Virtual Technical Tour

Virtual Tour 1: Viikinmäki WWTP

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.

Virtual tour 2: Hermanninsaari WWTP + Old Porvoo and archipelago visit

This small treatment plant has many times achieved the best treatment results in Finland. In 2018 the conventional activated sludge treatment was upgraded with a disc filtration unit capable of treating both secondary effluent and by-pass waters. The virtual visit also includes a visit to the historical Porvoo town in a picturesque location by the Porvoo river and the beautiful Porvoo archipelago. The virtual visit is produced by a group of students from Aalto University Department of Built Environment.
