The aerobic granular sludge (AGS) technology is an innovative, compact and energy efficient wastewater treatment process that seems to be mature for full-scale implementation around the world.
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.
AGNES – Aerobic Granular sludge
Back to the basics: high-loaded activated sludge
Without the presence of enhanced nitrogen removal processes, it is possible to decrease the solids retention time for the organics, including the microorganisms. Therefore is…
Digital twin for sustainable and resource efficient operation of wastewater treatment plants
Within this project, a method for developing digital twins at WWTPs will be developed, including real time process simulation and data validation.
The Intergovernmental Panel on Climate Change (IPCC) highlights wastewater treatment as a significant point source of nitrous oxide emissions. Today, nitrous oxide is also the…
Measurement of direct greenhouse gas emissions from wastewater treatment basins
Climate neutrality in the water and wastewater business can only be fulfilled if emissions of methane and nitrous oxide are low. We need good methods to identify and quantify these emissions.
The Warm and Clean City
Two concepts for wastewater treatment have been produced in the initial project, which will be tested and evaluated: ”energy-positive treatment” and “compact treatment”. A system…
