The validity of methods for designing fixed-bed adsorbers is experimentally examined. The breakthrough curves predicted by two design methods without the assumption of the constant pattern and three methods with the assumption are compared with those obtained from the experiments of the liquid phase fixed-bed adsorption of DBS and p-nitrophenol on an activated carbon (CAL). A diagram is presented for estimating minimum column lengths required to establish the constant pattern for the Freundlich isotherm. The validity of this diagram is also examined experimentally.
