Ozone Solutions Waterzone Series Installation & Operation Manual page 5

The process of converting oxygen into ozone is an
energy intensive process that generates a large
amount of heat. This heat must be removed from the
ozone generating cell for efficient and reliable opera-
tion. The ozone generator in this system uses a water
cooled cell to remove this heat. This does require con-
stant flow of cooling water through the cell to main-
tain sufficient ozone production.
This ozone/oxygen mix is dissolved into the water
using the Ozone Injection System. To efficiently dis-
solve this ozone into the water, a Venturi Injector is
used to pull the ozone into the water. The water pump
is used to increase water pressure prior to the venturi.
The pressure at the outlet of the venturi must be at
least 20 PSI lower than the inlet pressure. This pres-
sure differential creates a vacuum that will pull the
ozone into the venturi. This forceful action along with
the added mixing vanes in the venturi injector pro-
vides for an extremely efficient method of dissolving
the ozone gas into water.
Naturally, the excess oxygen and a small amount of
undissolved ozone must be removed from the water;
this occurs in the contact tank located on the skid.
Baffles inside this skid ensure that no oxygen/ozone
gas will escape with the water. All of the undis-
solved oxygen/ozone is removed through the vent on
the top of the contact tank so that it can be safely
destroyed or removed from the location.
The water passing through the Ozone Injection Sys-
tem is unimpeded and will flow at the desired rate at
the point of use. Water with dissolved ozone levels
necessary for proper disinfection can be used for any
purpose desired.
