Pure Water vs Purified Water – Know the Difference
“Pure water” is a term commonly used by all of us in everyday parlance. But it is only meaningful in context, that is, relative to some standard that defines its suitability with respect to a particular end use. The end use might be getting your clothes clean in the laundry or making better coffee. Or increasing the energy efficiency and life of your hot water heater.
“Pure water” suitable for clothes washing might be defined as having less than 1 grain per gallon of calcium and magnesium hardness. In fact, the term “hard water” was originally coined meaning water that was “hard” to wash in. “Pure water” for drinking (or making coffee) might be defined as at least meeting or exceeding the EPA’s drinking water standards.
But in all of the above cases, the water could never be called “pure” in the technical sense, when defined as water that contains abolutely nothing else but H2O. In fact, water that meets the 18.1 mega-ohm standard for ultrapure water in the semiconductor manufacturing industry is generally considered the purest we can get water in real life.
This water is so pure (but not absolutely pure) that it would be corrosive to most plumbing systems or containers we could put it in, and must be continuously recirculated through point of use treatment immediately prior to its use for rinsing computer chips, because it just won’t stay this pure sitting in a container–the water will try to dissolve the container, or absorb gasses from the atmosphere. This degree of purity is sufficient to prevent it from conducting electricity, and hence its utility in rinsing microchips with electric circuits made literally at the molecular level.
Well, you might say “if my water at home was this pure, at least I wouldn’t have to worry about accidentally dropping the hair dryer into the bathtub and electrocuting myself!” On a more serious note though, this water would not be good for the health of most plumbing systems because it would corrode them, and is not considered suitable for drinking, even though it is very “pure.”
The truth is that absolutely pure water doesn’t exist, either in nature, and even when treated with the most advanced technology available to us.
What Does Pure Water Taste Like?
“When you taste something, you’re comparing the taste of that water to the saliva in your mouth,” says Gary Burlingame, who supervises water quality for the Philadelphia Water Department. “The saliva in your mouth is salty.”
Salty saliva bathes your tongue, drenching every one of your thousands of taste buds. It protects you from nasty bacteria, moistens your food, helps you pronounce the word “stalactite” and even lets you know when you might be drinking something bad for you. Like water.
Pure water, that is.
Stripping water down to an ultrapure state makes it unfit for human consumption.
In the world of electronics, manufacturers remove all of the minerals, dissolved gas and dirt particles from water. The result is called ultrapure water, and they use it to clean tiny, sensitive equipment like semiconductors, which are found in computer microchips.
Water molecules have a slight negative charge, which means they’re good at dissolving or pulling other molecules apart. When water is in an ultrapure state, it’s a “super cleaner,” sucking out the tiniest specks of dirt and leaving your computer’s brain squeaky clean.
But if you were to drink ultra-pure water, it would literally drink you back. The moment it came through your lips, it would start leaching valuable minerals from your saliva.
“Your mouth wants potassium, magnesium and other minerals,” says Arthur von Wiesenberger, a professional water taster who’s been running water-tasting competitions for more than 20 years. “It can tell when it’s being stripped.”
Fortunately, pure water is rarely found in nature. Water is constantly moving and passing through rock and soil, picking up minerals and chemicals your body needs as it goes.
Pure Water vs Purified Water
As we’ve seen in the above paragraphs, pure water and purified water are two very different things. Purified water is water which has undergone numerous forms of mechanicals as well as physical filtration, as well as other processes to purify it to a safe point of consumption.
Pure water is used more in medical applications.
