The EU makes Southern Jutland greener
In Fredericia, right next to the Little Belt, Denmark’s second largest wastewater treatment plant is located. It sounds like the worst-case scenario for most environmentalists, but in Fredericia, the environment is taken seriously. The city makes sure that the water, which is discharged into the sea, is clean enough for the Little Belt's many harbour porpoises to thrive in.
Fredericia Municipality is part of the EU project “Energioptimering og affaldshåndtering”, which has the utility company Fredericia Spildevand og Energi as project partner. In 2017, the wastewater treatment plant received DKK 6 million from the EU Regional Development Fund to ensure a more sustainable development of the plant. Today, the wastewater treatment plant uses an advanced control method to monitor the wastewater treatment tanks. In this way, the chemicals that purify the wastewater can be dosed exactly according to the conditions. And thus, unnecessary chemicals in the water environment are avoided.
The plant has also tested and implemented a system that makes it possible to filter more sludge from the wastewater than before. The process has proven to be a win-win situation for the energy accounts. Once the sludge has been removed, the plant uses less energy to purify the water afterwards. At the same time, the sludge can be included in the production of biogas at the wastewater treatment plant. Therefore today, the plant is almost 100 per cent energy neutral.
