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…
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.
