Key Applications and Value of Ozone Decomposition Catalyst in Water Treatment
In modern water treatment processes, ozone (O₃) is widely used for sterilization, disinfection, decolorization, odor removal, and degradation of organic pollutants due to its extremely strong oxidizing ability. However, if ozone remains in the water body or exhaust gas after the reaction is completed, it will not only cause corrosion to equipment materials but also pose risks to human health and environmental safety. Therefore, how to efficiently and safely remove the residual ozone has become a crucial aspect that cannot be ignored in ozone water treatment systems.
I. Typical Application Scenarios of Ozone in Water Treatment
Ozone technology has been widely applied in various sub-sectors of water treatment:
Municipal drinking water treatment: Deep oxidation of organic pollutants, removal of odor and color.
Wastewater treatment and reuse: Degradation of difficult-to-biodegrade substances (COD, trace organic matter).
Industrial wastewater treatment: Advanced oxidation treatment for industries such as dyeing, electroplating, and pharmaceutical wastewater.
Food and beverage industry: Used for sterilization and equipment cleaning (CIP system).
Semiconductor/electronics industry: Micro-pollution control in ultra-pure water systems .
In these applications, the exhaust gas resulting from the ozone reaction and the dissolved ozone must be effectively decomposed.
II. Why is an ozone decomposition catalyst needed?
Ozone has the following characteristics that necessitate its control and decomposition:
High oxidizing property → Causes long-term corrosion to pipes and seals
Instability → Easily decomposes but uncontrollable, may result in local high concentration
Safety risk → Inhalation of ozone will cause harm to the respiratory system
