The diagram below shows how salt is removed from seawater to make it drinkable. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Sample 1 The Diagram Below Shows how Salt Is Removed from Seawater to Make It Drinkable
The diagram depicts the various stages of removing salt from seawater in order to make it drinkable.
To begin, a water intake transports saltwater from the sea to a pretreatment filter. Filter backwash is removed and returned to the sea as a result of this. The water is then forced through a membrane at high pressure, allowing only water molecules to pass through while stopping salt and other pollutants, and the seawater concentrate is returned to the sea.
After that, the water is treated with chemicals like lime, chlorine, and fluoride to make it drinkable. It is then transferred to a storage facility before being released to the public via a water distribution system.
To summarise, because the hazardous elements, as well as the salt, are removed, the water produced by this method is pure and drinkable.
Sample 2 The Diagram Below Shows how Salt Is Removed from Seawater to Make It Drinkable
The artist’s impression below illustrates the process of extracting sodium from aqua for consumption.
Overall, it shows that aqua from sea move to saltwater intake, then keep going to pretreatment filter some divert to filter backwash then join flow to return to the sea. Although some diverted, the majority moves to high pressure, which the call water force via membrane at high pressure some dropped sharply to seawater concentrate while some keeps flowing to post-treatment with lime, chlorine, and fluoride then to storage.
From the reservoir to the integrated water supply system, then finally impurities, salt, and water molecules are separated.
To summarise, seawater needs to be filtered and treated with materials in order for it to be safe for people to drink.
