Water Filtration

The number of gallons being flowed through water coolers has nearly doubled in the last half a decade due to the growing concerns about the safety of tap water. This increase alone isn’t directly sourced from offices but also schools, universities and hospitals that are opting to exchange their water coolers for bottle-less, reverse osmosis coolers.

This change is primarily motivated by the fact that standard water coolers that use bottles can provide the perfect breeding ground for high amounts of unhealthy bacteria, which can cause diarrhea and unsettled stomachs. In a study conducted on a Boston University campus which examined their own water coolers, dangerous levels of potentially harmful bacteria were found. Of the ten water coolers that were tested, each contained a count exceeding 2,000 times the government’s recommended quantity, or four times the 500 organism ceiling. These bacteria are not thought to be present when the water is delivered, but rather the dispensers and spigot are thought to be the major cause for concern. When connected to the cooler the bottle is sitting in a contaminated holder thus infecting the clean drinkable water.

Fortunately, a process of reverse osmosis does not have the same amount of bacteria infecting the water. Instead of harboring bacteria reverse osmosis purifies even the dirtiest of water. This process requires pressure to force water through a membrane, leaving the impurities behind. The membrane used is a semi-permeable membrane that separates and removes dissolved solids, pyrogens, submicron colloidal matter, viruses and bacteria from the water. This technique leaves no space for the common bacteria found in today’s drinking water as it removes almost 99% of the total dissolved solids (TDS) and 99% of all bacteria, leaving the user with fresh clean drinkable water. Prices of bottle-less reverse osmosis water coolers cost anywhere from hundreds to thousands of dollars depending on the brand and the various features that are available, but in comparison to bottled water dispensers there are significant advantages that make the cost worth while.
