How the pilot worked
The pilot used nanobubble generators, NanOxy-10 units, together with integrated bioremediation. The results on this page come from that combined approach, not from the nanobubble generators alone. The units were installed in January 2025, in a lake of about 10,000 m³. MBMC's certificate of appreciation names the challenges the project worked through: "water extraction and external pollution". We will add the full monitoring data to this page.
