Desalination
WEC Projects offers various desalination processes for the removal of dissolved salts, providing process or drinking water from seawater, brackish water or wastewater streams.
Desalination Solutions
Desalination is a process that separates dissolved salts and mineral components from saline water and effluent streams to produce drinking water, process water or pure water for industrial applications. WEC Projects offers various processes in which to achieve this:
Membrane Technology (Reverse Osmosis)
Reverse osmosis membranes allow clean water to permeate through, while salts are retained, much like a fine sieve, from sea water, brackish water or groundwater, and wastewater
Thermal Evaporation
Thermal evaporators are used to boil highly saline and complex wastewater, thereby efficiently and affordably converting the water-based portion of wastes to water vapour to produce condensate, while leaving the contaminants behind. This process is mainly used in industrial applications to produce highly pure water as a resource and to concentrate waste streams for more manageable and cost-efficient disposal.
Ion-Exchange technology
This process uses synthetic resins which adsorb ions or dissolved salts onto the resin. Salts are thereby removed from water (de-ionisation) allowing highly purified product water to be used for specific industrial applications.
Benefits of Desalination
- Drinking water -from seawater, or brackish water or where water is scarce
- Compliance – with discharge and municipal standards
- Resource recovery – such as water for reuse, or even recovering precious metals such as nickel and copper.
