AbstractUsually chlorine added ratio during the treatment process is directly proportional to the microorganisms in water, so the use of any technique that will lead to reducing the amount of microorganisms in the water will lead to use of low concentrations of chlorine. Therefore, this study aimed to using commercial activated carbon to adsorb the rate of microorganisms such as coliform bacteria. The use of continuous adsorption system (fluidize bed) under different operating conditions and in field conditions. The results showed that the best percentage removal of coliform bacteria was 91.3% within 24 hours under the operational condition bed depth 15 cm, filtration rate 15.3 m³/m²/h and particle size 1 mm, removal rates gradually decreased with time until it reached 15% after 168 hours and went to zero after 192 hours. The results that obtained in this study proved the feasibility of the use of commercial activated carbon to remove coliform bacteria from water.
