MIT BOTTLED WATER OZONE SYSTEMS
Ozone (O₃) is a highly reactive gas made of three oxygen atoms. It’s a natural oxidizer—stronger than chlorine—and when used in water treatment, it destroys bacteria, viruses, fungi, and other pathogens almost instantly. After doing its job, ozone reverts back to oxygen, leaving no chemical residue behind.
Ozone systems are typically installed at the final stage of bottling, just before water is filled into containers. Here’s how it works:
- Ozone Generation: Ozone is produced on-site using an ozone generator, which applies an electrical charge (corona discharge) to oxygen or dry air.
- Ozone Injection: The ozone gas is dissolved into the purified water using a venturi injector or bubble diffuser.
- Contact Time: Water is held briefly in a contact tank to allow ozone to neutralize any remaining microorganisms.
- Bottling: The ozonated water is then filled into bottles, which are also sanitized by the residual ozone.
This process ensures that both the water and the packaging are free from microbial contamination.
Why Bottled Water Needs Ozone
- Microbial Safety: Ozone eliminates bacteria, viruses, and spores that might survive filtration.
- Shelf Life Extension: Prevents microbial growth during storage and transport.
- Taste & Odor Control: Removes unpleasant tastes and smells without adding chemicals.
- Eco-Friendly: No harmful by-products—ozone breaks down into oxygen naturally.
