Carbon Block Water Filters

Drinking water can be contaminated due to many sources; some include community landfills, agricultural runoff, polluted runoff and hazardous wastes as byproducts of manufacturing. Leaks of pollutants such as gasoline and leaking underground storage tanks can also cause water to be contaminated. Because of all these contamination sources, the use of water filters is highly recommended.

Carbon block water filters are used to remove contaminants from your drinking water without removing the healthful, natural minerals. These filters combine processes such as mechanical filtration, electrokinetic adsorption and physical adsorption in order to reduce contaminants effectively.

In mechanical filtration, water passes through a graded density-5 micron pre-filter that traps sand, dirt and other particles that can affect the odor, taste and overall appearance of the water. After this, water then passes through a highly compacted solid carbon block. Here, direct mechanical interception of particles occurs.

Next to mechanical filtration is electrokinetic adsorption. In this process, water passes through a graded density prefilter that acquires a positive molecular charge. Here, the media fibers will electrokinetically attract charged colloidal particles. These particles are too small and can’t be drained by mechanical filtration alone.

Finally, the process of physical adsorption reduces all the aesthetic contaminants and health-related contaminants. A carbon block filter media is engineered so that the contaminants in water will be decreased.

These are the three main processes involved in filtering water through the use of carbon block water filters. Even though these filters are effective at reducing contaminants, it is still highly recommended that they be replaced annually or when they become saturated with bad tastes and odors. Aside from this, replacement is also necessary when the carbon block water filter’s rated capacity is reached and the flow rate diminishes.
