Our patented PerfluorAd® technology outperforms conventional approaches.
PerfluorAd® outperforms granular activated carbon (GAC), ion exchange resins (IX), nanofiltration (NF) and reverse osmosis (RO) in the treatment of PFAS contamination. It offers higher efficiency, lower costs, reduced maintenance and improved environmental protection.
What is PerfluorAd®?
The liquid active ingredient PerfluorAd® from the Cornelsen Group is continuously added to the PFAS-contaminated water.
Developed and patented in 2020 in collaboration with the Fraunhofer Institute UMSICHT, the active ingredient of PerfluorAd® represents the leading technology for PFAS treatment and offers unrivalled effectiveness and innovation.
PerfluorAd® is added to the contaminated water stream as a liquid medium, enabling a high contact frequency and effective binding of PFAS pollutants. This interaction leads to the precipitation and removal of PFAS and ensures cleaner water.
The dosage of PerfluorAd® can be adjusted in real time to the conditions of the raw water to ensure effective treatment and precisely achieve the desired target values.
The precipitation of PFAS by PerfluorAd® serves as a pre-treatment stage in which a filtration, flotation or sedimentation process is used to effectively remove the PFAS precipitated by PerfluorAd® and ensure thorough water purification.
This is followed by polishing stages, such as powdered activated carbon (PAC), granular activated carbon (GAC) or ion exchange resins (IX), to ensure complete removal. These modular solutions can be adapted to different water conditions and deliver optimum results.
The particular strength of the PerfluorAd®/PerfluorAd+™ process is that PFAS can be reliably removed even from heavily contaminated water with a complex mix of contaminants, i.e. water that is both high in organic matter and high in salt.
Why PerfluorAd®?
Highest possible effectiveness up to 99.9%, especially at PFAS concentrations > 10 µg/L
Excellent treatment results even with complex contaminated water: even heavily contaminated water that is both high in organic matter and high in salt can be treated reliably.
Significant cost reduction thanks to smaller activated carbon/ion exchange filters in the polishing stage, or a longer service life for these downstream filters.
High efficiency in water treatment thanks to the ability to dynamically adapt the treatment process to changing PFAS concentrations, flow rates and background loads.
Integration into existing treatment systems possible
Minimises residual waste volumes and disposal costs
PerfluorAd® process
The patented PerfluorAd® process is based on a liquid active ingredient that reacts with the PFAS in the system and forms stable flocs. These can be removed from the water by filtration, flotation and sedimentation. The advantage: cleaning is effective and efficient, gentle on the material and without the disadvantages of adsorption. The rinsing water is also treated directly on site, which minimises transport and disposal costs.
The example shown in Figure 1 indicates that, in addition to the PFAS that can currently be analysed, other "much more highly concentrated fluorine-containing water constituents" may be present in firefighting water. Figure 2 shows examples of elimination rates that can be achieved with the PerfluorAd® process. It is very clear from this that the PFAS currently categorised as particularly relevant (sum of 23 PFAS!) can be removed from the water by up to 99.9% when using the PerfluorAd® process.

PerfluorAd® can be seamlessly integrated into existing cleaning systems, significantly increasing the effectiveness of PFAS removal and cost efficiency.

Proven in practice with scientific expertise
In a funded project on PerfluorAd® technology, we and Fraunhofer UMSICHT investigated the effectiveness of PerfluorAd® in treating water contaminated with firefighting foam. The results show:
Up to 99.9 per cent (depending on matrix and load) of the PFAS contamination could be eliminated.
