Office Water Service Buyer’s Guide – In Most Developed Countries


water deionization processTap water, moreover known as running water, city water or municipal water, is water that is supplied to a tap or valve.

In most developed countries, tap water is considered suitable to drink. While spring water is water that comes directly from an underground source, rather than from a surface level body of water. Spring water often contains most of very similar impurities as tap water, when in reality. In areas where tap water ain’t suitable for drinking, the water can be purified by using a filter or by boiling or distillation. Because spring water is rarely bottled at the underground source, transported by diesel tankers to a distribution center, it usually goes through a purification process similar to that of tap water.

Mineral water is water from a mineral spring that contains certain minerals similar to salts and sulfur compounds. It can often contain similar contaminants to that of tap water. There are a lot of different purification processes that can be used. Purified water is considered to be purer than spring, mineral or tap water. Traditionally, mineral water was bottled at its source. Now look. Today, like spring water, most mineral water is bottled at a distribution center for mass production. Now please pay attention. It is usually effervescent due to gases that are contained within the water. Therefore, the most common include distillation, deionization, and reverse osmosis. In order to meet the legal definition of ‘purified water’, a certain number of impurities must be removed or reduced to low levels.

water deionization processDistilled water is water that is boiled at a high temperature to remove contaminants before drinking.

This purified type water is often referred to as DI water, DIW or deionized water. Being that some contaminants have a high melting point, now this process isn’t effective at removing every contaminant from the water. For instance, deionized water has undergone a chemical process that uses ion exchange resins. The process can remove most inorganic minerals, metals, and chemicals. This process softens the water by exchanging the natural mineral ions with its own ions. Hydrogen and hydroxide ions are exchanged for dissolved minerals and after all recombined to form water. Basically, it can sometimes be confused with demineralized water, that is water that has had lots of its mineral ions removed, just like sodium, calcium, iron, copper, chloride, and sulfate. Another common filtering process is called deionization.



Deionization is known to produce a high purity water, similar to distilled water, by removing dissolved salts and impurities. It can not remove uncharged organic molecules, viruses or bacteria. In this process, external pressure is applied with intention to push the water through a membrane to catch the particles and reverse the natural flow of the solvent, that is why it’s called reverse osmosis. The downside to this process is that it can often remove quite a few of the desirable minerals from the water together with the harmful contaminants. That said, so it is a water purification technology that uses a semipermeable membrane to remove large particles, impurities and contaminants.

In a bottle delivery service, the water is purified at an offsite manufacturing plant, therefore packaged into jugs and shipped to your office.

In some ‘point of use’ coolers, a filtration process using UV light is used to kill contaminants and remove impurities from your water. ‘point of service’ water coolers can tap directly into your water supply, instead of using jugs that are delivered to your business. Although, filtered water is popular in workplace settings since it tastes better than tap water and produces bettertasting coffee or tea.

Point of use service can be more economical and environmentally friendly by taking out the middle man, who is manufacturing and delivering the big plastic jugs. Some suppliers will even offer a countertop pointofuse water service, that is helpful for those offices who have less floor space. It is also a great deal more convenient -you no longer need extra space to store empty jugs and you don’t need to lift, carry and replace the jugs when they are out of water.

You generally pay depending on the general number of bottles you use every month plus the monthly service fee your supplier charges, with bottled water.

Suppliers typically charge a monthly rental fee for a ‘bottle free’ cooler system. The price you ultimately pay gonna be dependent on the size of your office and the quantity of water your employees drink. Of course according to the supplier, is mostly about 6-pluralpluralpluralpluralpluralpluralpluralpluralobvadjobvadjobvadjobvadjobvadjobvadj
