Carbon filtration is considered one of the relatively cheap and efficient ways of purifying water. Carbon filters themselves are highly touted for their performance, mainly due to their physical characteristics. A single pound of carbon possesses an approximate surface area of about 125 acres, allowing it to absorb a huge amount of pollutants in water. This quality is one of the factors that make carbon filters an important part of many reverse osmosis water filter systems.
Activated carbon filters are also known as activated charcoal filters. The material is charcoal that has been oxygen-treated to make it highly porous with a large surface area—properties that allow it to absorb significant amounts of water contaminants. When water passes over the carbon, pollutants in the water quite literally “stick” to the activated carbon, and effectively get removed from the water.
In a reverse osmosis water filter system from reputable providers like AXEON Water Technologies, carbon filter systems serve as pre- or post-filtration systems, and are especially beneficial in purifying water with high levels of pollutants, or for applications that require high filtration standards. Carbon filters are effective in removing low molecular weight volatile organic compounds (VOCs), including chlorine and its by-products. The Water Quality Association also recognizes carbon filtration’s effectiveness in removing toxic contaminants like arsenic, chromium, and mercury, as well as certain pesticides and industrial solvents.
Carbon filtration as a stand-alone system is very effective. As a component of an RO system, however, the degree of filtration that can be achieved is highly enhanced. This makes an RO system appropriate for various applications, ranging from residential to commercial and industrial. The ability to remove different kinds and levels of contaminants also gives the system much flexibility in use.
RO system providers like AXEON Water Technologies can design a system that’s best suited for your needs. This involves customizing sizes, RO membranes, and filtration systems, depending on the quality of the feed water, as well as the desired quality of the purified water. Regardless of the filtration capabilities of carbon, it cannot be effective if the manufacturer did not use suitable methods, such as in the type of welding used for plastic components. Thus, it is important to work only with suppliers who have a solid reputation in providing quality products and services.
