The oldest method for production of pure water is the thermal method or distillation -water evaporation from the surface and condensation.

Then the process basis is the transfer of water in the vapour phase with its subsequent condensation. Eventually, this main drawback method is the very high maintenance electricity costs needed to convert the water into the steam. Remember, in steam process formation together with water molecules other solutes can enter the steam in line with their volatility. Evaporation is achieved in various ways.

Let’s consider the distillation.

And now here’s a question. What’s happening in distillation process? With that said, the water molecules have the boiling point of 100°C or 212° Other substances have different boiling points. The substance that boils at a lower temperature evaporates first. Anyway, when the water has already boiled out, various boiling point impurities is higher. Theoretically, they will begin to evaporate. You should take it into account. The substance that boils at a lower temperature evaporates first. Due to this difference the water is separated. Theoretically after the distillation the absolutely pure water is obtained. Organic substances, that have similar boiling point than that of water can slip in the distilled water. This is the case. If the water contains the oil drops they can be found also in the distillate. As long as the salt boils at a much higher temperature, there arethere’re practically no salts in the distilled water. Then, to eliminate organic problem substances, the water distillers have ‘pre and’ post water filters.

Distillation is used mainly in laboratories and factories, where it is needed. Reverse osmosis is widely used in water treatment plants, both in the premises and for manufacture of various drinks, bottled water, and suchlike Distillation is used mainly in laboratories and factories, where it is needed.
