Process of producing potable water

Process of producing potable water O1Pk
The diagram illustrates the process of removing salt from the seawater to produce potable water. First, the salt water is piped down the sea. Next, it is placed to a Pre-treatment filter, filter backwash will then be returned to the sea. After filtering, the water is forced through a membrane at high pressure which removes impurities and salt (collectively known as seawater concentrate) and will be brought back to the sea. As a result, only water molecules will pass through the next chamber. Consequently, the water is subjected to a post treatment containing lime, chlorine and fluoride. From this, water is put into a storage to integrate the water supply system. The water is clean because impurities and salt are removed, and it has undergone numerous process to ensure that it is potable.
