Problem statement: A phenolic wastewater that has phenol concentration of 400 mg/L as TOC is to be treated by a fixed-bed granular carbon adsorption column for a wastewater flow of 227100 L/d, and the allowable effluent concentration, Ca, is 35 mg/L as TOC. A breakthrough curve has been obtained from an experimental pilot column operated at 1.67 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 flow rate = 17.42 L/h. Unit liquid flow rate = 0.679 L/s.m2, and the packed carbon density = 401 kg/m2 The design column is to have a unit liquid flow rate of 2.38 L/s.m2, and the allowable breakthrough volume is 850 m. Using the kinetic approach for design, determine: The design reaction constant, k1, L/s-kg. The design maximum solid - phase concentration, qo , kg/kg. The carbon required for the design column, kg. The diameter and height of the design column, m. The kilograms of carbon required per cubic meter of waste treated. . . . .
