Treat leachate with ozone

Scientists at the University of Science (Thai Nguyen University) have successfully applied the method of using strong oxidizing ozone agent to treat persistent organic compounds in leachate in the solid waste landfill in Thai Nguyen city.

Using ozone to treat persistent organic compounds in leachate is a new study of the University of Science (Thai Nguyen University).

Equipment will be helpful in criminal forensics or national security

After 50 minutes of treatment with ozone, suspended solids, persistent organic matter in leachate is drastically reduced. The content of persistent organic matter decreased by 65.4%, the content of suspended solids decreased by 100%.

According to Dr. Van Huu Tap, Department of Environmental and Earth Sciences, University of Science (Thai Nguyen University), the research shows that ozone can strongly oxidize different substances so the application of ozone to Waste water treatment is a promising direction.

Vietnam currently has about 100 solid waste landfills and all have leachate treatment systems but over 80% of treated wastewater does not meet the standards of discharging, causing air pollution and surface water pollution. , groundwater in residential areas.
