We created PFASER to help eliminate PFAS (per- and polyfluoroalkyl substances) and perchlorate from water—on-site, and at scale. It’s our answer to a growing global challenge: how to treat persistent contaminants. 

Our electro-oxidation system uses patented long-lasting boron-doped diamond (BDD) electrodes to break down pollutants at the molecular level. No concentrated liquid reject or sludge to manage. Main consumable: electricity. 

Just clean water, simplified operations, and on the long term a smarter path to compliance. 

Why “forever chemicals” are a growing risk

PFAS are found just about everywhere—and they don’t break down easily.  This is why they are called eternal pollutants.  

These “forever chemicals” contaminate water, disrupt operations, and threaten public health. Regulations are tightening. Expectations are rising. And traditional treatment methods can’t keep up. 

PFASER gives our clients an efficient method to eliminate persistent contaminants in water. Its adaptability makes it a powerful tool for industries and communities facing serious PFAS contamination in water.

PFASER: The electro-oxidation solution

PFASER - Closed Loop Modular Design-2

Closed-loop, modular design

PFASER is a modular thus scalable destructive technology, closed-loop electro-oxidation system that breaks down PFAS, and other persistent contaminants in water. It also provides a treated discharge with no detectable concentration of perchlorate thanks to WSP’s proprietary perchlorate removal process. 

It’s fast, field-proven, and built for industrial scale. The system is designed for flexibility and stability—whether deployed as a mobile containerized unit or integrated into a permanent treatment hub, it adapts to your site and your needs. 

Patented boron-doped diamond electrodes

WSP uses long-lasting BDD electrodes to generate hydroxyl radicals and electrons that destroy PFAS molecules—including PFOS and PFOA (Perfluorooctanoic acid)—converting them mainly into carbon dioxide, water and fluorides. These patented electrodes have been used in commercial applications for over a decade. WSP has the exclusivity on these electrodes for the treatment of PFAS in liquids through our partnership with pro aqua Diamantelektroden Produktion GmbH. They are engineered for chemical stability, physical durability, treatment efficiency, and minimal maintenance.

Our team works closely with yours to assess co-contaminants present in water, treatment goals, and site constraints. Whether you need a simple treatment or a fully integrated advanced system, we build it to fit. 

Why PFASER delivers results


4 Why PFASER Delivers Results2

Destruction technology 

We don’t trap PFAS—we destroy them.  PFASER breaks the carbon-fluorine bond, minimum 95% of total PFAS mass destruction. The greater the PFAS concentration, the higher the PFAS removal rate!  

Minimum waste 

No concentrated liquid reject or sludge produced. Minimum coarse filter if required, polishing media and chemicals used. Its primary consumable is electricity, used to destroy contaminants.  

Built to scale—Any site, any flow 

PFASER adapts to your site. Mobile or permanent. After treatability proven in lab-scale testing, it has the potential to treat PFAS and other contaminants in industrial waters, groundwaters or leachates.  

Lower lifetime cost 

Long-life BDD electrodes mean low operating and maintenance costs. Just savings on the long term.  

Proven results  

Backed by a decade of research and development and real waters testing and real world deployments. Validated. Reliable. Ready.  

Built for the industries that need it most

PFASER is built for industries facing complex water challenges: 

  • Manufacturing: Chemical, textile, electronics, cosmetics
  • Infrastructure: Airports, landfills, refineries, military bases
  • Utilities: Wastewater, groundwater, leachate treatment 

Wherever PFAS shows up in water, PFASER fits in. 

What makes PFASER different

5 FAQs

Frequently asked question

What are PFAS, and why are they called “forever chemicals”?

PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals known for their persistence in the environment and the human body, hence the nickname “forever chemicals’’.

PFAS are found in various products, including non-stick cookware, water-resistant fabrics, firefighting foams, and even in some food packaging. They can also contaminate water sources near industrial sites and landfills.

Exposure to certain PFAS has been linked to health issues such as cancer, liver damage, thyroid disease, and developmental effects in infants. 

PFAS can enter water supplies through industrial discharge, firefighting foam runoff, and leachate from landfills containing PFAS-laden products. 

Certain home filtration systems, such as those using activated carbon or reverse osmosis, can reduce PFAS levels in drinking water. However, these methods may not completely eliminate all PFAS compounds. 

On-site destruction of PFAS, using technologies like electro-oxidation, can prevent the risks associated with transporting hazardous waste and reduce potential environmental contamination. 

Costs vary depending on the technology, scale, and specific application. While some methods may have higher initial investments, they offer long-term savings by effectively eliminating PFAS and reducing liability. 

The PFASER destroys PFAS on-site using patented BDD electrodes and patent-pending perchlorate process. No sludge produced. 

Yes. PFASER treats other recalcitrant contaminants such as ethanol, methanol, acetone, formaldehyde, phenol, ammoniacal nitrogen, to name but a few. It is very powerful at treating many contaminants simultaneously. 

While electro-oxidation is effective for many PFAS compounds, its efficiency can vary depending on the specific PFAS type and water matrix. Ongoing research aims to optimize this technology for broader applications, such as sludge and soils. Long chain PFAS, precursors and some short chain PFAS are destroyed.

Absolutely. From small sites to large industrial hubs, PFASER module scales with your needs. 

Lower than you think. It has a higher capital cost compared to conventional technologies or off-site disposal methods, but a lower operating cost and minimal maintenance. Thus, big savings over time compared to off-side disposal or conventional treatment. 

Several technologies are being developed and implemented to destroy PFAS in water, including: 

  • Electro-Oxidation or Electrochemical Oxidation (EO) (the terms are synonymous): Uses electrical currents to break down PFAS molecules. 
  • Supercritical Water Oxidation (SCWO): Employs high-temperature and high-pressure water to oxidize PFAS. 
  • Plasma Treatment: Utilizes ionized gas to degrade PFAS compounds.  
  • Hydrothermal alkaline treatment (HALT): Uses high-temperature water with alkaline conditions to degrade contaminants like PFAS.  
  • Incineration: Involves burning PFAS at high temperatures to break down and destroy the chemical compounds. 

Cleaner water. Healthier communities.

PFAS contamination isn’t just an operational risk; it’s a human one. PFASER helps protect the people who live and work near high-risk sites by eliminating harmful contaminants before they reach drinking water supplies.
