A waste-water stream of F = 1 m3 /h with substrate at 2000 mg/l is treated in an upflow packed bed containing immobilized bacteria in form of biofilm on small ceramic particles. The effluent substrate level is desired to be 30 mg/l. The rate of substrate removal is given by the following equation

                   

By using the following information, determine the required height of the column (H). k = 0.5 h-1, X = 10 g/l, Ks = 200 mg/l, L = 0.2 mm, α = 100 m2 /m3 , A = 4 m2 , η = 0.8
