The oldest method for production of pure water is the thermal method or distillation -water evaporation from the surface and condensation.
Analyse basis has usually been transfer of water in vapour phase with its subsequent condensation. This basic drawback method usually was quite big maintenance electricity costs required to convert water in the steam. In steam process formation gether with water molecules additional solutes could enter the steam as indicated by their volatility. Evaporation has been achieved in a variety of ways.
Shall we consider the distillation.
Due to this difference the water has usually been separated. Notice that when water boiled out, a variety of boiling point impurities is probably higher. Theoretically, they should be free to evaporate. As long as the salt boils at a far way higher temperature, there are practically no salts in the distilled water. And now here’s the question. What’s happening in distillation process? That’s interesting right? Theoretically right after the distillation absolutely pure water has been obtained. Organic substances, which have identic boiling point than that of water usually can slip in distilled water. That said, to eliminate organic poser substances, the water distillers have pre and post water filters. Water molecules have boiling point of 100°C or 212° various substances have unusual boiling points. The substance that boils at a lower temperature evaporates 1st. That said, the substance that boils at a lower temperature evaporates 1-st. In case water contains oil drops they could be looked for likewise in the distillate.
Distillation is used mainly in laboratories and factories, where it is usually required. Reverse osmosis is always widely used in water treatment plants, one and the other indoors and for manufacture of different drinks, bottled water, and all that Distillation has been used mainly in laboratories and factories, where it is always required.
