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.

FramBliK – The future biofilm process, still with continuous operation

Many municipal wastewater treatment plants are facing expansion and reconstruction. Lack of space and requirements for sustainability mean that compact, resource-efficient, environmentally friendly and cost-effective solutions are in demand. This project is about investigating a new biofilm process, with a bio-based carrier, to assess whether this process can be a viable alternative in future wastewater treatment plants.

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.

AGNES – Aerobic Granular sludge – Nutrient removal and recovery Efficiency in Sweden

More stringent discharge limits and increased load due to population growth and centralisation create needs of upgrading and enlarging the existing municipal wastewater treatment plants (WWTPs). Also expansion of housing areas close to the treatment plants increase the demands of retrofits and upgrades that are space efficient. At the same time we want the treatment methods to be robust, energy, carbon and chemical efficient, have low carbon footprint and facilitate recovery of plant nutrients.

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.

LaGas

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.
