note that X=6.5 m^3

Y=0.13 kg phenol/ m^3

Z=5.0 kg

Question 4 A wastewater solution having a volume of X m (Refer Note 1) contains Y kg phenol/m of solution (Refer Note 1). The solution is mixed thoroughly in a batch process with Z kg (Refer Note 1) of granular activated carbon until equilibrium is reached. Assume that only physical adsorption occurs between phenol and the activated carbon. The process follows the Freundlich isotherm as given below 9 = 0.199c0.229 The equilibrium data for this system is shown in Table Q4. Table Q4: Equilibrium data c, (kg phenol/m solution) 9. (kg phenol/kg carbon) 0.322 0.150 0.117 0.122 0.039 0.094 0.006 0.059 0.001 0.045 a) b) c) Define adsorption and its differences with absorption using a schematic diagram (6 marks) Show the material balance for this case. (3 marks) Calculate the final equilibrium values of the concentration of phenol in both the solution and in the adsorbent (You may use a graph paper or Excel as your working. You must include the working as an attachment in your submission) (10 marks) Determine the extracted phenol in percentage (2 marks) Your colleague had proposed to use the ratio of Z kg of activated carbon to treat X m' wastewater containing Y kg phenol/m of solution to scale-up the batch adsorption process for industrial applications. As a process engineer, justify with reasoning whether this proposal is suitable to be implemented as a full- scale batch adsorption operation. (4 marks) d) e) (Total: 25 marks)
