What Is Distilled Water: Manufacturing Process, Uses, and Benefits

What is distilled water (Freepic)

YOGYAKARTA - Distillation is a water purification method that has been used for a long time, both in households and industries. This method is carried out to obtain very clean and safe water for various purposes. So what is distilled water?

The distillation process works on the basic principle of separating substances based on differences in boiling points. In the context of water, this process involves heating water until it evaporates, then the water vapor is condensed back into a liquid.

With this process, water becomes free from most dirt, minerals, bacteria, and chemicals that do not evaporate with the water. Let's understand what distilled water is, its uses, and advantages.

What is Distilled Water?

Distilled water is water resulting from the distillation process, which is the process of heating water until it evaporates and then cooling the vapor so that it becomes water again. In this way, most of the contaminants that do not evaporate easily will be left in the original container. Meanwhile, the water vapor that turns into a liquid returns to pure water or distilled water.

Distilled water is very pure because it does not contain mineral ions, so it is often referred to as demineralized water. In its use, distilled water is not only used for drinking, but is also used in laboratories, pharmaceutical industries, automotive, and medical devices.

Distilled Water Making Process

The water distillation process consists of several stages, namely:

1. Heating: Raw water is heated in a container until it reaches boiling point (100°C). At this temperature, water begins to evaporate into water vapor.
2. Evaporation: The water vapor that is formed will rise and leave other substances that do not evaporate, such as minerals, salts, heavy metals, and most microorganisms.
3. Condensation: The water vapor that has risen is directed to the cooling channel or condenser. The temperature of the steam is lowered so that it returns to liquid water.
4. Storage: The condensed water is collected in a sterile container. This is called distilled water, pure water without contaminants.

Uses of Distilled Water

Distilled water has many benefits, depending on the field of use. Here are some examples of the uses of distilled water:

• Laboratory: Distilled water is used as a solvent in experiments because it does not contain minerals that can interfere with chemical reactions.
• Medical and Pharmaceutical: Used in the manufacture of drugs, infusion solutions, and sterilization of medical equipment.
• Vehicle Batteries and Radiators: Distilled water is used in car batteries and radiators to avoid scale due to minerals in ordinary water.
• Beauty and Skin Care: Quality skincare products often use distilled water because of its purity and non-irritating properties.
• Consumption: Although safe to drink, distilled water does not contain minerals such as calcium or magnesium, so long-term consumption as the main drinking water needs to be considered carefully.

Advantages and Disadvantages of Distilled Water

Advantages:

• Free from contaminants such as chlorine, lead, mercury, and microorganisms.
• Suitable for technical and medical use.
• Does not leave scale or sediment.

Disadvantages:

• Does not contain minerals that are important for the human body, such as calcium and magnesium.
• The distillation process requires a lot of energy so it is more expensive than other purification methods.
• The taste of water tends to be bland because it does not contain minerals.

Is Distilled Water Safe to Drink?

Technically, distilled water is safe to drink because it does not contain any harmful substances. However, because it does not contain natural electrolytes and minerals, long-term consumption can potentially disrupt the body's electrolyte balance if not accompanied by mineral intake from other sources.

Therefore, although distilled water can be used as an alternative to drinking water, it is advisable not to rely on it as the only source of hydration.

That's a review of what distilled water is and its uses. Distilled water is the result of a water purification process through distillation, which produces pure water without contaminants and minerals. This water is very useful in various sectors, from medical, laboratory, to industry. Also read the reasons why many areas lack clean water.
