Nanobubbles are up to 2,500 times smaller than a grain of salt – so small they don’t rise to the surface but stay suspended in the water for days, weeks, or even months.
Their extremely small size allows them to penetrate biofilm, disrupt bacterial environments, and break down organic material.
Thanks to their high internal pressure and strong negative charge, nanobubbles have a documented antibacterial effect – while improving water quality at a microscopic level, without the use of chemicals.

When a nanobubble collapses, it releases intense energy that triggers chemical reactions in the water – including the formation of hydroxyl radicals (OH•), which are extremely reactive and break down organic material, biofilm, and algae.
This microscopic process acts as a self-generating cleaning mechanism within the water, reducing biological contaminants from the very first stage.
The result is clearer water, less clogging, and significantly better conditions for downstream treatment such as PFAS filtration.

The nanobubbles are created through hydrodynamic cavitation – directly from the oxygen or air already dissolved in the water.
The system requires no external gas supply in its standard configuration but can be supplemented with oxygen, ozone, or other gases if needed.

Leachate often contains high levels of organic material, biofilm, algae, odor compounds, as well as metals and PFAS.
This high biological load leads to clogging, shortened filter life, and reduced treatment efficiency.
Algae and biofilm easily get trapped in filter media, increasing the need for backwashing, chemicals, and frequent replacements – which drives up both costs and operational disruptions.

They improve water quality already during the pretreatment phase.
Nanobubbles increase oxygen levels, reduce biofilm, dissolve sludge, organic matter, and algae – making subsequent steps like filtration, chemical precipitation, and PFAS treatment more effective and cost-efficient.

Nanobubbles reduce the amount of particles and biofilm that would otherwise burden carbon or membrane filters.
This leads to fewer filter changes, more consistent flow, and improved PFAS removal performance.

Initial effects are often visible within a few days – such as clearer water, reduced odor, and better flow.
Other improvements, like lower BOD/COD and fewer blockages, appear progressively depending on water volume and contact time.
