BORÅS, Sweden - Veolia Water Technologies, through its subsidiaries VA-Ingenjörerna and Krüger, has won a SEK 400 million (approximately EUR 42.5 million) contract to design and build a wastewater treatment plant in Borås, Sweden.

The Borås Energi och Miljö´s (BEM), who awarded the contract to Veolia, provides the city of Borås with district heating, district cooling, biogas, waste management, water and sewage treatment and energy from waste services.

The wastewater treatment plant will be co-located with the local power plant at the new Energy and Environmental Center south from Borås.

The new facility will have a 210,000 Population Equivalent capacity with a hand-over of the plant scheduled for November 2018.

Veolia technologies will provide a complete wastewater treatment cycle, from pre-treatment and biological treatment, including an activated sludge process, to chemical treatment and sewer overflow treatment with the Actiflo process combined with Hydrotech Discfilters.

Reject water will go through the Anita Mox process, particularly suited for streams highly loaded with ammonia.

One of the aims of the pre-treatment plant is to produce sludge with the highest possible potential to generate energy in the nearby biogas plant. Phosphorous will be recovered mainly through biological treatment to be reused as fertiliser.

Advanced control and monitoring will be provided throughout the plant by STAR Utility Solutions.
