Ozone in industrial WWTP
Industrial wastewater treatment with ozone
Use of ozone in industrial WWTP
Industrial wastewater contains a wide variety of pollutants depending on its origin and type of industry, making it sometimes very complex to treat in order to comply with current discharge regulations. Ozone is a well-established technology in Industrial WWTPs as it allows solving complex problems in a very simple way.
Pre-oxidation of the flow before the biological stage to improve the COD/BOD ratio. Tertiary Treatment for Reuse to be used again in the industry.
The strong oxidation capacity of ozone makes it an excellent tool for any of these stages, Ozone is a simple and safe technique that achieves the most demanding results.
ZonoSistem advises detailed engineering for project drafting, as well as designs and manufactures ozone generators for real projects.
Carry out a Water Piloting with ozone in our laboratory before making the investment.
Ozone is a powerful oxidant applied to water for purification
Ozone is generated on-site, eliminating the need for chemical storage and transportation
Ozone contributes to sustainability and reduces the carbon footprint
The system is automated and does not require manual labor for application

Ozone Injection Points in IWWTP and Objectives
Pretreatment before biological
Industrial wastewater is very diverse, depending on the type of sector and the manufacturing process. Unlike urban wastewater, the composition received by the IWWTP is highly variable and unstable, with changes in flow, temperature, and contaminants. Ozone is the solution for pre-oxidation before the biological stage, as it removes contaminants such as detergents, reduces organic matter, pre-oxidizes recalcitrants, and above all, improves the COD/BOD ratio, making the water more biodegradable.
Polishing post-treatment
If the biological treatment works properly and pretreatment is not necessary, but the discharge value is very high due to the initial composition of the effluent, ozone can act as a polishing treatment, reducing color, turbidity, and final COD. This results in reduced discharge fees or even compliance with discharge parameters.
Pre-treatment
The IWWTP may work perfectly, but water reuse for the industrial process can be considered. The new RD 1085/2024 establishes the basic regulation for water management, allows the reuse of wastewater in different applications, and ozone is the ideal technology to achieve these parameters.
Advantages of using ozone in IWWTP
Without labor, automatic
The system generates ozone and injects it into the tank automatically, without the need to apply manual labor in the process. The equipment only needs to be connected to the tank to be treated and provide it with a point of light.
No chemical storage
Ozone cannot be transported or stored, it is generated on site, and it is applied instantly, so it is not necessary to store and manage chemical products, it avoids transport and reduces the carbon footprint.
Agent recognized by the ECHA
Ozone is recognized by the European Chemical Agency and ZonoSistem has all the necessary legalization documentation to be able to apply ozone in its process.
