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.

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?
Pyrolysis of dried sewage sludge generates a sludge biochar that can be used in several applications. VA SYD participates in the project Residues to best use to increase its knowledge about biochar and its possibilities.
Seven water and wastewater service organisations, together with two research institutes, have evaluated the conditions for opening up municipally owned wastewater treatment plants to test techniques for recovering nutrients from wastewater streams.
REWAISE is one of five innovation projects supported by the Horizon 2020 framework program. The goal is to reduce the use of drinking water and use water in a smarter and more efficient way.
Can heat recovery be implemented on a large scale without unacceptable impact on the wastewater system and the environment?
The conventional municipal wastewater systems recover only a small part of the plant nutrients found in the wastewater to farmland. The purpose of the project is to gather important stakeholders in the flow of nutrients from the households to farmland to assess the potential and, hopefully, further develop a urine separation system that has been developed by SLU.
The urine separation systems of the future will include volume reduction to further decrease transport and storage needs and to obtain a more concentrated fertiliser. Stabilisation of the urine is required to not lose the nitrogen through ammonia volatilization during the volume reduction treatment. Nitrification is a promising method for stabilising urine.
