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.

Requirements for sludge sanitisation are something that water and wastewater operations will likely need to address within the next 5–15 years. One proposed option for sanitisation is thermophilic digestion at 55°C, with an exposure time of 8 hours.
Purified and recycled wastewater for industries can be utilized as a resource and contribute to sustainable water use. But when should we implement this, and what are the driving forces?
In both Helsingborg and Lund/Malmö, experiments with decentralized wastewater treatment are underway.
In a four-year frame trial, uptake of phosphorus and heavy metals will be evaluated from two different types of sewage sludge and five different sludge biochars in frame trials.
Testbed Ellinge is a project whose main purpose is to create a basis for the Swedish wastewater works´ choice for sustainable sludge management.
This is Ashley Hall’s doctoral thesis. Ashley is an industrial doctoral student from Sweden Water Research through Lund University.
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.
