Ozone solution for odor problems
Use of Ozone in WWPS
Efficiency and sustainability in wastewater management: ozone treatment in WWPS
Wastewater Pumping Stations (WWPS) play a key role in the water cycle management, and the incorporation of clean technologies such as ozone treatment sets a new standard in sustainability. Ozone, a powerful oxidizing agent, effectively reduces odors, organic matter, and emerging contaminants before the water reaches its final destination (WWTP or outfall). This advanced solution improves environmental quality, eliminates odor problems caused by hydrogen sulfide (H2S), reduces the impact on sewage networks, and reinforces the commitment to more efficient and responsible water management.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
Issues with your WWPS?
Problems with direct discharge to outfall?
Odor issues in residential and recreational areas?
Hydrogen sulfide levels above regulations?
Want to improve the quality of the water sent to the WWTP?
Anaerobic bacteria proliferation in the pumping well?
High costs in the gas treatment systems of the pumping station?
Advantages of applying ozone in a WWPS
Total elimination of odors
Ozone effectively eliminates compounds responsible for bad odors such as hydrogen sulfide and volatile organic compounds. Its oxidizing action works instantly, improving the WWPS environment without generating waste or using additional chemicals.
Reduction of fat and sludge buildup
Ozone efficiently breaks down organic matter in wastewater, helping to disperse grease cakes and reduce sludge buildup. This improves pumping efficiency and decreases the need for frequent cleanings.
Improved water quality
Deep ozone bubbling ensures uniform diffusion in wastewater, promoting oxidation of organic compounds, pathogens, and contaminants. The result is a significant improvement in the quality of the pumped water and a cleaner, safer environment for subsequent processes.
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.
Ozone Injection Techniques in WWPS
Direct injection into the air chamber of the pumping well
This technique allows for the injection of ozone gas into the gas chamber above the water surface. This environment has a high hydrogen sulfide load, and ozone reacts to oxidize it.
Direct injection into the exhaust stack
This method is suitable for WWPS equipped with a channeled injection system. It consists of injecting ozone into the outlet pipe of the extraction stack to reduce odors before discharge into the environment.
Deep ozonation by bubbling
This is the most efficient technique, as it improves water quality, reduces surface grease layers, and lowers precursors that generate hydrogen sulfide.
