Seawater desalination
The fresh water supply is becoming an very important problem for many area, someone even forecast that it will be next strategical resource after the oil.

As an additional water supply solution, seawater desalination have been increasing very quickly in last 20 years, and the the desalination cost is low enough for scale use due to technology development.

Reverse Osmosis desalination
Water from a pressurized saline solution
is separated from the dissolved salts by flowing through a
water-permeable membrane. The permeate (the liquid flowing through the
membrane) is encouraged to flow through the membrane by the pressure
differential created between the pressurized feedwater and the product
water, which is at near-atmospheric pressure. The remaining feedwater
continues through the pressurized side of the reactor as brine. No
heating or phase change takes place. The major energy requirement is for
the initial pressurization of the feedwater. For brackish water
desalination the operating pressures range from 250 to 400 psi, and for
seawater desalination from 800 to 1 000 psi.


The processing system is simple; the only complicating factor is
finding or producing a clean supply of feedwater to minimize the need
for frequent cleaning of the membrane.

Systems may be assembled from prepackaged modules to produce a supply of
product water ranging from a few liters per day to 750 000 l/day for
brackish water, and to 400 000 l/day for seawater; the modular system
allows for high mobility, making RO plants ideal for emergency water
supply use.

· Installation costs are low.

· RO plants have a very high space/production capacity ratio, ranging from 25 000 to 60 000 l/day/m2.

· Low maintenance, nonmetallic materials are used in construction.

· Energy use to process brackish water ranges from 1 to 3 kWh per 1 0001 of product water.

· RO technologies can make use of use an almost unlimited and reliable water source, the sea.

· RO technologies can be used to remove organic and inorganic contaminants.

· Aside from the need to dispose of the brine, RO has a negligible environmental impact.

· The technology makes minimal use of chemicals.
