Ozonia Radial and Dome Diffuser Technology

Ozonia Radial Diffuser is a highly efficient alternative mass transfer in a compact footprint for a wide range of water treatment applications including drinking water and wastewater.
Dome diffusers are a simple and efficient method to transfer ozone into the water to be treated. The diffusers are commonly installed in a grid at the bottom of a contact tank and to bubble the ozone-containing gas through the water volume in the tank.

All ozone applications benefit from high efficiency ozone gas mass transfer. The radial diffuser is a highly efficiency alternative to traditional bubble columns which use porous diffusers. Trust Veolia engineers to define the application and ozone dose rate which determine the size and positioning of the radial diffuser in the contacting system. After leaving the generator the oxygen and ozone gas mixture is routed to the water treatment process. Ozonia Radial Diffusers offer plant designers an elegant method of introducing ozone into processes with a minimized footprint, particularly when there are space restraints.

Ozonia Radial and Dome Diffuser Technology

The main component of a radial diffuser system is the injector which mixes the ozone containing feed gas with a relatively low motive water flow. In turn, this motive water flow is routed to a radial diffuser head. The throwing power of the diffuser head ensures that the motive water containing the ozone is intensively mixed with the
process medium.

The radial diffuser elements are designed so that in addition to the ozonated motive water, a cloud of homogeneous small-sized bubbles are produced creating a large bubble/water contact area to ensure a maximum mass-transfer rate. Radial diffusers are easily integrated in pipe systems as well as in contact chambers. If the operating parameters allow, it is also possible to use the Ozonia mixing tube.
