Core Technology — Ultrafine Bubbles and Underwater Plasma

Core Technology

A 'Lung' that Revives the Ecosystem, a 'Scalpel' that Removes Pollution

Ultrafine bubbles (50–250nm) deliver oxygen down to the sediment layer to restore self-purification capacity, while underwater plasma generates OH radicals and ozone to directly decompose algae and refractory organic matter.

Ultrafine bubbles · the lung of the ecosystem

Oxygen is delivered to the deepest part of the lake, restoring self-purification. Anaerobic conditions improve and aerobic microorganisms revive the base of the aquatic ecosystem.

Underwater plasma · the scalpel on pollution

Underwater discharge generates OH radicals, ozone and other reactive species that rupture algal cell walls and break down COD, TOC and odour compounds.

Four properties of ultrafine bubbles
01Microscopic size

50–250 nm. Overwhelming surface area maximises contact with pollutants.

02Brownian motion

Self-diffusing without mechanical force, reaching the whole water body and the sediment layer.

03Long residence

Near-zero buoyancy keeps bubbles suspended for months, purifying continuously.

04Direct gas transfer

Bubbles attach directly to pollutant surfaces, rupturing and oxidising cell walls.

Reactive plasma species (OH·, O₃) are converted into ultrafine bubbles, maximising oxidation. Higher diffusion efficiency delivers both immediate and sustained purification.

Direct Algae Destruction Confirmed at the Cellular Level

Electron microscopy revealed 'ghost cells' — algae with destroyed cell membranes — after treatment. This scientifically proves the technology directly controls algae itself, rather than relying on indirect nutrient removal.
