The flow-chart gives information about how the sea water are processed into the drinkable water for consumer.
It is clear that there are four main stages in the production. These include pre-treatment filter, high-pressure membrane filtration, post-treatment with particular materials and storage.
The initial stage of the desalination process begins with pre-treatment filtration, in which salt water goes through filtration to remove larger impurities and particles. Following this, the filtered water is forced through a membrane at high pressure, allowing only water molecules to pass through while effectively blocking salt and other impurities. As a result, desalinated water is separated from the salt. After that, it undergoes post-treatment with lime, chlorine, and fluoride. Finally, the treated water is stored before being integrated into the water supply system, ensuring that it becomes part of the potable water supply.
Additionally, these steps also involve the return of byproducts such as filter backwash and sea water concentrate to the sea.
