Definition of Purified Water

Definition of Purified Water

Purified water undergoes a purification process to remove impurities and contaminants. This process can involve various methods, such as distillation, reverse osmosis, deionization, and carbon filtration.

The impurities and contaminants that are removed during the purification process can include minerals, chemicals, bacteria, viruses, and other pollutants that may be present in the water. Purifying water aims to make it safe and clean for consumption and other uses.

Purified water is often used in various industries, such as pharmaceuticals, cosmetics, and food and beverage production, where the quality and purity of the water are critical. It is also commonly used for drinking, cooking, and other household activities. Therefore, purified water is a high-quality, safe, and clean source, making it suitable for various uses.

Process of Water Purification

Process of Water Purification

The process of water purification is essential for ensuring the safety and quality of drinking water. By understanding the different methods used to purify water, you can decide which method is best for your needs. In the following section, we will briefly review them, so let us continue to read.


Filtration is a process of removing impurities from water by passing it through a porous material. The most common materials used for filtration are sand, gravel, and charcoal. The water is passed through these materials, which trap the impurities and contaminants, leaving the purified water to flow through.


Distillation is the process of boiling water and then condensing the steam back into the water. This process removes impurities and contaminants with a higher boiling point than water. The purified water is collected in a separate container, leaving impurities and contaminants behind.

Reverse Osmosis

Reverse osmosis passes water through a semi-permeable membrane that traps pollutants and contaminants. The water passes through the membrane forcefully under pressure, leaving behind the pollutants and contaminants, which are then flushed away. The purified water is collected in a separate container.

Each of these processes has its advantages and disadvantages. Filtration is simple and inexpensive, but it may not remove all impurities. Distillation is effective at removing contaminants, but it is an energy-intensive process. Reverse osmosis is effective, but it requires a lot of energy and can be expensive to maintain.

Advantages of Purified Water

Drinking purified water has several advantages over different types of water. It can help improve your health, taste better than tap water, and reduce plumbing issues. Here are some benefits of drinking purified water:

Health Benefits

Purified water is free of harmful contaminants and impurities that can affect your health. Drinking purified water can help:

  • Reduce the risk of gastrointestinal diseases
  • Lower the risk of cancer
  • Improve your immune system
  • Promote healthy skin

Taste Improvement

Purified water has a better taste than tap water. It does not contain any chlorine or other chemicals that can affect the taste of water. Purified water is also free of any unpleasant odor or taste that tap water may have.

Reduced Plumbing Issues

Purified water can help reduce plumbing issues. Tap water often contains minerals and other substances that can cause buildup in your pipes and appliances. Purified water can help prevent this buildup, extending the life of your plumbing system and appliances.

Comparison with Other Types of Water

Purified water is the best choice for those who want clean, refreshing, and healthy water. It is free of impurities and contaminants and is safe for consumption.

Tap Water

Tap water is the most common source of drinking water in many households. It comes from municipal water sources and is treated with chemicals to remove impurities and make it safe for consumption, but it can still contain trace amounts of contaminants. Here is a comparison table of purified water and tap water:

Type of WaterPurified WaterTap Water

Spring Water

Spring water is sourced from natural springs and is believed to be a healthier alternative to tap water. It is naturally filtered and is free of chemicals and other contaminants. However, spring water can still contain bacteria and other microorganisms. Here is a comparison table of purified water and spring water:

Distilled Water

Distilled water is produced by boiling water and collecting the steam, which is then condensed back into water. This process removes impurities and minerals, making it virtually pure. However, distilled water can also remove beneficial minerals that are essential for good health. Here is a comparison table of purified water and distilled water:

Potential Drawbacks of Purified Water

Potential Drawbacks of Purified Water

While purified water has advantages, it is important to consider the potential drawbacks before deciding. By weighing the pros and cons, you can make an informed choice about the type of water that is right for you.


One potential drawback of purified water is the cost. Compared to tap water, purified water can be significantly more expensive. This is because of the additional steps required to purify the water, such as reverse osmosis or distillation. If you are on a tight budget, it may not be feasible to purchase purified water regularly.

Environmental Impact

Another potential drawback of purified water is its environmental impact. Purifying water requires energy, contributing to greenhouse gas emissions and climate change.

Additionally, the production and disposal of plastic water bottles can harm the environment. If you are concerned about your carbon footprint, consider using a reusable water bottle and filtering tap water instead of purchasing purified water.


Where can I buy purified water?

You can buy purified water at grocery stores, convenience stores, and online retailers. Look for brands that specifically state that their water is purified through a process such as reverse osmosis or distillation.

What is the difference between purified and spring water?

Purified water goes through a process to remove impurities and contaminants, while spring water comes from a natural source and may contain minerals and other natural substances. Purified water is generally considered safer for drinking, while spring water may have a distinct taste and texture.

Can purified water be used instead of distilled water?

Purified water can be used instead of distilled water for most purposes, but there may be some specific applications where distilled water is preferred. For example, when purity is critical, distilled water is often used in medical settings or laboratory experiments.

Is purified drinking water good for you?

Drinking purified water is generally considered safe and beneficial for your health. It can help remove harmful contaminants and impurities from your body, improving overall health and well-being. However, choosing a reputable brand that uses a reliable purification process is important to ensure the water is safe to drink.


In conclusion, purified water has been treated to remove impurities and contaminants. It is important to note that purified water is not the same as distilled water, which is produced through a different process. Pure water has several advantages, including

  • Improved taste and odor
  • Removal of harmful contaminants and impurities,
  • Consistency in quality and purity

Purified water is widely available in various forms, including bottled water, filtered water, and reverse osmosis water. Choosing a reputable brand or source is important to ensure that the water is properly purified and safe for consumption.
