Desalination B-)

Process That Removes Minerals From Saline Water.

MY PROJECT (DESCRIPTION)

  • Wood --> Prevents clean water from evaporating and going back into the desalination process
  • Cup--> Catches the clean water and stores it
  • Foil--> Has a slant it the middle, so the water would hit the cold surface, condense and fall into the cup under it
  • Ice--> cools the foil and make a COLD surface for the vapor to condense on

Problem with the Design

  • requires huge amounts of ice in order to produce more than have of the clean water
  • The wood absorbs some of the water, thus adding water to the experiment

Pros about the Design

  • IT WORKS!!! REALLY WELL!
  • OUT OF 200 ML IT GATHERED MORE THAN 100 ML, ABOUT 115 ML!!!!
  • REQUIRES LITTLE EFFORT TO CREATE!!!

Phases

The major process necessary for Desalination is evaporation, where liquid water gains heat energy and vaporizes, leaving behind all toxins. Then the vapor hits a cold surface, and loses much of its heat energy, causing it to condense and fall, pure.

Fun Facts

Some 80 percent of domestic water use in Israeli cities comes from desalinated water.

There are about 15,000 plants producing desalinated water, most in the Middle East and North Africa—the largest is in Saudi Arabia.

Desalinated water typically costs about $2,000 an acre foot — roughly the amount of water a family of five uses in a year.
