Ozone CAS#10028-15-6
High Solubility – Ozone has excellent water solubility, about 13 times greater than that of oxygen at 20°C.
Efficient Ozone Water Formation – Easily forms ozone water with strong oxidative properties for various applications.
Improved Stability in Liquid Form – Ozone water is more stable than gaseous ozone, ensuring better usability.
Extended Storage Life at Low Temperature – When stored below 4°C and away from light, ozone water can remain effective for several hours.
Ozone CAS#10028-15-6
Ozone has excellent solubility in water. At 20°C, its solubility is about 13 times higher than that of oxygen (approximately 0.35 g/L). The resulting aqueous solution is known as “ozone water.” Its stability is somewhat greater than that of gaseous ozone; however, it must still be stored in a cool, dark environment, where it can remain effective for several hours below 4°C.

Product Usage
Ozone is widely utilized across various fields. In water treatment, it serves as an effective disinfectant for drinking water, providing an alternative to chlorine and preventing the formation of carcinogenic by-products. Additionally, ozone is applied in the treatment of industrial wastewater from dyeing and pharmaceutical processes, as well as in municipal sewage effluent, where it helps decolorize and degrade contaminants. It is also beneficial for enhancing the water quality in aquaculture systems.
