Abstract
A technology for utilization of caprolactam production wastewaters has been developed. The equilibrium, kinetics, and dynamics of caprolactam adsorption from wastewaters using AG-5, BAU, AG-OV-1, and SKD-515 industrial active carbons have been studied. Optimization of the sorption filter regime was carried out by calculating the output curves based on the equilibrium adsorption layer model in the region of the linear absorption isotherm using the constants of the Dubinin - Raduszkiewicz equation, the kinetic data, and the mathematical balance equation.
