Which devices are available to introduce ozone into the water?

The introduction of ozone into water is a critical process in water treatment that involves specific devices designed to efficiently dissolve ozone and enhance its contact with water. The correct answer is based on the types of devices used in this process.

Injectors are commonly used to create a vacuum that draws ozonated air or gas into the water stream, ensuring efficient mixing and mass transfer. Mixers are essential as they facilitate the uniform distribution of ozone throughout the water, preventing localized concentrations that could lead to ineffective disinfection or treatment. Spray chambers are also effective because they allow for the breaking up of ozone-rich water into smaller droplets, maximizing the surface area for contact with water.

This combination of an injector, mixer, and spray chamber maximizes the water treatment process by ensuring that ozone is effectively introduced, dissolved, and distributed throughout the treated water. The effectiveness of these devices in ozone introduction makes them the preferred choice in many water treatment facilities.

Other options do not include the same efficient or effective combinations of devices. For instance, options that list heaters or pumps may imply methods that are not typically used for ozone introduction, as the focus is on mass transfer devices that enhance interaction between ozone and water, rather than on heating or simply moving water without effective dissolution.
