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 nutrient recovery, removal of micropollutants, and energy and GHG optimization – all this in wastewater treatment and especially in cold climate conditions.  

Nutrient recovery from wastewater

The role of wastewater treatment is moving from the removal of substances to the recycling of resources.

Nutrient recovery and removal system

Emerging pollutant management

The load of different pollutants in the Baltic Sea is a problem we need to solve.

Micropollutants research system in water laboratory

Climate impact of WWTP

Wastewater treatment plants are among the big energy consumers in our societies and they have a significant carbon footprint.

Carbon sink

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.
