Abstract

Abstract An algorithm is developed for integrating the differential equations modeling the operation of a continuous flow activated carbon column. This algorithm is more than an order of magnitude faster in computation than the direct numerical integration of the differential equations, and appears to be just as accurate. Computer memory requirements are small. Results are presented showing the dependence of the breakthrough curves on the parameters of the Langmuir adsorption isotherm, flow rate, influent concentrations, mass transfer rate parameter, and other quantities appearing in the model. The theory is extended to the case of several solutes competing for adsorption sites.
