MULTIMEDIA WATER FILTRATION SYSTEM BY AQUA DEM
Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. Each piece of carbon is designed to provide a large section of surface area, in order to allow contaminants the most possible exposure to the filter media.
One pound (454g) of activated carbon contains a surface area of approximately 100 acres (1 km²/kg). This carbon is generally activated with a positive charge and is designed to attract negatively charged water contaminants. Carbon filtering is commonly used for water purification.Carbon filters are most effective at removing chlorine, sediment, and volatile organic
compounds (VOCs) from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.
Water filters use two different techniques to remove dirt. Physical filtration means straining water to remove larger impurities. Another method of filtering, chemical filtration, involves passing water through an active material that removes impurities chemically as they pass through.
