Resource efficient wastewater systems

In this research field we work with small on-site wastewater systems as well as with the municipal wastewater system and its centralisation/decentralisation.

Microplastics course and workshop in Oulu - Finland

From 3 to 5th December, the PhD students Katharina Lange and Brenda Vidal, Stormwater&Sewers/Luleå University of Technology, participated in a workshop and course about microplastics titled “Development and challenges related to sampling, analysis, removal and environmental impact assessment of micr...

New report on the formation of sludge and the composition of biofilm in wastewater drain fields

The most common methods for on-site treatment of domestic wastewater are soil-based methods such as drainfields. In previous municipal projects, the occurrence of sludge in different parts of such treatment facilities has been observed.

In the media: World Toilet Day was highlighted in Norrtälje

Brenda Vidal, from Luleå University of Technology, talked about her study “Small Flexible Sewage Solutions: Adapting to a Changing World” which is a multi-criteria analysis where different types of small sewerage systems have been set in relation to different sustainability criteria and scenarios.

Small on-site sanitation systems - how sustainable are they?

Small on-site sanitation systems emit wastewater locally, which is why it is important that the systems meet the requirements for the release of organic material and nutrients and also meet the requirements for infection protection. Often, unfortunately, the small systems do not work as they should,...

The Annual Academic Ceremony 2019

On Saturday 9th of November, the annual graduation ceremony took place at Luleå University of Technology. Urban Water Engineering was represented by two people.

Study on nutrient recovery from urine to agriculture in Northern Sweden

In the North of Sweden, nutrient recovery from wastewater fractions is still not practised. In this study, we assessed the potential of reuse of nutrients from urine to agriculture in theNorth of Sweden in terms of quantity and environmental impact of collecting, treating and spreading urine-based f...

Improved sanitation systems in rural areas

In large areas of northern Scandinavia on-site sanitation systems are used. In a new project investigates the function of existing treatment systems, their effect on the environment, how the treatment efficiency can be increased and which alternative systems can be used.

Sustainability and treatment efficiency of on-site sanitation systems

The PhD student Brenda Vidal presented her Licentiate thesis on December the 19th with the title “On-site Sanitation Systems – An Integrated Assessment of Treatment Efficiency and Sustainability”.

Urban Water PhD students visiting INSA in Lyon

Two of LTU PhD students visited INSA in Lyon, France to study methods for multicriteria analyzes and green roof solutions.

In the media: Microflora in wastewater is investigated

Kungsbacka project "Microflora in soil-based treatment plants" in cooperation with Luleå University of Technology.

New report about on-site wastewater treatment

This report summarises the results from the projects "Phosphorus filters for on-site wastewater treatment - how long do they work?" (1236-15) and "Discharge of bacteria from on-site wastewater treatment units" (1240-15) that were funded by the Swedish Agency for Marine and Water Management (fund 1:1...

Small flexible urban water systems

When Sweden and Europe is changing due to climate change and urbanization our aging systems for urban water infrastructure must be updated. Researchers at Luleå University of Technology investigate small flexible urban sanitation solutions compared to today's centralized sewage systems in the indust...

In the media: Municipalities in a research project on small sewages

Luleå University of Technology has also received funding for another project, bacterial emissions from small sewages.

Lower emissions from small sewage

Small-scale drainage system for water emit large amounts of phosphorus causing eutrophication. The PhD student Inga Herrmann, Luleå University of Technology, develops methods that facilitate the production of effective filters for phosphorus removal.
