Due to its concentration into gas, ozone needs efficient and appropriate contact devices.

POROUS DIFFUSERS
The diffusers are devices anchored to the bottom and made from an ozone resistant porous material forming many very fine gas bubbles. Diffusers are normally introduced in the bottom of the contact chamber below water level.


EJECTORS
Ejector or venturi systems can allow ozone to be introduced into liquid media with a higher pressure than that available in the ozone generator. It produces a flow containing many fine bubbles depending on the operating pressure and liquid/gas ratio.

SPECIAL PRESSURIZED CONTACTORS
Special reactors are designed to bring ozone into contact with organic substrates or water that must be oxidized with the aid of physical and chemical additives. As examples O3/H2O2- O3/UV – O3/CATALYSER – O3 and CATALIZED MEMBRANES.

IN LINE MIXERS
When the liquid media have a lower pressure than that inside the ozone generator, ozone can be combined with static mixers designed to mingle ozone in fine bubbles with the liquid.
