Reverse Osmosis Design For the Power Generation Industry - Designing Reverse Osmosis Equipment

In order to understand how Reverse Osmosis equipment works, one must look into the physics of osmotic pressure and semipermeable membranes. These simple concepts are at the very heart of Reverse Osmosis design. A semipermeable membrane allows the passage of specific molecules through it. If a concentrated aqueous solution exists on one side of a semipermeable membrane, pure water molecules tend to spontaneously diffuse from the more dilute side of the membrane to the more concentrated side. This is called Osmosis. When, under significant pressure, this process is reversed we have what is known as Reverse Osmosis.
