Viikinmäki WWTP + Anitamox process + RAVITA™ process
Viikinmäki is the largest WWTP in Nordic countries (PE 800 000) and is aiming at energy neutrality by e.g. applying side-stream anammox, by recovering heat and by using solar panels. This visit also includes the RAVITA™ pilot, an innovative new method for phosphorus recovery. All the steps of the enhanced nutrient removal process are placed in rock tunnels.
