What is sea water desalination?
In a nutshell, desalination is a process that removes salt and freshwater from salt water. The process can be done using various methods, such as:
– Reverse osmosis
In this article we will look at distillation and reverse osmosis, read on!
Seawater covers almost 70% of the planets surface and represents 97% of the worlds water, so using it to create some supply of freshwater makes sense. There are around 21,000 desalination plants located across 177 countries that generate around one percent of the world’s drinking water. These plants are concentrated in regions such as the middle east because of easy access to the sea. Countries like Saudi Arabia, Kuwait, and the United Arab Emirates have among the largest of the plants.
Sea water desalination in detail.
Desalination is the process of turning salt water from the ocean into freshwater for drinking. On a small scale, the process is distillation of water. It happens through boiling the seawater, collecting the stream and condensing it to liquid form. However, on a large scale, this process is a lot more difficult as it involves large-scale facilities, is energy-intensive and are expensive. Among the most popular technologies used for desalination are:
- Thermal sea water desalination involves the separation of the saline content (salt) by evaporation in distillation systems. To reduce the energy consumption required by the heat, a process called Multiple effect Distillation (MED) is used. It reuses the energy generated during vapor condensation.
- Reverse osmosis desalination happens via the passage of water through a semipermeable membrane. The semipermeable membrane acts as a filter that allows only water molecules to pass and not the large salt molecules. This process is similar to what happens in cells. To maintain the concentration of water and solutes in the body.
