CHAPTER 3. ACTIVATED CARBON COLUMNS PLANT DESIGN 119 Linear Velocity = 10 m/h Surface area = 19.6 cm2 Thus, flow rate is 19.6 l/h. In the real situation this flow will be 20 l/h, so linear velocity will change, but not too much (10.2 m/h). The other important operating parameter is the empty bed contact time (EBCT), that can be calculated using:
