Conferences
Presented topics at international conferences in the field of water and wastewater engineering.
Wastewater treatment technologies
The group focuses on sustainable wastewater treatment. Valuable resources must be reused safely while committing to climate change mitigation. Aalto Donation Professorship 2018 – 2028.
Aalto Donation Professorship 2018 – 2028
The Donation professorship's field is wastewater treatment, and it is funded by several Finnish water utilities, associations, and foundations working in the water sector. The work started in 2018 with Prof. Anna Mikola in the Department of Built Environment at Aalto University. In April 2023, Henri Haimi was appointed a part-time Professor of Practice.
Research themes
Our research themes are resource recovery, removal of micropollutants, and energy and GHG optimization – all this in wastewater treatment and especially in cold climate conditions.
Resource recovery
The role of wastewater treatment is moving from the removal of substances to the recycling of resources.
Emerging pollutant management
The load of different pollutants in the Baltic Sea is a problem we need to solve.
Climate impact of WWTP
Wastewater treatment plants are among the big energy consumers in our societies and they have a significant carbon footprint.
Processes at cold temperature
In Finland and in the Baltic Sea region wastewaters and natural waters are relatively cold during the major part of the year. This affects treatment processes.
