Ozone Injection/Contacting
The ozone injector serves two purposes: One, it creates the vacuum
required to safely draw the ozone gas from the ozone generator and
two, it provides a means by which the ozone gas can become
dissolved in water. A very dynamic injection process is required to
effectively dissolve ozone in water.
ClearWater Tech injection systems use only Mazzei® injectors for
maximum mass transfer efficiency. The injector produces a
cavitation effect, enabling the ozone gas to join the water stream in
the form of extremely tiny bubbles. These bubbles must be as small
as possible in order to increase the ratio of bubble surface area to
the amount of ozone entering the water.
Depending on the application and the water treatment goals, a ClearWater Tech contacting system may also be required.
Some oxidation reactions take place so quickly that they are limited only by the rate at which the ozone is dissolved in the
water. Other reactions, such as disinfection, may require that proper ozone residual be maintained for a specific amount of
time. A correctly-sized contact vessel is used for this purpose.
Ozone Destruct
The ClearWater Tech off-gas destruct systems, consists of two components - the ozone destruct unit (a heated chamber
filled with manganese dioxide and copper oxide) and a water trap. Used in conjunction with a ClearWater Tech off gas
vent, the ozone destruct system is an effective way to vent the contact vessel(s) when it is impractical to send the off gas
to atmosphere or reintroduce it to the water.
