Product Description
Ozone exhibits high solubility in water, with a solubility at 20℃ roughly 13 times greater than that of oxygen (around 0.35 g/L). The resulting aqueous solution is commonly referred to as "ozone water." While ozone in water is slightly more stable than its gaseous form, it should still be stored in a cool, dark environment, where it can remain effective for several hours below 4℃.

Mixtures containing a moderate partial pressure of ozone, and pure ozone at even low pressures are both potentially explosive.

Product Usage
Ozone offers a broad spectrum of applications. In water treatment, it serves as an effective disinfectant for drinking water, providing a safer alternative to chlorine while avoiding the formation of carcinogenic by-products. It is also suitable for treating industrial wastewater from dyeing and pharmaceutical processes, as well as urban sewage effluents, helping to decolorize and break down pollutants. Additionally, ozone can enhance water quality in aquaculture systems.
