Reverse Osmosis (RO) Systems / Nanofiltration Systems
Semi-permeable membrane to remove minerals & dissolved solids from water
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.RO seawater desalination system Process Introduction
