A wastewater that has TOC concentration of 200 mg/L is to be treated by a fixed-bed granular carbon adsorption column for a wastewater flow of 227 m³/d, and the allowable effluent concentration, Ceff, is 20 mg TOC/L. A breakthrough curve (see below) has been obtained from an experimental pilot column operated at 2.36 BV/h. Other data concerning the pilot column are as follows: inside diameter = 9.5 cm, length = 1.04 m, mass of carbon = 2.98 kg, liquid flowrate = 17.42 L/h, unit liquid flowrate = 0.679 L/s-m?, and the packed carbon density = 401 kg/m³. The design column is to have a unit liquid flowrate of 2.38 L/s-m2. Use the scale-up approach to design the column. Provide the volume of design column, height and diameter of the column, mass of activated carbon required, volume of water treated at breakthrough, and service time.
