Circular solutions for :

Timisoara is located in western Romania and the country’s third largest city.

The city’s waste water treatment plant (WWTP) is designed for a 440,000 population equivalent (PE) and an average flow of 250 000 m3  per day. It is managed by Aquatim, who operate 28 drinking water treatment plants and 22 WWTPs.

Wastewater enters the treatment plant through four main sewers and goes through the mechanical and advanced biological treatment facilities, prior to be discharged into the Bega river. Today, the aerobically stabilized excess sludge is dewatered, solar-dried and landfilled. For a future-proof sludge handling, more sustainable alternative solutions have to be found.

Relevant sectors

Key innovations & actions

  • Demonstrate sludge management with production of by-products and energy via pilot-scale testing of thermochemical conversion. The pyrolysis technology (via thermo-catalytic reforming) demonstrated will focus on aerobically stabilised sewage sludge to produce biochar, oil and gas. These products can be exploited energetically as fuel or soil enhancing agent or sorbent.
  • Feasibility study of water reuse. Investigate potential applications for effluent from the Timisoara and other AQT WWTPs. Assessment of options in the urban, industrial and agricultural sector.
