At a landfill, waste of various types is stored. When it rains on the landfill, different substances leach out over time, and leachate from the landfill represents an environmental hazard. Almost anything can be found in leachate, but often it includes suspended substances, transition metal ions, oil, and also PFAS.
Typical reductions of different categories of substances are presented below:
• Suspended solids: 90+%
• Transition metal ions: 90+ %
• Oil index: 90+ %.
• PFAS-4: 75 %
