Description
Summary:Although toxic organics may be removed from industrial effluents by activated carbon adsorbers, the cost of this process is relatively high. Furthermore, adsorber design is complex because of the unsteady-state nature of the process and the interactions between numerous design and operational variables. MASTOR, a package of computer programs that uses a dual rate adsorption model for slow adsorption phenomena, was developed to help minimize the ultimate cost of four types of column configurations. Using batch data, this package couples simulation with cost equations to produce a complete cost evaluation. It determines the effect on treatment facility costs of different values for design and operational variables, such as empty bed contact time (EBCT), hydraulic loading, and column configurations. The results of a sample problem indicate that the optimum EBCT for all the column configurations was significantly higher than values typically used by designers.
