Ozone Saturators

TMC Freshwater Ozone Saturator

Ozone has proved to be extremely beneficial in marine livestock holding facilities by controlling pathogens through sterilisation, enhancing water clarity by breaking down organic molecules such as phenols (yellow discoloration in the water) and aiding biological filtration by breaking down long-chain molecules and making them readily available for nitrification.

The traditional method of injecting ozone has been through the use of venturis on protein skimmers. Very fine bubbles with a high surface area to volume ratio can be produced in saltwater, which results in an efficient transfer of the ozone into the water. In freshwater, it is only possible to produce larger bubbles which prevent the formation of a stable foam.

TMC has produced a pressurised ozone saturator to inject ozone into freshwater. While this still relies on the initial injection of the ozone via a pump driven venturi, the ozone is pressurised in the reactor, resulting in a more efficient application. This is achieved by having the air outlet for the unit submerged below the water outlet level. As the pressure in the unit increases, the water level is forced downwards and excess gas is able to escape only once it has had time to fully react with the process water. This off-gas is lead through an ozone destructor in the form of a carbon filter, reducing local build-up of atmospheric ozone.

The unit is supplied with a flow meter (see pipework technical details), reaction vessel, venturi, ozone generator, Etatron redox controller, Zobells calibration fluid (see Calibration & Buffer Solutions), 5m of teflon tube and carbon filter.

Recommended Accessories

• Argonaut AV50 supply pump

• Double union ball valve for bypass and flow regulation

Depending on application, carbon will need to be replaced. Please check off-gas on a regular basis.
