The diagram below shows how salt is removed from sea water to make it drinkable.
The diagram illustrates the way in which clean
water
that can be used for drinking is produced from the sea by removing salt.
Overall
, the process consists of 6 stages, beginning with transporting saltwater to pre-treatment and ending with storing drinkable water
.
As can be seen, to begin
with, seawater goes through a pre-treatment filter and undergoes a filtering process. Then
, the filtered water
is through the membrane by high pressure. Meanwhile, impurities and salt that the bigger than the gates membrane are removed and membranes only allow water
molecules to pass. In the subsequent stage,liquid flows to The post-treatment. In addition
, salt water
is filtered in two first steps. The wastewater ( filter backwash and seawater concentrate ) is given back to the sea. In the post-treatment stage, lime, chlorine and fluoride are added water
. In the final step, the filtered water
is placed into storage to prepare for an integrated water
supply system.Submitted by smksalati on
