What method is used to introduce ozone into water?

The method used to introduce ozone into water is through fine bubble diffusers. This process involves creating small bubbles of ozone gas that are dispersed throughout the water. The large surface area of the fine bubbles allows for efficient mass transfer of ozone, facilitating its dissolution and ensuring that it effectively interacts with contaminants in the water.

Using fine bubble diffusers is advantageous because it maximizes contact time between the ozone and the water, making the disinfection process more efficient. Since ozone is a powerful oxidizing agent, its effectiveness in treating water relies heavily on how well it can be mixed and dissolved within the water matrix.

Other options, such as air stripping towers, are designed to remove volatile compounds from water rather than inject ozone. Potassium permanganate is an oxidizing agent itself but is not a method for introducing ozone. Ultrasonic transducers can be used to enhance mixing in some applications, but they are not the standard method specifically for ozone injection. Thus, fine bubble diffusers provide the most effective means of introducing ozone into water treatment systems.
