Reverse Osmosis (RO) Systems / Nanofiltration Systems

Reverse osmosis (RO) and Nanofiltration (NF) membranes are commonly used as a filtration method to remove many types of dissolved solids (large molecules and ions) from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
