Ozone CAS#10028‑15‑6
Ozone demonstrates outstanding water solubility. At 20°C, its solubility reaches roughly 0.35 g/L, around 13 times that of oxygen. Its aqueous solution, commonly referred to as ozonated water, delivers improved stability compared with gaseous ozone. Nevertheless, cool‑dark storage is still required. Maintained below 4°C under light‑shielded conditions, ozonated water can preserve its activity for several hours.

Ozone CAS#10028‑15‑6
Ozone is a powerful oxidizing agent with remarkable water‑soluble performance. At 20°C, its water solubility is around 13 times higher than oxygen, readily forming high‑activity ozonated water with strong oxidation capacity. Ozonated water features better stability than gaseous ozone. Stored below 4°C and protected from light, it can maintain effective activity for several hours, supporting diversified applications across water treatment, disinfection and other industrial fields.
Product Usage
Ozone enjoys broad‑spectrum application across multiple industries. Within water‑treatment scenarios, it acts as an efficient disinfectant for drinking‑water disinfection. As an alternative to chlorine‑based disinfection, it avoids the generation of carcinogenic disinfection by‑products. Furthermore, ozone is deployed for the treatment of printing‑dyeing wastewater, pharmaceutical‑process wastewater and municipal sewage. It delivers reliable performance in decolorization and pollutant degradation. Besides, it can effectively improve water quality for aquaculture systems.
