Europe tightens PFAS limits in drinking water, requiring the adoption of advanced treatment technologies

Feb 10, 2026

The entry into force of new mandatory limits for PFAS in drinking water across Europe since January 2026 is marking a turning point in the water treatment sector. To ensure their removal from water, Salher offers its range of activated carbon filtration solutions and reverse osmosis systems.

Per- and polyfluoroalkyl substances, known as PFAS, have become a top priority on the European regulatory agenda due to their environmental persistence and potential risks to human health. This new regulatory landscape is driving the adoption of advanced drinking water treatment technologies.

This involves implementing advanced technologies for the removal and monitoring of emerging contaminants, as well as upgrading existing water treatment facilities to guarantee public health safety and the protection of water resources.

What are PFAS and why do they represent a challenge for water treatment?

PFAS are chemical compounds widely used in industrial processes and consumer products because of their resistance to heat, water, and grease. However, their high chemical stability makes them extremely persistent in the environment, which has led to them being referred to as “forever chemicals”.

Their presence in surface water, groundwater, and distribution networks poses new technical challenges for drinking water operators, municipalities, and industries, which must implement more advanced treatment processes to comply with the new parametric values established by European regulations.

Salher activated carbon filtration and reverse osmosis solutions: key technologies for PFAS removal in municipal and industrial drinking water systems

Activated carbon filtration systems are among the most widely used technologies for removing persistent organic compounds from drinking water. Their adsorption capacity helps reduce the concentration of certain PFAS present in water.

Salher’s activated carbon solutions stand out for:

  1. High efficiency in the removal of organic contaminants
  2. Modular design adaptable to new or existing installations
  3. Easy integration into drinking water treatment processes
  4. Optimized operational and maintenance costs

This type of treatment is particularly effective as a polishing or advanced treatment stage in municipal and industrial systems.

Reverse osmosis is one of the most effective technologies for removing dissolved substances that are difficult to treat, including PFAS.

Salher’s reverse osmosis systems achieve high water quality standards for drinking water applications, industrial processes, and reuse, offering:

  • High rejection rates of emerging contaminants

  • Optimised energy efficiency

  • Advanced automation and process control

  • Adaptation to different water qualities and flow requirements
