The Importance of Treating PFAS Now

PFAS (per- and polyfluoroalkyl substances), known as “forever pollutants,” are highly resistant synthetic chemical compounds primarily derived from industrial activities. They accumulate in soil and water, posing an increasing environmental and health challenge.

Their persistence is prompting the authorities to step up their vigilance and tighten regulations.

It is essential for industries to implement appropriate treatment solutions:


• To reduce their long-term impact on water resources, ecosystems, and human health.
• To comply with growing, constantly changing and increasingly stringent environmental regulations without investment.

CTP environnement: Proven Expertise in PFAS Treatment

CTP environnement has acquired robust expertise, enabling us to develop and implement an effective and adaptable treatment tailored to the specific needs of industrial sites while ensuring strict compliance with current regulations.

Our expertise is based on dedicated mobile units designed as simple, reliable, and fully monitored solutions.

Our PFAS treatment unit incorporates the following technology:


Fine filtration to reduce suspended solids (SS).
Granular activated carbon (GAC) adsorption to remove dissolved pollutants and long-chain PFAS.
Ion exchange on a resin bed to eliminate short-chain PFAS.

Where problematic pollutants are present, an additional treatment unit can be deployed upstream or downstream as needed.

FAQ

Why Use Our Mobile Technology?

Our PFAS treatment technology offers several unique advantages:

  • Adaptable solution with a mobile, modular unit
    Optimized pre-filtration: In the first stage, pre-filtration eliminates suspended solids (SS) down to 1 µm, while activated carbon eliminates dissolved pollutants. Reducing the initial pollutant load optimizes subsequent treatment stages, enhances overall system performance, and extends the lifespan of the filtration media.
    Targeted efficiency: Our technology combines activated carbon adsorption for long-chain PFAS and ion exchange for short-chain PFAS, effectively trapping the full range of contaminants with removal rates close to 100%.
    Monitored technology: Our system includes real-time monitoring to control and optimize each treatment stage, ensuring optimal performance and immediate adjustments, thus ensuring regulation compliance.

Where Do the Waste Products from Treatment Go?

The components containing concentrated PFAS (polluted media) are sent to a controlled and secure regeneration or disposal facility. This ensures the complete destruction of PFAS without releasing toxic substances, avoiding contamination of the air, soil, and water.

What Are the Mandatory Steps in Each Treatment Design?

  • Identification of a need: Volume, flow rate, nature, and concentration of pollutants.
  • Objective analysis of input data.
  • Proposal of one or more comparative treatment solutions.
  • Cost estimation for industrial-scale installation.
  • On-site implementation.

What Is the Difference Between Long-Chain and Short-Chain PFAS?

The main difference lies in their molecular structure and reaction in the environment:

  • Long-chain PFAS: Composed of more than six carbon atoms, these compounds are bioaccumulative (i.e. they accumulate in living organisms) and persist in the environment. They are effectively captured through adsorption methods such as granular activated carbon (GAC).
  • Short-chain PFAS: Composed of six or fewer carbon atoms, these compounds are just as persistent, but their smaller size makes them harder to trap using conventional adsorption. They require advanced techniques such as ion exchange for effective treatment.

Expert Testimonials

Thibaut, Export Business Developer

"Water pollution from PFAS-containing products has become a major industrial and societal challenge.

Building on our recognized expertise in providing mobile, modular, and scalable solutions, we offer a flexible, turnkey service.

Each proposed treatment is optimized, incorporating physical and/or physico-chemical solutions, equipment, and services aligned with a sustainable life cycle, integrating all our partners.

These robust solutions can be deployed rapidly to meet the needs of manufacturers and local authorities."

Marie, Head of Technical Expertise

"PFAS treatment in effluents is complex to design and implement due to:
The diversity of chemical species classified as PFAS and the variety of effluent types.
Evolving regulations: 20 PFAS species classified in France, 50 worldwide, and more to come.
Very low or yet-to-be-defined regulatory discharge thresholds (often around 0.1 µg/L).
Challenging final disposal requirements.

Several types of technology exist ; thermal, membrane, physical, and/or chemical. Thermal and membrane solutions are not cost-effective in terms of energy and financial sustainability, unless combined with physico-chemical or physical solutions."

Thibault, Director of Innovation & Development

"In the absence of established parameters (variation in effluent composition, discharge or reuse thresholds), the ideal approach is to conduct on-site pilot trials.

Depending on the needs of industrial companies, local authorities, or regulatory authorities, we adopt an iterative and analytical approach to deploying equipment, field measurement devices, and intervention teams capable of defining the most effective PFAS treatment process and achievable limits.

The water quality / energy consumption / waste management balance is always adapted to meet our clients’ expectations."
