Doranova is responsible for the treatment of waters originating from the pre-construction phase at the construction site of the Sulkavuori centralized wastewater treatment plant in Tampere, Finland. The main contractor in the project is YIT Infra Oy. In the pre-construction phase in 2018, the treated waters include leachate and excavation pit waters originating from the re-landscaping of the old landfill as well as from the pre-construction phase. Doranova will continue to remediate the contaminated leachate waters until the completion of the Sulkavuori centralized wastewater treatment plant in the end of 2024.
The automated water treatment system consists of e.g., an aeration unit, settling tanks for suspended solids, activated carbon filtration for water and air as well as an alarm system in the case of malfunctions.
