Reverse Osmosis and Nanofiltration Pilot

This water treatment process is a membrane separation technique driven by a pressure gradient. Certain molecules (10⁻⁶ to 10⁻⁷ m) and certain ions are retained while solvent molecules pass through. The energies involved are higher than those of processes with similar objectives. Learn about Reverse Osmosis and Nanofiltration Pilot equipment for optimal educational outcomes.. This technique produces a pure solvent and concentrates ions, making it applicable to seawater desalination, water softening, or treatment of water containing heavy metals.

Educational Topics:

• Study of performance as a function of hydraulic parameters around the cartridges
