Important results from the project
The project´s goals were achieved by demonstrating direct membrane filtration, anaerobic treatment, and nutrient recovery from wastewater. Beyond the planned results, the project created important synergies through international collaborations and strengthened links to other initiatives in sustainable water management and the circular economy, paving the way for future joint efforts.
Expected long term effects
The project is expected to enable long-term reuse of wastewater to drinking water quality, increased energy recovery through biogas production, and efficient recycling of nitrogen and phosphorus. The technology can help reduce climate impact, promote circular resource flows, and create sustainable treatment solutions, especially for smaller communities. Results provide key knowledge for future resource recovery facilities and support Agenda 2030 goals.
Approach and implementation
The project followed a plan with pilot trials for membrane filtration and anaerobic treatment, and nutrient recovery in laboratory scale. Main activities were carried out as planned. Some adjustments were made, such as improved pre-treatment to reduce operational issues. The timeline was mostly followed, with slight delays in lab trials. External factors, like limited data access, partly affected evaluation. Collaboration with our Brazilian partner and ENWA worked very well.
