Membrane (RO) Desalination

IDE’s Membrane Desalination Water Treatment and Reverse Osmosis desalination plants are used for treating a wide variety of water compositions, including tap water, brackish water and sea water. These Reverse Osmosis (RO) plants leverage the accumulated know-how and experience that have kept IDE a market leader for the past 45 years.

Through ongoing development of its best-of-class technologies, IDE has been able to continuously increase the desalination capacities of large-scale plants while dramatically reducing their desalinated water costs on long-term BOT contracts. Our success is evident in our progress over the last decade, in which each new plant has delivered higher capacity and lower costs:

Reverse Osmosis Process

When two aqueous solutions of different concentrations are separated by a semi-permeable membrane, water diffuses through the membrane into the concentrated solution in a process called osmosis. The semi-permeable membrane allows water to pass through it, but prevents the passage of salts (ions) and other molecules from the concentrated solution.
The osmotic flow continues until osmotic equilibrium is reached. The resulting pressure differential between the diluted and concentrated solutions is called the osmotic pressure.
When a pressure higher than the osmotic pressure is mechanically applied to the concentrated solution, pure water will flow through the membrane to the diluted solution, leaving dissolved salts and impurities behind. This phenomenon is called reverse osmosis.

The benefits of the IDE solution include:

• Superior reliability and availability
• High quality processed water
• Optimal selection of Reverse Osmosis membranes
• Compact plant design and reduced initial investment
• Low cost desalination with reduced energy consumption
• Short delivery and installation time
• Easily expandable modular design
• Simple operation and easy maintenance
• Minimal environmental pollution
