A granular activated carbon column with a diameter of 3.0 m and a depth of 4.0 m is used to remove an SOC from a drinking water supply at a flow of 2.0 m3/min. The apparent density of the activated carbon is 500 kg/m3. The ratio of bulk density to apparent density is 0.85. Find the carbon usage rate in kg/ (1000 m3) if the time to breakthrough occurs at 5,000 bedvolumes
