what is it and what does it do?
What is Desalination?
but with this pro there is a con.. how will it effect the already endangered aquatic animals and their salty habitats?, will it effect humans negatively?
Why do people use Desalination?
Desalination is a way to make sure people have enough water where countries:
-do not have enough freshwater that is easy to get to.
-that are devastated by drought need freshwater.
-rainfall is changed by climate increase or decreases.
-the human population grows faster than already low water supplies water supplies.
How does Desalination work?
- Saltwater is pumped into the desalination plant with a big tube on the ocean floor.
- The saltwater goes through a filtration screen to remove large objects like sand, weeds, and other large objects and then it floats down through filters at the bottom to remove smaller objects in the water
- the salt is removed using a process called reverse osmosis. large amounts of pressure are used to push the seawater through large amounts of filters which is for reverse osmosis, which are like very small screens with minuscule holes so small which makes it fresh drinking water and then pure saltwater concentrate is left.
- The leftover saltwater concentrate is about two times as salty and two degrees warmer than the ocean usually is. This concentrate is returned to the sea through a different large tube that is place on the bottom of the sea or ocean.
- The salt concentrate is mixed into the ocean and returns to its normal levels of saltiness and heat between 164.042-246.063 feet from the outlet tube I even don't know why they do this?
- then everything is supposed to be all back to normal while we aren't seeing that we are changing what we already have.

What do you need for desalination?
- just in California 50,000 gallons of saltwater a day is turned into fresh drinking water
- over 90% of the earths surface is water and 97% of that is salt water only 2% is in gaseous form while 0.9% is solid water and 0.1% is fresh drinking water cool right!?!
- over 50,000 gallons of water fills a pool 40 ft wide 20 feet long and a depth of 9 ft here's a pic it looks small but remember its 9 ft deep
