Abstract

A numerical simulation of pollutant breakthrough curves in the course of its passing through an adsorbent-filled filter column in the approximation of a stack of 20 theoretical plates is carried out. A model is proposed based on the standard S-shaped dependence in the form of logistic function depending from an ‘internal time’ of the adsorption, calculated using the Langmuir isotherm. A general equation for mathematical description of the profile of the breakthrough curve is derived in analytical form describing the process of polluted media treatment by dynamic sorption in filter column with fixed-bed adsorbent layer.
