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

This main drawback method is the very high maintenance electricity costs needed to convert the water into the steam. On p of that, the process basis is the transfer of water in the vapour phase with its subsequent condensation. Usually, in steam process formation with water molecules other solutes can enter the steam conforming to their volatility. Evaporation is achieved in various ways.

Let’s consider the distillation.

The water molecules have the boiling point of 100°C or 212° Other substances have different boiling points. With that said, the substance that boils at a lower temperature evaporates first. Organic substances, which have similar boiling point than that of water can slip in the distilled water. So here’s a question. What’s happening in distillation process? If the water contains the oil drops they can be found also in the distillate. Theoretically after the distillation the absolutely pure water is obtained. It is the substance that boils at a lower temperature evaporates first. When the water has already boiled out, various boiling point impurities is higher. Theoretically, they will begin to evaporate. Besides, to eliminate organic problem substances, the water distillers have pre and post water filters. Now let me tell you something. Because the salt boils at a much higher temperature, there are practically no salts in the distilled water. Fact, since this difference the water is separated.

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