Pesticides are well adsorbed on activated carbon (AC) originally prepared from olive stones ( 1200m, 1.4 gm/ml).

Pesticides are well adsorbed on activated carbon (AC) originally prepared from olive stones ( 1200μm, 1.4 gm/ml). The maximum adsorption capacity is 0.003 mmol/ml of AC. Assume that the process of irrigation water treatment with a batch of 250 m3 contains 12 ppm flows BET isotherm (k= 0.064, n= 1.13), determines the volume of the bed needed to run at 95% efficiency of adsorption. If the process was implemented continuously at ambient conditions with a flow rate of 12 m3/h to a 0.5 m diameter AC column where the bulk density is 0.8. Determine the anticipated exit pressure
