CHAPTER 3. ACTIVATED CARBON COLUMNS PLANT DESIGN

Secondly, it was necessary to calculate pressure drop in the filter disc, that is going to support activated carbon bed in the column. This is a 50 mm filterdisc. For calculate this number, figure 2 provided by Robu has been used. The flow rate is 333.3 ml/min and curve 00 is our situation. Using this curve, pressure drop obtained is 3.5 mbar.
