1. CARBON FILTERING NADIRA ADAWEIAH BT JAMALUDDIN 55102215018

2. VIEWS Uses a bed of activated carbon By chemical adsorption and catalyst reduction 2 types of carbon filters use in filtration industry : carbon block filter : granular activated filter

3. ACTIVATED CARBON FILTER To adsorb chlorine, organics, tri-halo methane (THM), taste, odor and color charcoal that has been treated with oxygen Highly porous material Provide larger surface area

4. Working principle Adsorption process and catalyst reduction Contaminants attract and adsorb onto carbon surface Effeciency of adsorption influenced by the carbon characteristics and contaminants characteristics

5. CARBON BLOCK FILTER VS GRANULAR ACTIVATED FILTER Carbon block filter Granular activated filter Solid block of carbon Loose granular of carbon Allow water contact with carbon for longer period Less contact of water with granular activated carbon particle High efficiency Low efficiency Treated with silver (when saturated with contaminants) Treated with silver Low flowrate of water Allow higher flowrate of water

6. Benefits Efficient removal of chlorine, colour , organic matter and odour High surface area High efficiency of adsorption Easy to operate

7. APPLICATIONS Drinking water treatment River water treatment Ground water treatment Waste water treament plant
