The Technology of Wastewater Purification from Dimethylformamide
https://doi.org/10.18412/1816-0395-2018-3-46-50
Abstract
The porous characteristics and chemical state of the surface of coals AG-OB-1, AG-5, SKD-515, differing in the production method and properties are determined. A complex study of the adsorption of dimethylformamide on active charcoal (equilibrium, kinetics, dynamics, simulation) was carried out. Specific features, characteristics and mechanism of adsorption of dimethylformamide from aqueous solutions with industrial active coals have been established. The characteristics of equilibrium adsorption, the limiting stage and the mass transfer coefficient are determined. The parameters of the adsorption column and the regime of continuous purification are calculated. Optimization of the process was carried out. On the basis of experimental and theoretical studies, a technology for wastewater treatment from dimethylformamide has been developed, which provides resources saving and environmental protection.
