Water purification generally means freeing water from any kind of impurity it contains, such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water.

#1 A healthy person can drink about three gallons (48 cups) of water per day.

#2 Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.

#3 Much more fresh water is stored under the ground in aquifers than on the earth’s surface.

#4 The total amount of water on the earth is about 326 million cubic miles of water.

#5 The United States uses about 346,000 million gallons of fresh water every day.

#1 At birth, water accounts for approximately 80 percent of an infant’s body weight.

#2 Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain.

#3 Roughly 70 percent of an adult’s body is made up of water.

#4 Water intoxication is most likely to occur during periods of intense athletic performance.

#5 Somewhere between 70 and 75 percent of the earth’s surface is covered with water.
