Following production it is necessary to introduce the ozone to the process medium. One of the

most popular methods is by means of porous diffusers mounted in a contact chamber.

APPLICATIONS•  Drinking water treatment

• Waste treatment

• Process related applications

MAIN CHARACTERISTICS• High mass-transfer efciency

• Even bubble formation

• Long service life

DOME DIFFUSERS KTL™ TECHNOLOGYIt is important that the ozone is introduced to the process in the

most efficient way. One of the more popular methods is to install

dome type diffusers at the bottom of a contact tank and to bubble

the ozone containing gas through the water volume in the tank.

The application, medium flow rate and ozone dose rate are critical

factors which will determine the size and number of dome diffusers

required and will also influence the geometry of the contact tank.

As an example, drinking water applications require a relatively low

ozone dose, short contact time and one ozonation chamber with

diffusers whereas waste treatment plants require a much higher

ozone dose, longer contact times and a multiple of ozonation

chambers.

HOW IT WORKSAfter leaving the generator the ozone containing feed gas is routed

to the process as quickly as possible. When porous diffusers are

used to introduce the ozone to the process, these are typically

located at the bottom of the ozonation chamber in a contact tank

with a hydraulic head of five to six meters.

The diffuser elements are designed that a cloud of homogeneous

small-sized bubbles are produced creating a large bubble/water

contact area to ensure a maximum mass-transfer rate.
