Overview

Ozone treatment is a widely used method for purifying, disinfecting, or modifying the chemical properties of water. When introducing ozone into a liquid stream, the efficiency of gas dispersion becomes critical. Stainless steel sparging stones are a proven tool for generating fine, uniform bubbles that enhance mass transfer between ozone gas and water.

This post explains their suitability, optimal pore size, and considerations when selecting the right stone for ozonation applications.

Can Sparging Stones Be Used for Ozonating Water?

Short Answer: Yes. Stainless steel sparging stones are fully compatible with ozone and can be used to effectively “ozonize” water. Their corrosion‑resistant metal construction withstands oxidative environments, making them ideal for continuous or batch ozonation processes.

Recommended Pore Size

For best performance, a 10 µm pore size is recommended.
Smaller pores generate finer bubbles, which:

• Increase surface area
• Improve contact efficiency
• Enhance ozone dissolution
• Promote consistent treatment across the water volume

This makes 10 µm stones the preferred choice for most general ozonation needs.

Why Stainless Steel Stones Work Well with Ozone

Chemical Resistance
Stainless steel maintains structural integrity even under highly oxidative conditions, unlike certain polymeric materials that may degrade or embrittle.

Consistent Porosity
Uniform pore distribution ensures repeatable and predictable bubbling behavior.

Durability
Stainless steel stones support repeated use, cleaning, and sterilization without losing performance.

Applications

Sparging stones are commonly used in:

• Water purification and treatment systems
• Laboratory ozonation experiments
• Dissolved ozone generation for analytical methods
• Environmental and industrial water conditioning setups

Their ability to generate fine bubbles ensures efficient ozone transfer regardless of the scale of operation.
