Water desalination

The major technologies in the field of water desalination include:

  • Reverse osmosis
  • Ion exchange
  • Thermal processes such as MSF (multi-stage flash distillation) and MED (multiple-effect distillation)

The most economical and popular technology to desalinate seawater and brackish water is reverse osmosis. By continuously developing this technique over recent years, it has been possible to reduce energy consumption to a minimum, enabling a significant reduction in water production costs.

While the method of ion exchange is suitable for acquiring completely desalinated water from low-mineral drinking water (such as for industrial purposes), it cannot be used to desalinate seawater and brackish water. In contrast, the thermal methods are primarily suited to desalinating seawater, although they are relatively expensive and involve a high energy consumption.

Our seawater and brackish water desalination systems exclusively function according to the principle of reverse osmosis. In special cases, such as a demand for process water, reverse osmosis can be supplemented with an ion exchanger. This makes it possible to even produce fully desalinated water from seawater.
