Boiling Water to make it safe – Part 2

Science tube boilBoiling is often confused with distilling, or distillation. Let’s hammer out the difference here in part 2. Distillation requires boiling, true enough, but it is not the water in the boiling pot, container or bowl that becomes distilled……

Instead, it is the steam that is the purified water. In a distillation apparatus a liquid is boiled, and then a collection tube, called a condenser, is used to collect the steam, sometimes the condenser tube has an outer compartment to run cool air or water through. This cooling brings the steam back down to a “condensing” temperature, the water runs down the tube, away from the boiling pot, and into another, clean collecting pot. The water in this pot is said to be distilled.

Distilled water thought by most of us to be the cleanest, most pure water on earth, but the truth is, while it is very clean water, and while it is virtually sterile/bacteria free, and while it is very safe for human consumption and even most medical procedures, many industries require water that is 10 times more pure than distilled water.

Now, boil those ideas for a bit. See you in part 3

  1. Distiller water is not preferred for Drinking and it is highly corrosive for transport by metallic pipes. It should be fortified with essential salts.

    1. Dear Subbier,

      thank you so much for taking the time to offer up a comment. I hope you will subscribe to my e-mail list and be a frequent visitor. Your comments on distilled water, while not exactly addressing any points I was making, do open up a nice topic of conversation. Single distilled water achieves an average purity of about 200,000 ohms per cm squared, resistance. Water at this quality will not damage copper pipes. It is very equivalent to RO water and is still somewhat passive.

      Some distillation equipment can produce water in excess of this quality and you are correct, that water would be corrosive to metal pipes. In addition, regular distilled water could not be used in an existing municipality for a couple reasons. It is indeed corrosive another to dissolve the years of calcium scale build up inside the pipes. This scale actually helps prevent old pipes form springing leaks. Also, and most important, it is too expensive to distill water. It is just not economical as a major drinking water purification method. Distilled water is of course, perfectly fine to drink.
