The PFAS Challenge

The PFAS family comprises approximately 4700 different man-made compounds categorised into different sub-sets. For over 60 years PFAS were used in the manufacturing of many products which led to their widespread release into the environment.

The physio-chemical properties of PFAS make them extremely resistant to natural degradation and they are often referred to as “forever chemicals”, due to their persistence in the environment, such as in soil and water. They are hard to treat and conventional technologies in many cases cannot meet removal demands.


Overwhelming evidence has connected PFAS to severe health effects, such as several types of cancer, and compromised immune-responses, which is now under a spotlight due to Covid-19.


A wave of regulation is now setting PFAS maximum contaminant levels to mitigate population exposure. In February 2020, US Congress approved the PFAS Action Act (2019) and the EU Water Framework Directive was amended to include 20 PFAS compounds.

The PFAS Challenge


The company has developed a novel platform technology that facilitates surface modification of a range of select substrates with tailored “PFAS-friendly” molecular groups. The result is a suite of adsorbent materials, exhibiting high selectivity towards diverse PFAS compounds adaptable for multiple applications.


How It Works



The market for treatment of PFAS is driven primarily by regulation and cuts across a wide range of sectors and geographies.


Environmental Remediation

PFAS infiltration into groundwater requires a dedicated approach to enable effective remediation of polluted groundwater sites. Our adsorbents can be implemented easily, enabling retrofitting of existing assets if required. The highly selective PFAS adsorbent requires shorter Empty Bed Contact Times, leading to lower footprints and lower CAPEX. The flexibility of the solution enables application in diverse sites and scenarios.

Potable Water Treatment

Potable Water Treatment

New regulations are now requiring utilities to implement treatment solutions to ensure potable water supply is safe. Our adsorbents are adaptable to large volume applications, and are designed with a high selectivity and high adsorption capacity, leading to lower footprints, less downtime, lower change-out frequency and attractive lifecycle costs.



POU systems can serve as an affordable frontline barrier to PFAS for affected communities. Our unique technology platform and production methods allow functionalisation of various substrates, hence our technology can be applied in diverse formats to meet a wide range of POU system demands.

Point of use


Manufacturing Facilities

Many manufacturing facilities are required to treat their wastewater to meet stringent regulations prior to discharge into the environment or the municipal sewage system. Our adsorbents are designed as a polishing step in an industrial wastewater treatment process, whilst also considering high concentrations of PFAS, typically present in this application.

Military Bases 

The use of Aqueous Forming Foams (AFFF) has exposed many airports and military bases to environmental challenges pertaining to PFAS contamination in groundwater and run-off water. Our adsorbents can be tailored to remove different classes of PFAS at varying concentrations, depending on the circumstances. An easily deployable and effective treatment solution can be designed for meeting environmental discharge permits.
