Question

A ground water supply has been contaminated with ethylbenzene and the remedial action has been determined to be an air stripper. Please design it using the following parameters and determine a) the Stripping Factor, b) HTU, and c) the overall length of the air stripper. The maximum level of ethylbenzene in the ground water is 1 mg/L and this must be reduced to 35 μg/L using an air stripping column. You are to

K_La = 0.016 s-1

Q_w = 7.13 L/s

T = 20 ^oC

H = 6.44 x 10-3 atm m³ /gmol

H’= 0.27

Please use the following design parameters

Column diameter = 0.61 m

Air-to-water ratio (Q_A/Q_w) = 20
