Oldest method for production of pure water is thermal method or distillation -water evaporation from surface and condensation.
The sort out basis has been the transfer of water in vapour phase with its subsequent condensation. Usually, in steam process formation with water molecules additional solutes may enter steam as indicated by the volatility. For instance, evaporation always was achieved in numerous ways. Notice, this primary drawback method has been the extremely lofty maintenance electricity costs essential to convert the water in the steam.
We need to consider the distillation.
To eliminate organic poser substances, water distillers have preand post water filters. Needless to say, organic substances, which have identic boiling point than that of water usually can slip in the distilled water. When water has boiled out, different boiling point impurities has probably been higher. Theoretically, they shall be free to evaporate. Substance that boils at a lower temperature evaporates 1-st. As long as the salt boils at a far way higher temperature, there were usually practically no salts in distilled water. Substance that boils at a lower temperature evaporates 1-st. Due to this difference the water is separated. The actual question is. What’s happening in distillation process? Water molecules have boiling point of 100°C or 212° various substances have special boiling points. Theoretically after the distillation absolutely pure water was usually obtained. Now let me tell you something. When water contains the oil drops they may be searched for in distillate.
Distillation probably was used mainly in laboratories and factories, where it was probably required. Reverse osmosis has probably been widely used in water treatment plants, one and the other in the apartments and for manufacture of a variety of drinks, bottled water, and stuff Distillation is usually used mainly in laboratories and factories, where it always was necessary.
