Phosphorus availability in sludge biochar
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.
Our projects
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.

Testbed Ellinge
Testbed Ellinge is a project whose main purpose is to create a basis for the Swedish wastewater works´ choice for sustainable sludge management.
Treatment of source separated greywater for lower effluent requirements with MBBR and Horizontal Filters
This is Ashley Hall’s doctoral thesis. Ashley is an industrial doctoral student from Sweden Water Research through Lund University.
MACRO – Food in circular robust systems, step 3
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.
The untapped potential of greywater: Decentralised treatment and use for blue-green public spaces
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.
Run4Life – Recovery & utilisation of nutrients 4 low impact fertiliser
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.
Increased production of biogas through industrial symbiosis – co-digestion of steam pretreated straw and sewage sludge
Straw has an untapped potential for domestic biogas production of at least 4.3 TWh.
NPHarvest – Sustainable recycling of phosphorus and nitrogen
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 – for sustainable, job-creating urban development, step 3
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.
Nutrient recycling from wastewater – literature study: an overview of technologies, costs and environmental impact
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.
Sewage sludge spreading on arable land – long-term effects on soil and crops, as well as the presence of antibiotic-resistant bacteria
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.
Sewage sludge spreading on arable land – PFAS in sludge, soil, crop and earthworm
Is the use of municipal sewage sludge on arable land a spreading route for PFAS?
