his is the dictionary version of what distillation is—the evaporation and subsequent collection of a liquid by condensation as a means of purification.

The distillation process
Distilled water is water that’s turned into vapor and condensed elsewhere into “pure” water, leaving the vast majority if not all of its impurities behind. It may incorporate filtration to reduce any potential carry-over of contaminants as well as monitors to indicate all is in proper working order. In a well designed and maintained distillation system, treated water is relatively pure and free of contaminants (see Table 1).

As such, distillation comes closest to the process Mother Nature uses in the natural cycle of evaporation, precipitation and condensation (see Figure 1). The sun heats water from oceans, rivers, lakes, etc. The water vapor then evaporates into the heavens and is captured in the bodies of clouds. As the clouds cool, they release the water as a form of precipitation.

Efficient and reliable are two terms commonly used to describe distillation. Water distillation will significantly reduce bacteria, herbicides and pesticides. Chlorine, nitrates, fluorides, ammonia, aluminum, arsenic, copper, iron, mercury, radium and asbestos are also among the list of impurities left largely behind after the distillation process is done. Plus, distillation normally removes 99 percent of dissolved minerals in water.

Minerals from food
Bear in mind, water is an unreliable source of minerals for bodily intake. These minerals are inorganic, which some assert the body has difficulty absorbing. It’s generally recognized that the vast majority of mineral uptake comes from the food we eat, not the water we drink. These mineral sources are organic and readily assimilated by the body for good health.

Distillation units or distillers fundamentally copy the original process of Mother Nature of purifying water. Most modern distillers are of high quality and stand up very well over extended periods of use. Some last up to 30 years! Distillers work very well at any total dissolved solids (TDS) level and are almost a must at very high levels.

Some advantages of having a distiller in your home are:

  • It easily and efficiently removes impurities.
  • It doesn’t rely principally on physical barriers that could fail and lead to carry-over of impurities into the treated water.
  • It always produces a high quality of water for a long period of time, if not the lifetime of the unit.
  • For most, it has low maintenance.
  • It’s easily disinfected when treating water containing bacteria.
  • It offers control of the water quality you consume vs. bottled water.

For anyone wishing to have water that’s pure and of high quality, distilled water is a good choice. A suggestion to shop around and become informed of all of the different forms or processes with which water can be “purified” is very important so that when the decision is made, the final choice is a wise one. It’s also very important when considering buying any kind of water treatment equipment to familiarize yourself and your customers with its maintenance requirements, as this may affect the total purchase price, quality of water, and operating expense over a long period of time. Certifications ensuring that the required standards are met can also play a factor in choosing the “right” process of water purification for every consumer of “pure” water as well as the unit’s overall cost. It should be stressed, however, that such a premium offers customers better assurance the technology is effective at meeting any aesthetic and/or health claims made by the manufacturer.

Consumers always decide to purchase a home water treatment device based on what they perceive as the best water treatment available. All manufacturers and retailers, when marketing their product, will confirm their product is the “best choice” when it comes to treating water. Research and general information gathering should provide anyone the required knowledge on which to base a final decision before purchasing the required water treatment process. Frequently, distillation is the most practical choice.
