Wastewater treatment plants to benefit 600 000 residentsTwo wastewater treatment plants in the Danube area of the Bratislava region are being upgraded to directly benefit over 600 000 residents in the area.
This ambitious project involves the complete modernisation of the existing Vrakuňa and Petržalka wastewater treatment plants. The upgrade reduces groundwater pollution and improves quality of life of all those connected to the sewage facilities. It also brings the city’s management of both facilities into line with EU legislative standards.
Significant works at the central plant
For the central waste water treatment plant known as Vrakuňa, the works involve transferring the existing process to one of Regenation, Anoxic, Denitrification and Nitrification, the so-called RADN system. In order to do this effectively and remove any traces of nitrogen and phosphorus, various works need to be undertaken. These include extending and replacing equipment in the existing aeration tanks, converting the existing 24 line system into two lines, upgrading the blower unit's technology, replacing the system of pumping return and excess sludge and upgrading various equipment in the secondary sedimentation tanks.
Replacing equipment for raking and sand washing is of vital importance for this plant. In addition, various technologies are being upgraded including fine screenings, sedimentation, aeration and thickening tanks, as well as pumping and transformer stations.
Benefits for locals
This project is improving the health and environmental conditions through the construction of sustainable sewage infrastructure. The health risks associated with contaminated water for residents and indeed visitors are disappearing as potable water becomes the norm. The region should also see a marked increase in tourism due to the cleaner environment and reduced health risks. This in turn is expected to trigger economic growth as more businesses set up shop in the area.
It is estimated that 36 direct jobs are being created as a result of the works.
