Landfill leachate treatment
Landfill leachate poses a growing challenge for water protection - especially due to persistent PFAS compounds that are almost impossible to remove using conventional methods. The PerfluorAd® technology developed by Cornelsen offers a targeted and sustainable solution for effective PFAS elimination.
The invisible danger in landfill leachate
Landfills are essential for waste disposal - but at the same time they pose a growing risk to the environment and health. One particular problem area is leachate, which can be contaminated by PFAS. These persistent substances originate from everyday products such as textiles, packaging or industrial waste - and end up directly in our environment via household waste.
Leachates not only contain PFAS, but also high salt loads, heavy metals, organic loads and turbidity. This complex composition poses a major challenge for conventional treatment processes - especially for activated carbon and ion exchangers, whose effectiveness is impaired by this matrix.
With PerfluorAd®, Cornelsen offers a tried and tested solution for the targeted precipitation of PFAS. The biodegradable reagent selectively binds PFAS and separates them from the water in the form of solids. Subsequent treatment, e.g. by filtration, can reduce the residual load to below 10 ng/l.
Separation of particles and PFAS in one step
Robust performance even with high salt and organic loads
Customised system planning
Delivery of reagent and equipment
Can be flexibly integrated into existing systems
This approach is not only highly effective, but also reduces follow-up costs - because downstream filter systems or filter materials need to be maintained or replaced less frequently.
Already up to 80 % reduction directly in the leachate
The cleaning process in practice
Felling
Separation
Treatment of the floc residue if necessary
Disposal of the flake residue
In practice, precipitation with PerfluorAd® is carried out first, followed by separation by filtration or other processes. The residues are sent for thermal utilisation - with a minimum disposal volume (e.g. <50 g of solids per m³ of water).
Formed flocs in the filter
Proven results from practice
The use of PerfluorAd® has been tried and tested in practice - also in the field of extinguishing water or industrial wastewater. The analysis shows: The elimination rate depends on the dosage, but is highly effective even at low concentrations.
