The problem of PFAS and micropollutants

Micropollutants (pharmaceutical residues, endocrine disruptors, pesticides, etc.) and PFAS (per- and polyfluoroalkylated substances) are at the heart of today’s environmental challenges. These emerging pollutants are difficult to eliminate by conventional water treatment processes, due to their chemical stability and persistence in the environment.

To meet these challenges, advanced solutions such as adsorption on activated carbon, in the form of powdered activated carbon (PAC) or microgranular activated carbon (CAG µgrains), are implemented in drinking water treatment plants and wastewater treatment plants (WWTPs), particularly during tertiary or quaternary treatment.

The Sodimate solution for PFAS and micropollutant treatment

At Sodimate, we offer complete, modular systems for the storage, dosing and transfer of activated carbon, whether in powder form (CAP) or in micrograins (CAG µgrains).

Our equipment is designed to meet the specific requirements of water treatment plants and guarantee safe, precise and regular feeding of adsorption processes.

Our equipment for powdered activated carbon (CAP / PAC)

• Activated carbon storage: in silo, big-bag, flobin or bag hopper, depending on product packaging.
• Extraction: mechanical arch breaker system ensures continuous, even extraction of activated carbon, without the formation of bridges.
• Dosing: volumetric or weight-loss feeders for fine adjustment of activated carbon flow.
• Slurry preparation: preparation tank for forming a homogeneous suspension of powdered activated carbon in water.
• Injection: slurry is injected into the process (reactor, decanter, filtration, etc.) via a skid of pumps.

In recent years, this method has been gradually replaced by a simpler, more compact solution: in-line transfer of powdered activated carbon via a hydroejector, enabling CAP to be injected directly without the need for a preparation stage.
