Sustainable Industrial Waters – SIWat

Water is an important resource, and treating and reusing wastewater prevents scarcity, reduces pollution, and enables the recovery of valuable materials. Sustainable water management supports the long-term availability of water and contributes to a more resource-efficient society.
The SIWat project pilots the industrial reuse of reclaimed water to reduce dependence on municipal drinking water. Pilot will be implemented in Estonia and Finland to develop technologies and methods for recovering and purifying municipal wastewater and industrial process water for industrial reuse.
LUT’s role in this project is to develop a pilot-scale 3D-printed advanced oxidation reactor to treat MBR permeate from the Mikkeli wastewater treatment plant (WWTP) in Finland. Key activities include developing 3D-printed structured catalytic materials to improve purification efficiency, optimizing reactor design and catalytic performance, and set-up pilot systems to optimize techniques and operational parameters. LUT will also evaluate the cost-effectiveness of the water treatment technologies. The goal is to develop 3D-printed catalytic reactor systems that can purify municipal and industrial wastewater stream into high-quality water suitable for industrial reuse.

Goals

• Develop a pilot-scale 3D-printed AOP reactor system for water purification.
• Optimize reactor design, catalyst materials, and operational parameters for maximum performance.
• Purify MBR permeate from the Mikkeli WWTP.
• Perform cost analysis.
