Hardly any water supply comes as pure and safe. If you can find a sample that is so pure you would not need to have it treated, you are one lucky man. But the odds of that happening are beyond imagination. There is a good reason why the world needs water treatment and purification facilities, and there is a reason why water manufacturing companies are doing their business. People need safe drinking water; different companies need pure distilled water; and human civilization is not going to be the same if we did not learn how to purify our own water.
Water is one of nature’s important solvents, that organic systems would not be the way they are if water were not available. But it flows through rivers and streams and sits in lakes and oceans, with all the sediments, minerals, organic matter, and all sorts of impurities. While nature continues to manufacture impure water for its own sake, to humans, this kind of liquid is of little value. You cannot drink seawater; you cannot fill your laundry machine with water coming from most streams; and today’s rainwater is not that safe too.
One of the ways to treat the liquid is through distilled water that uses the simple principles of evaporation and condensation and the kind of processes nature does quite efficiently. Humans, however, enhance the process using sophisticated equipment to come up with water that is of high purity. When we speak of pure water, we mean water that has no minerals, bacteria, and any contamination. The treatment process is stringent and its cost is high. This high cost is then transferred to the price of the distillate water, so wonder no more if distilled water may be inconveniently priced.
Contrary to a popular misconception, distilled water does not leach your body of minerals and nutrients. There was a supposition that drinking of water that lacks minerals will drain the body of nutrients, but this is not true. According to most experts, distilled water has nothing to do with mineral depletion in humans because it is not a source of minerals that a shift from regular water to distilled pure water would cause significant mineral loss and nutrient leaching. The speculations were absurd.
Distilled water is often compared to water distiller which is another kind of pure water. Both types of water do not contain ions but they differ in the manner of treatment. Distillation, as mentioned earlier, uses equipment that heats water to turn it to steam, leaving solid impurities behind, and the condensing pure distillate is then collected. Deionization is the process of passing already filtered water through ion-exchange resin beds to remove ions like sodium, carbonates, chloride, magnesium, and calcium. Essentially, the chemical nature of distilled and deionized water is the same.
Water distillation facilities produces water for general public use and, more importantly, for companies and industries involved in pharmaceutical products, food manufacture and processing, chemical manufacturing, and industrial cleanup services. In chemical laboratories, such type of water is relevant as a solvent vessel for preparation of solutions. This purified water is also used in rinsing laboratory apparatuses because they efficiently clean without leaving scales.
