Focusing on environmental aspects and efficiency, the new facility will showcase the latest advancements in sustainable wastewater treatment.

Borås, the second largest city in Western Sweden, has been committed to sustainable development and low carbon footprint since the 1960’s.

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

They also produce electricity in a combined heat and power plant and hydro power stations. By using their unique recycling model, they aim to convert the energy of the city's waste streams into renewable valuables, and create a city free from fossil fuels.

The new 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 and will meet the emission requirements in a much more efficient way. Hand-over of the plant is scheduled for November 2018.

Cutting-edge Veolia technologies will provide a complete wastewater treatment cycle, from modern pretreatment and biological treatment, including a flexible activated sludge process, to chemical treatment and sewer overflow treatment with the proven Actiflo process combined with Hydrotech Discfilters.

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

The treatment plant is designed with the most energy-efficient technologies and with the aim to produce sludge with the highest possible potential to generate energy in the nearby biogas plant. Phosphorous will be recovered mainly through biological treatment which allows this essential resource to be reused as fertilizer.

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

This system is based on online surveys, continuously ensuring optimized operation in regards to environmental conditions, energy consumption and costs.

It also provides a lot of flexibility, allowing the plant to be adapted to changing conditions caused by climate variations, for instance.
