Activated Carbon filter

For small scale water purifiers are installed to prevent formation of minerals on the surface of the electrodes and to remove organics and chlorine from utility water. First the water passes through a 20 micrometer interference ( or ) filter to remove sand and dust particles, second, a charcoal filter () to remove organics and , third stage, a to remove metallic ions.^[] A test can be done before and after the filter for proper functioning on , , , , and

Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 . The particle size will be used as part of the filter description. The efficacy of a carbon filter is also based upon the flow rate regulation. When the water is allowed to flow through the filter at a slower rate, the contaminants are exposed to the filter media for a longer amount of time.

Carbon filters are most effective at removing , , and (VOCs) from water. They are not effective at removing , , and dissolved inorganic compounds.

Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing
