequate.
Testbed Ellinge is a project whose main purpose is to create a basis for the Swedish wastewater works´ choice for sustainable sludge management.
Source separated wastewater systems enable a circular economy through the return of plant nutrients, reduced water use, reduced energy use, increased biogas production and reduced greenhouse gas emissions.
Sweden also has a water shortage some summers. In 2018, more than 80 municipalities needed to introduce restrictions on water use. With source-sorting sewage technology, the possibility of using greywater for irrigating green areas is opened up.
The world food supply is entirely dependent on the use of fertilisers. However, the current fertiliser production practices are not sustainable. Domestic wastewater is an important carrier of resources: especially water, energy and nutrients. In the current centralised wastewater management systems these resources are hardly recovered.
Straw has an untapped potential for domestic biogas production of at least 4.3 TWh.
NPHarvest is a technology, developed by Aalto University, to extract phosphorus and nitrogen from highly concentrated wastewater streams such as digested black water or reject water from the digestion of sewage sludge. The technology has been tested on a pilot scale at RecoLab.
Cultivating urban bazaars is an innovation project whose goal is to build a small-scale, sustainable industry through urban cultivation that creates new jobs and the opportunity to reach out to start-up companies focused on innovative environmental technology.
IVL Swedish Environmental Institute, together with a number of project partners and through financial support from, among others, Swedish Water & Wastewater Association, has carried out a review of methods for recycling nitrogen, sulphur and potassium from wastewater.
In 1981, field trials were started to investigate the short- and long-term effects of the spread of municipal sewage sludge on arable land. Initially, there were five test fields, but for a long time the project has been concentrated on two of them: Igelösa outside Lund, which receives sludge from the Källby Wastewater Treatment Plant (WWTP), and Petersborg outside Malmö, which receives sludge from the Sjölunda WWTP. The project has so far had nine stages of four years each. The period 2018-2021 will be the tenth stage of the project.
Is the use of municipal sewage sludge on arable land a spreading route for PFAS?
