Ozone Solution Storage — Aqueous O3 Contact Basin and Off-Gas Destruct

Storing Ozone Solution? Start Here

Ozone is a powerful oxidant used in water treatment for its ability to disinfect and control pathogens. However, it's not something you can just store like other chemicals. Ozone is unstable and must be generated on-site, used immediately, and any excess must be safely destroyed. It's a go-to choice for municipal water treatment, cooling towers, and even bottled water disinfection, but its handling requires careful planning.

Can you store it in a poly tank?

No, polyethylene tanks are not suitable for storing ozone solutions. Ozone attacks most plastics, including HDPE and XLPE, leading to degradation. Instead, use materials like 316L stainless steel, PVDF, or PTFE, which are resistant to ozone's oxidative nature.

Key Issue: On-Site Generation

Ozone's instability means it must be generated at the point of use. This requires specialized equipment and trained staff to manage the process safely and effectively. The short half-life of ozone in water means it cannot be stored for later use.

The safety that actually matters

  • Ensure proper ventilation to manage off-gassing.
  • Use only ozone-compatible materials to prevent equipment failure.
  • Train staff on ozone handling and emergency procedures.

Common questions

Can ozone be stored for later use?
No, ozone must be used immediately after generation due to its short half-life.
What materials are safe for ozone contact?
Use 316L stainless steel, PVDF, or PTFE for ozone systems.
Is ozone safe for drinking water?
Yes, when used properly, ozone is effective for disinfecting drinking water without leaving harmful residues.
