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.

Characterisation of municipal wastewater

Major investments will be required in the next few years to deal with aging infrastructure, population growth, urbanisation and new emission requirements at municipal wastewater treatment plants (WWTPs). These investments are preceded by evaluation, design and optimization, which in turn require access to good data to provide security in the decisions made and to ensure cost-effective solutions.

Back to the basics: high-loaded activated sludge

Degradation of organic substances in municipal wastewater is conventionally performed in the activated sludge process in presence of enhanced nitrogen removal processes. In the future, new nitrogen removal processes could demand a wastewater already treated for organics. The project "Back to the basics: high-loaded activated sludge" aims to make the high-loaded activated sludge process more efficient.


Emissions of the very potent greenhouse gas nitrous oxide contribute often very much to the sum of greenhouse gas emissions from wastewater treatment with enhanced biological nitrogen removal. The Danish project LaGas aims to identify, implement and validate new control strategies to mitigate nitrous oxide emissions in wastewater treatment.

The Warm and Clean City

Wastewater treatment is an important function of society, and one that confronts many challenges. The project, “The Warm and Clean City” is developing and testing new total solutions for the world’s wastewater treatment plants. The solutions are resource-efficient and facilitate utilizing substances in the wastewater for generating saleable products, while at the same time closing the water and nutrient loops.
