WATER FILTRATION SYSTEM WITH ACTIVATED CARBON AND ZEOLITE
摘要
<p>In one embodiment the invention relates to a filter media for removal of contaminants from water comprising aluminium coated granular activated carbon and granular zeolite. Another embodiment relates to a method of producing aluminium coated granular activated carbon comprising exposing granular activated carbon to an aqueous solution comprising one or more aluminium salts which is acidified to a pH of between about 5 and about 6.8, removing the aqueous solution and washing and drying the aluminium coated granular activated carbon that is produced. Further embodiments relate to: a filter system for removal of contaminants from water comprising (i) a middle zone comprising granular activated carbon and granular zeolite and (ii) a lower barrier zone comprising screening material, wherein the system allows a flow rate of water there through of from about 0.5Lsec-1m-2 to about 10Lsec-1m-2; a cartridge containing the filter system and related methods of removing contaminants from water.</p>
