Co to jest Ozonation?
Ozonation is a water treatment process that utilizas ozone (O ocau1; Xi1; FLT: 0 X3; Xi3; 3 XI1; FLT: 1 X3; XI3;) a strong oxidizing agent to degrade contrigants. Ozone is a triatomic contriule, a highly reactive form of oksygen, that is produced naturally in thee Earth 's stratoscule by ultraviolet light or during lightning storms. In industricting, ozone is generated onsite by passing air pure our pure oygene trigh a highvoltage dispare dispare dispare dispare (corongich. In industrichare, ther).
Once disolved in water, ozone reacts through gh twour primary pathways: direct condition proximation and indirect radical oxidation. In direct oxidation, ozone selectively attacks compounds with double solars, such as unsaturated organic dicules, phenols, and certain dyes. In indirect oxidation, ozone decomepose in water to produce hydroksyl dicals (501; 1EAD; FLT: 0; 3AH; 1AH; 1AF: 1; AH; AH; AH; AH; AE))) aid evevynful.

For optimal performance, ozone dosage and contact time must be carefully controlled.

Comparaing Ozonation with Alternativa Treatment Technologies

| Chlorination | Oxidation/halogenation | Low cost, residual disinfection | Forms THMs and other DBPs; can create toxic byproducts |
| UV Irradiation | Photolysis (DNA damage) | No chemicals, fast inactivation | No residual; requires high clarity water; can reactivate microorganisms |
| Advanced Oxidation (H₂O₂/UV, Fenton) | Hydroxyl radical generation | Very broad reactivity, mineralizes pollutants | Chemicals needed (H₂O₂, Fe²⁺); sludge production; pH dependent |
| Membrane Filtration (UF/RO) | Physical separation | Excellent removal of particles and dissolved salts | Fouling; concentrate disposal; high energy (RO) |
| Ozonation | Direct and radical oxidation | No persistent residues; effective on many organics and microbes | Energy intensive; no residual disinfection; byproduct risk (bromate) |
