water desalination

Water Desalination Only 3% of the water on earth is fresh. Three-fourths of that fresh water is in the form of ice. As we waste more of our freshwater supply, water desalination will become a big part of our health. Although water desalination is expensive, it is sometimes cheaper than shipping freshwater long distances. Desalted water provides the primary source of municipal supply in many areas of the world, and its use is increasing in the …

…in the future. On the average, a human in the United States uses 70 gallons of water per day. If we continue this, our freshwater supply will be gone. One method that can be easily used is flash distillation. Larger and more efficient facilities are being constructed that will yield well over 30 million liters of desalted water per day. We will never run out of water as long as these new methods are being improved upon.
