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.

To reduce COD, BOD, SS, SD, Turbidity, color, and odor.
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

Advantages of applying ozone in your industrial WWTP

Reduces COD and BOD

Pre-treatment

Industrial wastewater varies greatly depending on the sector and manufacturing process. Ozone is the ideal solution for pre-oxidation before the biological stage, as it removes contaminants and improves the COD/BOD ratio

Reduces SS, SD, color, odor...

Pouring Refining

Ozone applied to wastewater improves the physicochemical and microbiological parameters of the effluent, helping to reduce these parameters and ensuring compliance with discharge regulations for each industry

First a Pilot

Flow reuse

The new RD 1085/2024 establishes the basic regulations for water management, allowing wastewater reuse in different applications, and ozone is the ideal technology to achieve these parameters.

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.
