Ozone Bubble Diffusers – stainless steel

We have recently obtained some new Stainless Steel Ozone Bubble Diffusers.  These are excellent options for your simple ozone system using a bubble diffuser.  These diffusers are constructed of sintered stainless steel and offer a 20 micron rating bubble size.  Max flow rates are 2.7 CFM and 5 CFM.

We offer these diffusers in 2 sizes.  Each has a 6″ long diffuser attached to a pipe nipple with a 1/4″ Male NPT threaded connection.  The difference in sizes we offer are only diameter differences.  This allows more surface area of the diffuser itself, and therefore a higher maximum flow capacity.

Quantity discounts are offered for each diffuser, see our website for details on discounts.

Ozone Diffuser Features:

  • Sintered stainless steel construction is strong and reliable for many years of service
  • Threaded connection offers a solid seal to your piping or tubing
  • Hex nipple allows a wrench to be used to tighten or later remove the diffuser from your fitting or piping, this eliminates the potential of breaking the diffuser when twisting the sintered steel
  • Welded construction
  • 20 micron rating allows for very small ozone bubbles
  • 6″ length is sufficient to offer great surface area, but without the extra length to minimize damage

Tips for using a bubble diffuser:

  • Before attempting to dissolve ozone into water ensure you understand the principles of ozone solubility well.  Click HERE for more information
  • Water tank must be vented to safely remove excess ozone/oxygen from the tank
  • Diffuser should be placed at the bottom of the tank
  • Taller tanks and taller water heights will increase mass transfer of ozone into water as the water pressure is higher at the bottom of the tank, and the gas bubble must travel farther in the water.
  • Ozone generated from oxygen will dissolve into water more efficiently than ozone generated from air
  • Ozone generated at high concentrations will dissolve into water most efficiently, target the highest concentration ozone possible when using a bubble diffuser.
  • Colder water temperatures will achieve highest dissolved ozone levels.
  • Use counter-current water flows across the bubble diffuser

Drawing of example of ozone bubble diffuser in use

Above drawing gives a great example of how an ozone bubble diffuser can be used in a very simple system.  A great advantage to this system vs those that use a venturi injector is that there is no water pump required in this system, this is a very passive, and energy efficient system.  Many of the failure prone pieces of equipment of a traditional ozone injection system are not used in this system.  Consider this in your next ozone system.

A great opportunity to use an ozone diffuser is a simple bench-test system.  Set-up a column to dissolve ozone into constructed of glass or PVC.  We use PVC pipe and place a diffuser in the bottom of the pipe via a tee.  This allows the column to be 5-feet tall or more.  This allows a great opportunity to maximize ozone transfer into water.

The drawing above shows a complete system, if you are interested in setting a system like this up, let us know.  We sell and rent all this equipment, or can provide this testing for you in our facility.
