Reverse Osmosis Water Filtration Systems
Reverse osmosis water filtration systems entered the market several years ago now and were heralded as an incredible leap for home water filtration. While it’s true that these kinds of filters can work beautifully for resolving some water quality issues, you should understand the manner in which they work in order to decide if a reverse osmosis filter will meet your specific needs.
Understanding Reverse Osmosis
Osmosis is a process through which a pure liquid is transformed into a solution by the addition of another substance, like when water is contaminated. Reverse osmosis then is the process through which a solution is transformed into a pure liquid. Reverse osmosis water filtration systems are able to remove most contaminants, including heavy metals, minerals, sediment, salt, microbes, bacteria, chemicals and cysts. Through the use of a reverse osmosis system with the appropriate filters, you can capture and eliminate most any contaminant, ensuring the production of pure and safe drinking water. Like with any water filtration system that is designed to purify water, a reverse osmosis system will need to be multi-staged. In other words, if you need the system to remove a range of contaminants, it must contain multiple filters capable of capturing the specific kinds of contaminants in the water supply. Some contaminants can only be eliminated with a solid carbon filter, for example, while others can be captured by a sediment membrane filter. The most effective reverse osmosis systems will feature more than the standard four to six filtration stages seen with other multi-staged systems. In fact, super efficient systems may use as many as 17 stages for filtering water, all driven by the high pressure reverse osmosis process.
Commercial Reverse Osmosis Systems
Reverse osmosis is such an effective water purification process that its commercial applications are extensive. Systems using reverse osmosis provide pure water for the pharmaceutical industry, manufacturing plants, printing businesses, and even convert ocean water into pure drinking water through large scale water treatment plants found throughout the world.
Home Water Filtration Systems
Reverse osmosis water filtration systems for home use provide the same benefits of commercial systems only on a smaller scale and through a more compact system. Each unit contains a series of filter cartridges as well as a pressure tank in which water is stored. Some systems even combine reverse osmosis with ultraviolet purification technologies to ensure the purest and safest drinking water possible. Because reverse osmosis water filtration systems have more stages and because they require multiple cartridges, storage tanks and pressurization mechanisms, there are no faucet mount models or pitcher dispensers available. There are some very compact under the sink models to choose from and countertop systems available as well, in addition to whole house reverse osmosis systems which can be installed.
