Ozone sterilizes water through oxidation and subsequent filtration.
Ozone (O3) is a powerful oxidant used in water treatment to remove impurities and disinfect. The process leverages oxidation and filtration to achieve sterilization.
Ozone's Role in Water Sterilization
Here's a breakdown of how ozone works to sterilize water:
-
Oxidation of Inorganic Materials: Ozone oxidizes dissolved inorganic substances.
- Ozone oxidizes the iron, manganese, and sulfur in the water to form insoluble metal oxides or elemental sulfur.
-
Oxidation of Organic Materials: Ozone also breaks down organic contaminants through oxidation or coagulation.
-
Post-Filtration Removal: The insoluble particles created by oxidation are then removed through filtration.
Key Steps Summarized:
| Step | Description |
|---|---|
| Oxidation | Ozone reacts with and oxidizes iron, manganese, sulfur, and organic particles. |
| Byproduct Formation | Oxidation results in insoluble metal oxides, elemental sulfur, and coagulated/oxidized organic matter. |
| Filtration | The insoluble particles are removed through post-filtration, leaving cleaner, sterilized water. |
In essence, ozone treatment combines chemical oxidation with physical removal to purify water.
