The Science of Cleaner Water

A Paradigm Shift in Water Treatment

Nanobubbles are technically defined as gas bubbles under 1 micrometre (1,000 nm) in diameter. In practice, most commercial nanobubble systems — including the equipment Inpelor evaluates — concentrate their output well below that, typically under 200 nanometres, roughly 1/2500th the width of a human hair. Their advantage over conventional aeration comes down to geometry, not simply falling under a size threshold. For a fixed volume of gas, splitting it into smaller bubbles multiplies the total surface area in contact with water — and gas transfer happens at that interface. One litre of gas held as 100 nm nanobubbles presents around 60,000 m² of water-contact surface, roughly 20,000 times more than the same litre split into typical fine-bubble-diffuser bubbles (2 mm), and around 40,000 times more than a standard aquarium airstone bubble (4 mm). That surface-area advantage is what drives sustained oxygen transfer, oxidative remediation, and biofilm disruption. Inpelor provides independent, science-led guidance to identify where nanobubble technology delivers measurable results — and where it does not.
