Water purification

About three Quarters of the earth's surface is covered with liquid water. In vapour form water is also an important constituent of the earth's atmosphere. In combined form water also occurs abundantly in minerals such as gypsum. In addition water occurs in animals and vegetable tissues it constitutes some 70 percent of the human body and over 90 per cent of some vegetables.

The abundance of water in liquid, solid and gaseous state is a matter of common observation. Not only is water the most abundant compound but it is also very important for life. To be sure life would be impossible without water.

From the chemical point of view water has many points of interest, for it enters into chemical reactions which are of fundamental importance. Not only does water react with many substances, but it has also a marked influence upon many chemical reactions.

Since water dissolves a part of nearly everything with which it comes into contact, absolutely pure water does not occur in nature. But for many purposes it is desirable that water should be pure. The purest natural water is rain. It would be wrong, however, to consider it as being really pure. Nor is ground water is pure. It contains a great deal of impurities, which fail to settle, nor do they evaporate with water, which makes their removal difficult.

One of the most important problems is to obtain water sufficiently pure to meet our needs. The choice as to what process is to be used for purification of water depends upon the uses for which it is intended as well as the impurities it contains. Water used for steam boilers should be free from substances that cause corrosion and scale formation. Water for washing should not contain substances that react with soap. When water is to be used for drinking it is necessary that the microbes which it may contain should be killed. To achieve this, water which is to be purified, is thoroughly filtered. Another way to purify water is to boil it.

None of these methods is fit for producing pure water in the chemical sense, since most of the soluble salts are unaffected by the treatment. To remove this and to prepare chemically pure water suitable, for scientific use, we take advantage of the fact that water is easily changed to steam while most of the dissolved substances as already mentioned are not volatile. By condensing the steam we are thus able to remove all impurities except volatile ones. This technique is called distillation. Distilled water has many uses, both in the laboratory and in industry when even small quantities of impurities would be undesirable. Pharmacy is one of the cases where water is used in the preparation of medicines and the traces of salts in solution may produce undesirable results.
