Sure! Here’s the revised version with a focus on where the water is processed during each step, incorporating the suggested terms:
The diagram illustrates the relatively straightforward process of removing salt from seawater to produce potable water. Overall, the system channels seawater through a desalination system, where it undergoes several essential stages within designated containers and facilities to become suitable for consumption.
The process begins with pretreatment filtration, a critical step in which seawater is directed into specialized filtration containers to remove suspended particles like dirt and sand. This is accomplished using a filter backwash system, which redirects the waste material back into the sea. Once pretreated, the water is transferred into a high-pressure filtration unit, where it passes through a membrane. In this unit, the water molecules are separated from salt and other impurities, while the high-salinity concentrate is discharged back into the sea.
After filtration, the water moves into chemical treatment barrels, where substances such as lime, chlorine, and fluoride are added to ensure safety, improve taste, and enhance quality. Finally, the treated water is stored in large reservoirs, ready for distribution through an integrated water supply system.
