A team of researchers from the UM6P School of Applied and Engineering Physics has pioneered water desalination technology with Filtration Systems

The introduction of a novel graphene-based device for water filtration. This new concept features two graphene electrodes with nanopores, achieving an unprecedented permeability of 1208 L/h·m²·bar while maintaining a 100% salt rejection rate due to the applied electric field.

The team employed a straightforward method for controlling membrane pore sizes at the nanoscale using argon-plasma magnetron sputtering. This innovative approach demonstrates the tunability of nanopores in graphene, allowing for precise control over membrane properties. Additionally, the system incorporates two types of substrates, SiO₂ and SiC, making the graphene-based membrane more adaptable and practical for large-scale, industrial desalination applications while retaining exceptional desalination performance.

This breakthrough promises to enhance the efficiency and sustainability of water desalination processes, offering a potential solution to global water scarcity issues.
The findings represent a significant step forward in the application of graphene-based technologies for industrial purposes.
