Dioxin removal Fe-DS system
We can remove dioxins from the leachate of the final disposal site that exceeds environmental standards and bring it below the discharge standards.
The leachate from the final disposal site contains a high amount of unburned carbon derived from organic matter and incineration ash, and often does not lose color even after the addition of coagulants. In such cases, the concentration of dioxins does not significantly decrease. As a countermeasure, the Fe-DS system is effective. By using a combination of ferrous iron, caustic soda, and Ultra Separate S-DS for coagulation, very clear treated water can be obtained. This treated water has a neutral pH and can meet the environmental standards for dioxins, including the river discharge standards. In examples of dioxin wastewater treatment, the concentration of dioxins can be reduced from 30 pg-TEQ/L to below 1 pg-TEQ/L after treatment.
