APPLICATIONS

Wastewater Ozonation

Ozonation is a wastewater treatment process that uses ozone to disinfect and purify water. Commonly used in municipal and industrial facilities, ozone generated from oxygen is injected into wastewater to break down pollutants, eliminate bacteria and viruses, and remove odors and colors. This process ensures cleaner and safer water for discharge or reuse.

What is ozone treatment for waste and wastewater?

Ozone treatment is a process that uses ozone (O₃), a powerful oxidizing agent, to disinfect and remove contaminants from waste and wastewater. It is effective in breaking down organic pollutants, killing pathogens, and reducing odors.

How does ozone treatment work in wastewater treatment?

Ozone is generated on-site and injected into the wastewater. It reacts with organic and inorganic substances, oxidizing them and breaking them down into simpler, less harmful compounds, and then decomposes back into oxygen.

What are the benefits of using ozone in wastewater treatment?

Benefits include effective disinfection, reduction of chemical usage, elimination of odors, improved water quality, reduction of sludge volume, and the ability to break down a wide range of organic pollutants and micropollutants.

How is ozone generated for wastewater treatment?

Ozone is produced using ozone generators, which create ozone by applying a high voltage to oxygen or air. The ozone gas is then dissolved into the wastewater through diffusers or contact chambers.

What types of contaminants can ozone remove from wastewater?

Ozone can remove a variety of contaminants, including bacteria, viruses, protozoa, organic compounds, pesticides, pharmaceuticals, industrial pollutants, and odor-causing substances.

Is ozone treatment safe for wastewater treatment?

Yes, ozone treatment is safe when properly controlled. Ozone decomposes into oxygen, leaving no harmful residues. However, safety measures must be in place to handle ozone gas safely and prevent exposure.

How does ozone compare to other disinfectants like chlorine in wastewater treatment?

Ozone is a more powerful oxidant than chlorine and can eliminate a broader range of pathogens without forming harmful by-products such as trihalomethanes (THMs) and haloacetic acids (HAAs) that chlorine can produce.

Who can provide ozone treatment solutions for wastewater?

Ozone treatment solutions are provided by water treatment equipment manufacturers, environmental engineering firms, and industrial gas suppliers specializing in ozone technology.
