Purified water is water that has undergone a physical process to remove impurities. To meet the legal definition of “purified water”, water impurities must be removed or reduced to extremely low levels. The contaminants in purified water are removed to such a degree that they can only be measured in parts per billion (ppb) or parts per trillion (ppt) if they are still present in the water at all. Purified water represents the purest available form of bottled water on the market and has seen a surge in popularity among bottled water drinkers as more and more people seek purity. In fact purified water now represents the fastest growing segment of the bottled water industry.

-Methods of Water Purification?

There are several methods that can be used to purify مياة مايلز water Perhaps the oldest purification method is the process of distillation. Distillation involves boiling water and then collecting the condensed steam into a clean container. The pure water is separated from the solid contaminants which are left behind. Distillation produces very pure water but there is the opportunity for some contaminants to end up in the finished product if their boiling point is less or equal to that of the water Another drawback of distillation is that it can be very energy intensive in order to heat the water When done on a large scale such as would be required for mass production of bottled water distillation is not the most environmentally friendly process.

Deionization represents another method of water purification. Deionization is the process of removing mineral ions from water The actual process of deionization utilizes specially manufactured ion exchange resins to bind and filter out the mineral salts within the source water After the deionization process has been completed the resulting water is of very high purity that is similar to distilled water However, deionization does leave open the possibility of other contaminants making it though the process. Deionization does not significantly remove uncharged organic molecules, viruses or bacteria so while mineral content is removed other undesirable impurities can make it into the finished product.

Reverse osmosis is one of the newest and most energy efficient techniques of water purification. With reverse osmosis, high pressure is used to force source water across a membrane while the impurities in the water are left behind. The high pressure exerted forces the impurities to become concentrated on one side of the membrane while only the pure water is able to cross the membrane. This is an extremely effective purification method if the reverse osmosis system is set up with multiple membranes to remove impurities down to the atomic and molecular level. Although, reverse osmosis is an extremely powerful purification method, it is best used as one step in a multiple stage system using other purification methods such as micron sediment filtration, ion exchange/deionization, activated carbon and ultraviolet disinfection.

-Where can you find Purified Water?

When seeking purified water it is best to look for water that has been purified by a multi-stage purification system. Ideally you will want water purified using a combination of techniques including but not limited to reverse osmosis. In some cases you can find purified water in your local grocery store however it is often only available in single serve bottles. For larger quantities it is best to contact a local bottled water delivery company in your area to have the purified water delivered right to your home or office.
