Investigated the liquid extraction method for possibility to sewage treatment of oils production plants. The mixture of organic solvent (extractant) for selective removal of the main pollutants of wastewater was selected. The resulting equilibrium line and operating line process was obtained. Established transfer steps number. The mathematical model of liquid-extraction wastewater treatment was built. The solution of model allows to predict the kinetics of wastewater extraction for implementing the technology in practice.
This paper presents the results of experimental studies of the kinetics of ion exchange adsorption of lactic acid by zeolite in the periodic conditions. The results of experimental studies make it possible to determine the kinetic coefficients of the diffusion process
