DepolluSON – Magnetic Nanoparticles for Rapid and Selective Effluent Purification

At SON, we have developed DepolluSON, a cutting-edge solution for industrial and environmental depollution based on functionalized magnetic nanoparticles.

Our technology leverages a bottom-up soft chemistry approach, enabling the design of nanoparticles with tailored surface functionalities that selectively bind to toxic or critical metals (heavy, rare, or radioactive).

How it works:

1. Injection of functionalized nanoparticles into the wastewater stream.

2. Selective binding of pollutants through surface chemistry.

3. Ultra-fast recovery by external magnetic field, without chemical additives.

4. Discharge of purified water, ready for reuse in industrial processes.

Key benefits:

• Ultra-fast: over 90% pollutant removal in under 5 minutes.

• Highly selective: efficient capture of toxic and strategic metals (Ni, Cd, Pb, U, etc.).

• Eco-friendly: low-energy, clean process with no secondary pollution.

• Scalable: from lab-scale validation to full industrial deployment.

DepolluSON has already demonstrated outstanding chelation rates across a wide range of metals, proving its potential as a game-changer for water treatment and effluent management.

We are now seeking industrial and R&D partners to validate the technology in real operational environments, co-develop tailored solutions, and accelerate its large-scale adoption for a cleaner and more sustainable future.
