Desalination


Desalination Systems For Sea and Brackish Waters
LOGO GLOBAL WATERS final103

Desalination refers to any of several processes that remove excess salt and other minerals from water in order to obtain fresh water suitable for animal consumption or irrigation, and if almost all of the salt is removed, for human consumption. (Wikipedia)

What is the difference between seawater and brackish groundwater? The primary difference between these two sources of water is in the dissolved salts content. Seawater contains higher volumes of dissolved salts (from 10,000 milligrams per liter (mg/l) to over 30,000 mg/l of total dissolved solids as opposed to brackish water (1,000 - 10,000 mg/l). The higher the salt content of the water, the higher the pressure needed for the pumps to push water through the membranes, which drive up the energy costs.

With less than 1% of the world’s store of water being fresh and with salt water covering 70% of the Earth’s surface, desalination will become the most prevalent fresh water solution.

The installation of desalination systems in areas where there is water scarcity, provides for additional supply of high quality water to the local drinking supply; allows for the redistribution of current water supply to other areas; there is an increase in agricultural output; further stimulate tourism development and drives higher real estate values.

GWT has designed an efficient and environmentally sensitive water desalination system, the GWT-SW, using up to 50% less energy than similar products in the market, occupies a much smaller footprint and has lower operating costs of around 25% less than other “state of the art” systems.

The efficiencies of the system allows for many cost-effective applications beyond the typical large scale, municipal desalination use, including housing developments - large and small - hotels and resorts and water wholesaling.

For small applications, GWT has developed a 6,000 gallons per day (GWT-SW06) system with the following specifications:

      • Source water:                                    Brackish or Seawater
      • Production rate:                                 6,000 GPD
      • Product Water Quality:                       <500 parts per million of Total Dissolved Solids (With normal                                                                       seawater as feed)
      • Power requirements:                          240 VAC 3 Phase (Single phase is optional)
      • Process type:                                      Reverse Osmosis
      • Feed water flow rate:                          20 Gallons Per Minute
      • Duty Cycle:                                        100%
      • Automatic Controls:                            High Pressure Shut Down and Low Inlet Pressure Shut Down
      • Efficiency:                                          Will produce 1 m3 of potable water using between 2 - 4 kW/H of                                                                   electricity

The GWT-SW model is stackable and comes in 6,000 and 25,000 GPD modules to cover any increase in water demand.

The efficiency in the water production will be determined by the quality of the feed-water.
