15 Facts About Purified water

Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use.

Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities.

Purified water is usually produced by the purification of drinking water or ground water.

The Purified water is "softened" by exchanging poorly soluble divalent cations with the soluble cation.

Purified water is suitable for many applications, including autoclaves, hand-pieces, laboratory testing, laser cutting, and automotive use.

The microbiological content of the Purified water is of importance and the Purified water must be regularly monitored and tested to show that it remains within microbiological control.

Purified water is used in the commercial beverage industry as the primary ingredient of any given trademarked bottling formula, in order to maintain critical consistency of taste, clarity, and color.

For example, Purified water that is being used for molecular-biology experiments needs to be DNase or RNase-free, which requires special additional treatment or functional testing.

Deionized Purified water should be re-mineralized before use in aquaria since it lacks many macro- and micro-nutrients needed by plants and fish.

Deionized Purified water is very often used as an ingredient in many cosmetics and pharmaceuticals.

The lack of impurity in the Purified water means that the system stays clean and prevents a buildup of bacteria and algae.

However, deionized Purified water has been known to cause cracks in brass and copper fittings.

Deionized Purified water is used in Purified water-fog fire-extinguishing systems used in sensitive environments, such as where high-voltage electrical and sensitive electronic equipment is used.

The extremely fine mist produced takes the heat out of fire rapidly, and the fine droplets of Purified water are nonconducting and are less likely to damage sensitive equipment.

Deionized Purified water is inherently acidic, and contaminants rapidly supply ions, thus re-ionizing the Purified water.
