Adsorption Technologies for Water Treatment in the Production of Fruit and Whey Drinks

Abstract

A study was made of the adsorption of chloroform from aqueous solutions on activated carbon (AC) of Ag-3, AG-OB-1, SKD-515 grades. The sorption process in kinetic and dynamic conditions is studied, the mechanism of mass transfer during the adsorption of chloroform to AC of different grades is shown. A method is proposed for optimizing the parameters and modes of the continuous adsorption purification process, based on the fundamental equation of the external diffusion dynamics of adsorption. The main parameters of the adsorption dynamics are determined: the length of the working layer, the length of the unused layer, the coefficient of protective action. On the basis of a complex study of the process of adsorption (equilibrium, kinetics and dynamics) of chloroform, optimization of the purification regime and parameters of the adsorption column using mathematical modeling, an effective technology of additional water purification from the system of centralized domestic drinking water used in the production of fruit and whey drinks was developed.
