PFAS is a group of over 4,700 substances. This means that the contamination looks different in different places. Jacobi has both the knowledge and the equipment to take care of the various contaminants in the best possible way.

PFAS – an issue that concerns us all

The current PFAS crisis is generating an increasing amount of concern amongst governments, the public and those in the activated carbon industry. These difficult to remove chemicals have made their way into water supplies, posing a threat to public health and triggering the development of new legislation from regulatory bodies. As a business, sustainability and environmental issues are a top priority for Jacobi and we feel it is our responsibility to take action to tackle this emerging challenge.


What Are PFAS?
Named the ‘forever chemicals’, the term PFAS refers
to per- and/or polyfuoroalkyl substances, a group of thousands of chemicals that are harmful to both humans and wildlife. Their chemical composition is extremely robust, and they are difficult to decompose. Though PFAS have been in use for decades, it is only recently that the extent of the problem has come to light, and, consequently, new regulations on PFAS levels are continuously coming into effect.

The Dangers of PFAS Contamination
Several peer-reviewed studies have shown that the effects on health can be serious. These studies have determined links to various types of cancers, liver malfunction, reduced immunity, reduced fertility, hormone interference, and developmental delays and behavioural changes in children.

How Does PFAS Contaminate Our Water?
PFAS are used in the manufacture of many everyday household items that we have close contact with on
a regular basis. Non-stick cookware and waterproof clothing or footwear being the most common sources, but you’ll also find them in food packaging, cosmetics, and carpets and upholstery. Use of these items on such a large scale means the chemicals make their way into our water sources, the land, and even the air, resulting in them finally ending up in our bodies and creating
a global crisis.

PFAS can spread long distances via air and water, the substances can be detected in areas where no production or use of PFAS has ever occurred. These substances have been found in places as far away as the Arctic and in polar bears that live there. PFAS is a global environmental problem.

Regulatory Developments

Across the globe authorities are implementing stringent regulations related to PFAS. One particularly notable update is the latest directive from the European Union.

The European Directive (EU) 2020/2184 on the quality of water intended for human consumption, transposed into local regulation in most European countries, has introduced PFAS into the drinking water standard for the first time, setting a limit value of 0.1µg/L for the sum of 20 PFAS. This strengthens the recent regulation from the European Food Safety Authority, establishing a tolerable weekly intake of 4.4 nanograms per kilogram of body weight for the sum of four PFAS: PFOS, PFOA, PFNA, and PFHxS.

This limit would mean that at the current PFAS levels in drinking water, a person of 70 kg should not drink more than three litres of water per week (meaning less than ½ litre per day), rather than the recommended 12 litres per week. To meet these food safety regulations, levels in drinking water will need to decrease.

According to a study by TZW, part of DVGW – German Technical and Scientific Association for Gas and Water, the sum concentration of 2.2 ng/L for four PFAS derived from the European Food Safety Authority study is exceeded in approximately 20% of all samples. To comply with this value in drinking water, around one in five waterworks in Germany would therefore have to operate treatment lines for PFAS removal if alternative water resources cannot be used.

Disposable food packaging is known to contain PFAS.


Current Solutions

Activated carbon and ion exchange resins are widely known to be the most effective solution. When the molecular weight of the chemical you are dealing with is lower, ion exchange resins are the best option and if the weight is higher, activated carbon performs best.

At Jacobi, we can offer a comprehensive, end-to-end service using either, or both, of these solutions, alongside the necessary personnel and equipment. This means you won’t need to source different areas of your solution from separate companies. All three businesses in the Jacobi Group come together to provide smooth running and effective PFAS solutions for our customers.

A Multi-Tier Approach to PFAS Removal

It is critically important to take a holistic view of the water quality, the treatment line and target and the local conditions, so as to define the right strategy.

Granular activated carbon (GAC) and ion exchange resins (IEX) are the two most common technologies to remove PFAS. They can be combined or used singularly, in different configuration options (single vessel, secondary polishing, lead/lag…).

GAC is already widely installed in water or effluent treatment lines as it can remove a large variety of contaminants that may be present in water sources (organics, disinfection by-products precursors, pesticides, etc.). PFAS removal can be one of its additional missions. Although the adsorption of PFAS mainly occurs in micropores, Jacobi offers a wide range of activated carbons, with different porosities, from micro to macro, to address the PFAS challenge in each water condition.

For example, PFAS-contaminated surface waters tend to have more bulk organic material than groundwater that makes them more challenging to treat, even without PFAS being involved. Using a GAC with narrow pores would result in pore blockage that may reduce the carbon’s ability to adsorb micropollutants such as PFAS. In this situation, Jacobi offers standardised grades from its AquaSorbTM range, as well as customer specific blends, such as AquaSorbTM Blend, to adapt to local conditions.

AC and IEX is the best solution for taking care of PFAS.

Jacobi Services – Mobile Filter Units

At Jacobi, we don’t simply provide the required product needed to tackle your PFAS problem. We are in a unique position that allows us to offer a full service including as much or as little of the equipment, technical know-how and personnel needed to ensure an effective solution.

This includes rental of mobile filter units, which we can arrange to be delivered and installed at your site by our team of PFAS removal experts. Filter sizes range from 200litre to 20m³ vessels and are able to treat flows from 100l/h to 80m³/h of water. As filters are modular, they can be arranged in series or parallel.

Our specialised teams can also deal with all the required logistics, including media handling, as well as any tests or evaluations that might be needed. Our goal is to provide you with every aspect of your PFAS solution in the quickest, easiest and simplest way possible.

In practice this means

  • Using test data and our extensive experience to help you to select the best products or product combinations.
  • Helping you to select the filters and flow conditions that will achieve the best possible technical performance. (PFAS is a micropollutant and so contact times are crucial for optimal removal of low concentration components.)
  • Providing process analysis and start up support that ensures the filter sequence provides the most costeffective and technically optimal performance.
  • Safe, clean and efficient logistics and media exchange with minimal impact on your personnel’s time.
  • Using closed systems approved for transporting the waste in a secure way without risk of spillage.

Reactivation of Spent Carbon and Disposal of PFAS, A Forever Solution

The PFAS problem holds a unique challenge. Normally an application is successful when the pollutants are removed and captured in the activated carbon. In the case of PFAS, only half of the problem is solved. Transporting captured PFAS to a disposal site, even in a concentrated form, will simply move the problem. A forever chemical needs a forever solution.

We have been working since 2022 to develop that solution and we are pleased to say that we now have it. Once transported to our European facilities we are able to reactivate spent carbon with PFAS in our high temperature kilns. Thus, breaking down the PFAS molecules into basic fluoride compounds. This process is monitored meticulously to ensure adequate and responsible processing and we have been certified with the relevant governmental body. This is a forward step in the forever solution and it’s the most sustainable way to manage concentrated PFAS waste activated carbon.

Being able to reactivate and reuse carbon is proven to have a far smaller negative impact on the planet than producing more virgin carbon, making it the most sustainable option. Finally, it is also far more cost-effective for the user too.
