An ozone system in a wastewater treatment plant (WWTP) is a method of disinfecting and treating the wastewater to remove impurities and contaminants. Ozone is a powerful oxidizing agent that can effectively kill bacteria, viruses, and other microorganisms in the wastewater. It can also help to remove odors and improve the overall quality of the treated water.
Wastewater from wastewater treatment plants can contain a variety of pollutants, including BOD, COD, color, phenols, cyanides, sanitary waste, and other complex chemicals. Due to its strong oxidizing properties, ozone can treat complex industrial wastes in combination with other physical, chemical or biological processes. Ozonation breaks down organic molecules into smaller biodegradable components, and in some cases into carbon dioxide.
In an ozone system for a WWTP, ozone gas is generated using an ozone generator and injected into the wastewater stream. The ozone gas reacts with the organic matter in the wastewater, breaking it down into simpler compounds. These systems can reduce TOC (total oxygen demand), BOD (biochemical oxygen demand) and COD (chemical oxygen demand) levels in wastewater including the removal of specific chemical species. Our systems are also used to eliminate pathogens from water and reduce contamination in ballast water before it is discharged from cargo ships. After the ozone has been injected into the wastewater, it is typically allowed to dissipate into the air before the water is discharged into the environment.
Ozone systems are often used in conjunction with other wastewater treatment technologies, such as biological treatment processes, to provide a more comprehensive and effective treatment solution. Ozone systems are also relatively easy to operate and maintain, making them a popular choice for many WWTPs.
