Water Distiller- Principle, Parts, Types, Uses, Examples


Water is essential for life, but not all water is safe to drink. Tap water may contain various contaminants, such as bacteria, viruses, heavy metals, fluoride, chlorine, pesticides, and other harmful substances. These contaminants can pose health risks and affect the taste and quality of water. Therefore, many people seek ways to purify their water and make it suitable for drinking, cooking, and other uses.

One of the methods to produce purified water is water distillation. A water distiller is a special equipment designed to produce contaminant-free water by transforming water into vapor before condensing into a liquid state. Water distillers replicate the Earth’s natural filtration process to produce water of unmatched purity .

Water distillers work by boiling water and collecting the steam that rises from it. The steam leaves behind most of the impurities that are present in the water, such as dissolved salts, minerals, chemicals, and microorganisms. The steam then passes through a condenser, where it is cooled and turned back into liquid water. The distilled water is then collected in a storage tank or a container .

Water distillers can produce purified water for various applications, such as:

  • Drinking and cooking: Distilled water is free of contaminants that can affect the health and taste of water. Distilled water can also prevent the formation of scale and mineral deposits in appliances that use water, such as coffee makers and kettles.
  • Medical and scientific purposes: Distilled water is used in laboratories, clinics, hospitals, and pharmacies for experiments, sterilization, cleaning, and preparation of solutions and medicines. Distilled water is also used in autoclaves, which are devices that use high-pressure steam to sterilize medical instruments .
  • Industrial and commercial uses: Distilled water is used in various industries that require high-quality water, such as food and beverage production, cosmetics manufacturing, chemical processing, electronics fabrication, and power generation. Distilled water is also used in batteries, cooling systems, humidifiers, steam irons, and aquariums .

Water distillers are available in different sizes and types, depending on the capacity and purpose of use. Some water distillers are small and portable units that can be placed on a countertop or a table. These units can produce one or a few gallons of distilled water per day. Other water distillers are large and automatic systems that can be connected to a water source and produce hundreds or thousands of gallons of distilled water per day.

Water distillation is one of the oldest and most effective methods of water purification. It can remove almost all contaminants from water and produce pure and safe water for various uses. However, water distillation also has some limitations and drawbacks, such as high energy consumption, slow production rate, loss of beneficial minerals, and bland taste. Therefore, it is important to weigh the pros and cons of using a water distiller before deciding to buy one .
