More than 2/3rd of the new desalination capacity being installed worldwide is now based on reverse osmosis. In contrast to traditional evaporation-based technologies, no heat energy is required for reverse osmosis. This reduces the cost of desalinated water.

Even in regions where energy costs are relatively low such as the Middle East, reverse osmosis is the preferred technology. Given the right plant design and the right equipment (60 per cent of the total energy consumption is used to power the pumps), nothing can match the reverse osmosis technology, reports Sulzer.

Reverse osmosis use the membrane to act like an extremely fine filter to create drinking water from contaminated water. Pressure is applied to the contaminated water forcing water molecules through the membrane.

Sea Water is not the Only Option.

Desalinated ground water is another potential source, claims Germany Trade & Invest. Texas, Florida and California are leading users of this technology. Seawater desalination is becoming an increasingly significant factor, particularly in California where megaprojects are at the planning stage.

Demand for high-efficiency pumps and rugged membranes continue to increase. Financing for many projects is now provided by public-private partnerships. Executive Director, Association of State Drinking Water Administrators, Jim Taft says that mobile desalination systems have significant potential.

The Demand Increases...

Demand is likely to increase as these systems in the South could help the water industry to manage more frequent periods of drought or temporary supply shortages.
