The Most Competitive Seawater Desalination System

2000, 3000, 5000LPD seawater desalinaiton RO systemThe most competitive desalination system

Competitive price, reliable working performance and long service life.

Treatment capacity: 2ooo to 5ooo liters per day

We designed this cheap desalination system for remote area,  to solve drinking water  at a low cost. Of coz, the system also can be used on boat or for other application, can be customized due to various working condition.

Some facts of desalination

November 29, 2010 Leave a comment
    • It is estimated that some 30% of the world’s irrigated areas suffers from salinity problems and remediation is seen to be very costly.
    • In 2008 there were more than 13,000 desalination plants around the world in 120 countries. They produce some 63.48 million m3/day of freshwater.
    • Global desalination investment total amount up to 24.8 billion us dollars and increased 20% to 30% per year.
    • It is estimated that there total 70 billion us dollar market in future 20 years, and china market share will get a quick increasing.
    • The most important users of desalinated water are in the Middle East, (mainly Saudi Arabia, Kuwait, the United Arab Emirates, Qatar and Bahrain), which uses about 70% of worldwide capacity; and in North Africa (mainly Libya and Algeria), which uses about 6% of worldwide capacity.
    • Saudi Arabia plants take about 24% capacity of world desalination. The biggest desalination plant is JEBEL ALI desalination plant in UAE which  produce 300 million m3/day.

      Seawater desalination

      www.forwardaqua.com
      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.

      Advantages

      ·
      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.
