Purified Water

The term “purified water” represents many types of water. Generally, this is water that has had chemicals removed possibly from any one of a variety of different processes. Some of these removal processes are simple and can be found available to consumers in the form of water filters. These filters have the function of seperating some of the impurities and chemicals that may be found in ordinary tap water. Some of the more complex filters are expensive and offer a reverse osmosis technique. This technique helps move chemicals in the water aside yet is able to leave the remaining water without some of the more commonly found chemicals. Interestingly, both distilled water and deionized water are also labeled as “purified.”

Another process of purifying water is distillation. Water distillation usually entails boiling the water which seperates any chemicals present in the process. During the process, water vapor or steam rises from boiling water and is captured in tubes. When cooled, the vapor returns to a liquid state. This process is capable of removing many chemicals from water, since they can’t become a vapor state. Sometimes, water is distilled in this fashion twice.

Deionized water is another form of purified water. The water deionization process is less costly than distillation. Chemicals are added to the water, in this process, and bond to the dissolved salts carried in water. This bonding will remove the chemicals, leaving behind extremely pure water, which is almost bacteria free. This deionizing water process takes less time and less work, but, for human use, it is more likely to find distilled water available in stores rather than deionized water.

A variety of filtration methods and reverse osmosis make up the sum of ways in which you can achieve purified water. Not all methods result in the same quality purified water that can be made from distillation or deionization. Also, some trace elements may not be filtered out using some processes. However, most purified water which is sold for drinking contains lower levels of chemicals than does the average glass of tap water.
