Seawater Desalination Plants.

Seawater desalination is a process using which dissolved minerals including salts are removed from the seawater. Despite water is a superabundant natural resource on the planet, but still the available clean drinking water is just only 0.3 percent of the world's total amount of water. The source of natural fresh water is limited so sea water can play and is playing important role to meet the drinking water demand. However, the sea water before  use must be treated (desalinated) which is not an easy task. 

Seawater can be desalinated using various techniques and methods. Distillation is a primary technique used for desalination. However, the process is energy intensive. "One t" of drinking water is obtained by using 620 kWh of evaporation enthalpy.

In REVERSE OSMOSIS on the other hand the energy demand can be reduced to 7 kWh. Other method that can be used is electrodialysis (ion exchange). Lot of factors should be considered before choosing an appropriate technology.

Reverse Osmosis accounts for 85% of total installed desalination capacities. Though both thermal process (MSF,& MED) and membrane separation process are used worldwide but now trend is shifting towards membrane separation process.

Desalination Capacity by Country.
Following are the top five countries where maximum desalination plant is located. It is clear that maximum plant is located in middle east as there is maximum crisis of water. The maximum desalination capacity is in Saudi Arabia followed by USA. Generally thermal process is followed in these regions however now due to advancement in membrane technologies they are too gaining popularity and their use is growing with a rapid pace.

We make Seawater Desalination Plants as per specific needs of our customers, capacity ranging from 100 LPH to 1,00,000 LPH.
