Deep analysis of the principle of ozone micro nano bubble water sterilization and disinfection technology

The oxidation mechanism of ozone

Direct oxidation: Ozone molecules (O3) disrupt the phospholipid bilayer in microbial cell membranes, leading to cytoplasmic leakage and structural disintegration.

Indirect oxidation: After ozone decomposition, hydroxyl radicals (· OH) are generated, which have stronger oxidation ability and can indiscriminately attack microbial proteins, enzyme systems, and genetic material (such as DNA/RNA), blocking their metabolic and reproductive functions.

Broad spectrum killing: Effective against bacteria (including spores), viruses, fungi, protozoa, etc., especially against chlorine tolerant pathogens (such as Cryptosporidium).

The synergistic effect of micro nano bubbles

High solubility and slow-release effect: Micro nano bubbles, due to their extremely high surface area/volume ratio, significantly increase the ozone dissolution rate (up to 10 times that of traditional aeration methods), and continuously release reactive oxygen species during the slow rise process, prolonging the action time.

Interface charge effect: Negative charges on the surface of bubbles attract positively charged microorganisms, enhancing local ozone concentration and reaction efficiency.

Cavitation effect: The rupture of bubbles instantly generates local high pressure and high temperature, physically damaging the structure of biological membranes and assisting in chemical disinfection.

Technological advantages and application value

Performance advantages

Super permeability: Micro nano bubbles can penetrate biological membranes and complex pipeline structures (such as blind ends and threaded interfaces), solving the problem of blind spots in traditional disinfection.

Environmental compatibility: Ozone has a short half-life (about 20 minutes in 20 ℃ water), decomposes into O ₂ without residue, and is suitable for industries such as food and medicine that require high cleanliness.

Anti biofilm ability: By oxidizing polysaccharide protein complexes, the biofilm matrix is disrupted, regeneration is inhibited, and the risk of secondary pollution in pipelines is reduced.

Economic and operational advantages

Energy saving and consumption reducing: Micro nano bubble technology reduces the amount of ozone added (reducing the amount by 30%~50% under the same effect), combined with automation control to further optimize energy consumption.

Convenient maintenance: No need to frequently replace disinfectants or clean residues, reducing downtime and improving continuous production efficiency.

Strong adaptability: It can be integrated into existing water treatment systems and is suitable for various scenarios such as circulating water systems, storage tanks, pipeline networks, etc.

Safety and Compliance

Low risk operation: The closed system design avoids ozone leakage, and the concentration sensor monitors in real-time to ensure a safe threshold (≤ 0.1 ppm).

Compliance certification: Compliant with FDA, EPA, and EU drinking water standards, suitable for disinfection needs of export product processing equipment.

Typical application scenarios

Food and beverage industry: CIP (in-situ cleaning) disinfection of production line pipelines and storage tanks, replacing traditional hot water or chemical sterilization.

Medical field: Final disinfection of endoscopes and surgical instruments to avoid toxic residues such as glutaraldehyde.

Water treatment system: biological pollution control of circulating cooling water and direct drinking water pipeline network.

Agriculture and aquaculture: inactivation of pathogenic microorganisms in irrigation water and aquaculture water bodies.
