AEIR IMPULSE launches pilot project in Sweden's municipal wastewater network

AEGIR Technology has officially launched one of Sweden's first pilot projects utilizing advanced nanobubble technology in an active municipal wastewater system to help reduce blockages, biofilm buildup, odor issues, and bacterial growth.

The ongoing pilot project covers approximately one kilometer of municipal sewer line operating under low-flow conditions, where grease accumulation and biofilm formation have historically caused operational problems.

The system uses AEGIR IMPULSE technology to convert naturally dissolved gases in the water into nanobubbles directly inside the pipe. Early observations indicate that the nanobubble environment significantly impacts both bacterial activity and organic buildup within the system.

Initial test results show promising performance

Initial laboratory and field measurements have yielded very encouraging results.

According to the initial data collected, the following has been observed:

• Significant reduction in bacterial activity
• Biofilm adhesion appears to have been reduced
• Grease deposits are becoming softer and less compact
• Odor levels in the sewer line have noticeably decreased
• The flow environment appears more stable despite low-flow conditions

Laboratory tests have shown up to approximately 90% reduction in bacterial growth under controlled conditions, while field observations continue to support the positive effects seen in the active municipal system.

A key observation is that while grease may still be present in parts of the low-flow pipeline, it no longer appears to form the same hard and aggressive blockages typically associated with sewer clogs.

The next phase is now underway

Following the positive early results, AEGIR Technology is now implementing its latest generation of the IMPULSE platform, featuring:

• Faster pulse sequences
• Higher system efficiency
• Improved electromagnetic control
• Enhanced industrial-scale capacity

The next phase of the project will focus on measuring long-term impact, system stability, bacterial reduction, and the overall effect on municipal wastewater infrastructure.

The company is also continuing the development of its industrial AEGIR IMPULSE model for larger municipal and infrastructural applications.

A new approach to wastewater infrastructure

The pilot project represents a significant step towards chemical-free wastewater treatment solutions through advanced nanobubble generation and adaptive impulse technology.

The goal is to help municipalities reduce maintenance costs, prevent blockages, minimize odor problems, and extend the lifespan of infrastructure without adding chemicals to the water system.

AEGIR Technology will continue to monitor and document the project as new results become available.
